Decay Solenoid Power Supply & QD System Upgrade

3Existing PSI Power Supply & QD System

in MICE Hall

• Existing Power Supply is electrically noisy and unreliable. Causing QD system to trip at currents below 150A.

• New Power Supply from FuG was procured and delivered in Sept 2013.

• Failure of a Solenoid - current lead has delayed the installation.

• Power Supply installation and commissioning is planned for April 2014.

• A new DL QD system has been installed and final commissioning is planned for March 2014.

• The DL QD system has been operated with existing Power Supply up to 150A.

• A Quench Data Logger system will be constructed to monitor the Solenoid during initial operations.

Quench Detection System Upgrade

5

• Existing system contains obsolete components.

• Combines the reliable PSI philosophy with a modern modular design.

• Tripping points are set at 20mV for most of the voltage taps except for channel 4 which is set at 40mV.

• The Voltage taps from the magnet are arranged in sets of three with overlap along the length of the solenoid.

• Not all of the voltage taps are used.

Rack Room 2 – Step IV Equipment Layout

6

• Room infrastructure progressing well, handover planned for cable management installation in March 2014.

Proposed extended MCR?

• Allocation and position of racks and equipment for Step IV agreed and finalised.• QD & QP system for SS – layout / position to be confirmed.

Lighting replaced and main AC feeder installed

208V Transformer


AC Distribution for RR2 up to Step VI

9

AC Distribution separated into Critical systems and General distribution

All Critical systems are fed via the 30KVA UPS with 1 hour autonomy.

General distribution includes DC magnet power supplies, A/C conditioning and lighting.

Critical systems includes instrumentation, controls system and cooling water for SS energy absorbers

UPS for Critical Loads

Riello UPS – Sentry unit3 Phase - Double Conversion Technology

As the total load will be significantly lower than 30KVA the autonomy will be >1hour

• Upstream SS energy absorber have been upgraded and thermally tested.• Cooling water circuits have been modified and flow indication added.• Downstream SS energy absorbers will be delivered once Solenoid training

complete. (May 2014)

Items Required


Instrumentation required for FC & SS Racks

18

• Racks will be populated once testing of the Spectrometer Solenoids is complete. Availability of FC instrumentation depends on training schedule.

• There are still power supplies and instrumentation to be procured for Step IV for both FC and SS.

• A list is being compiled of the remaining items for the SS, funding needs to be agreed for these and DC magnet / controls cables.

• The location of the FC QD systems is agreed. (for all 3 focus coils)

• Tests are being conducted to ensure reliable operation with 36m voltage tap cable lengths.

• Two FC QD systems are assembled and tested.

• One system is currently being used for training the FCs.

• The location for SS QD systems is being discussed.

• A second SS QD system is to be assembled, tested and installed before Nov 2014.

• Integration of the data logging for both systems needs to be finalised.

Diffuser and Tracker Control Rack

21

• The rack design is being developed with the work package managers.• The rack will be assembled ready for population with equipment by

Summer 2014.

Cooling Chanel Control Racks for Step IV


Compressor & Vacuum Control Rack

22

• The control system requirements for the compressors are agreed and the rack physically assembled.

• The vacuum control and instrumentation have been reviewed and equipment ordered.

• Control philosophy needs to be finalised with Vacuum specialists


Summary

• Project Plan for Step IV Electrical & Controls is fully developed and linked to the master plan.

• Resource priorities are focused on the Step IV milestones and this may affect other work packages such as RF systems.

• Electrical & Control requirements for Step IV are progressing well.

• Installation & commissioning is dependent on key milestones such as installation of South PRY, FC and downstream SS.

• Peak resource loading will occur between July and November 2014 and will need to be carefully co-ordinated.
