STATUS OF HOSTATUS OF HOSTATUS OF HOSTATUS OF HO

During May, while installing the HO trays into the honeycomb panels, a problem was noticed in the panels.

The inner c-channels were to be glued to the honeycomb panels on both sides. But the amount of glue applied was not enough and hence the channels were getting unglued.

It was decided to do the repair of all the panels and then do the insertion of the trays.

Pascal tried a procedure of fixing nuts and screws on the mockup and found it to be satisfactory.

K.Sudhakar, CMS Week, Sept ‘04K.Sudhakar, CMS Week, Sept ‘04K.Sudhakar, CMS Week, Sept ‘04K.Sudhakar, CMS Week, Sept ‘04



Same procedure, of fixing nuts and screws between the c-channels and honeycomb panels, was decided to be applied to all the panels and the materials needed were procured.

Pascal has devised the tools needed for carrying out the necessary work.

During last week of August our people came and carried out repair on 3 panels. Along with Pascal we checked the repaired panels for pressure test, sagging, tray insertion in order to validate them.



The panels were tested up to a pressure of 1 bar

The sagging was within 3 to 4 mm with load.

The tray insertion was also smooth without any obstruction from the nut heads(0.7 mm)

So the procedure was validated and we are making 10 holes along the 2.5 meter length of the c-channel. Every panel will have 100 nuts fixed.

The repair work was shifted from B184 to B186 area. The space is limited here (unlike in B184)



The work started with R+2 panels (i.e. YB+2) from 10th September

Already 9 panels were repaired and tray insertion was done. No problems were noticed while lifting the stuffed panels.

Right now the speed is about 1 panel a day and is expected to pick up and may go up to about 1.5 panels a day



The panels will be repaired in the order of the needs of the overall mounting schedule

R+2, R+1, R0, R-1, R-2

Expected to complete repair of all 72 panels by about mid November.

The overall installation schedule will not be affected



Using the Autocad drawings provided by Dattola for the outer wheels and the RBX positions given by Randy et al, the lengths of optical cables were worked out for R+2.

The cables for two adjacent sectors were made and brought to CERN for validating the lengths and the routing of the cables.

Dummy panels with connectors (both on tray side and RBX side) are being made for carrying out this in SX5 and will be done in the next 10 days.



Once the validation is done, the cables for full Ring will be fabricated.

For wheel 0, the validation will have to be carried out again at a later date after getting the final drawings from Dattola and working out the lengths of the cables.

Our people have participated in the testbeam runs and analysis has been carried out



There was a short meeting with A. Gurtu, myself, Pascal Petiot, Pawel de Barbaro and Austin Ball present in it.

Basically we went over the schedules concerned with HO mounting and cabling.

Tentatively the periods for installation of cables (optical and HV, LV cables) was indicated as

March/April 2005 for YB+2

August 2005 for YB+1 and YB0

Spring 2006 for YB-1 and YB-2
