Operations in 2007

Smooth startup and very good beam performance during the commissioning and the short physics run

38 OPERA events in bricksgt 400 events from interactions outside OPERA detector

After successive failures in the ventilation system and despite the efforts made by the TSCV team to save the situation the physics run was stopped on Monday October 22nd five days ahead of schedule

The failures in the ventilation system control electronics due to radiation prevented switching to access mode in a safe manner This is intolerable for an INB facility thus it was decided to stop the beam

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

Proposed layout ndash additional shieldingRequired reduction factor ~104

Typical shielding ~16m Fe + ~2m concrete but hermetic

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

After successive failures in the ventilation system and despite the efforts made by the TSCV team to save the situation the physics run was stopped on Monday October 22nd five days ahead of schedule

The failures in the ventilation system control electronics due to radiation prevented switching to access mode in a safe manner This is intolerable for an INB facility thus it was decided to stop the beam

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

Operations in 2007

Smooth startup and very good beam performance during the commissioning and the short physics run

38 OPERA events in bricksgt 400 events from interactions outside OPERA detector

After successive failures in the ventilation system and despite the efforts made by the TSCV team to save the situation the physics run was stopped on Monday October 22nd five days ahead of schedule

The failures in the ventilation system control electronics due to radiation prevented switching to access mode in a safe manner This is intolerable for an INB facility thus it was decided to stop the beam

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

Proposed layout ndash additional shieldingRequired reduction factor ~104

Typical shielding ~16m Fe + ~2m concrete but hermetic

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

Proposed layout ndash additional shieldingRequired reduction factor ~104

Typical shielding ~16m Fe + ~2m concrete but hermetic

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

Proposed layout ndash additional shieldingRequired reduction factor ~104

Typical shielding ~16m Fe + ~2m concrete but hermetic

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

Proposed layout ndash additional shieldingRequired reduction factor ~104

Typical shielding ~16m Fe + ~2m concrete but hermetic

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

Summary

The electronics that failed were installed in the TSG4 gallery next to the ventilation ducts and in the TCV4 balconywhich has direct ldquoviewrdquo in the target chamber

In both areas the radiation levels as predicted by the simulations are far too high for COTS components

the electronics should have failed and they did

No failures to electronics in the TSG4 ldquosaferdquo area were observedShould not have happened according to radiation maps for the beam intensities we had however

would have happened if we were running longer

The AB Dept Management has setup a Crash Effort Program to address the problem and assure the on‐time restart of the facility according to schedule in May 2008

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008

ie-SPSC-04Dec07 ABATB-EA - CNGS 23

Summary

With the proposed layout all the features of the CNGS facility are maintained with minor consequences for the long term operation of the facility

The designed shielding is what can be done assuring beam on time for 2008 It is expected to suffice for one year at nominal intensity (45E19 pot) ndash however it needs to be verified by simulation studies (already ongoing but also take time)

Detailed studies of the proposed layout have started and are expected to be completed by end of Januaryrsquo08 leaving enough time for tendering production and installation in‐situ

ie-SPSC-04Dec07 ABATB-EA - CNGS 24

Summary

In addition to the ldquoelectronicsrdquo problem there are other activities in parallel

The work for the new design of the flexible striplinesThe refurbishment of spare horn to convert it to an operational spare by applying all the modifications in the water circuit as the ones installedStandard yearly maintenance activities

Yet another busy shutdown ahead for CNGS

Hope is this to be the last obstacle to overcome before delivering good and high intensity () beam to the CNGS experiments in 2008
