3. Decay Solenoid Power Supply & QD System Upgrade • 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. Existing PSI Power Supply & QD System in MICE Hall

4. Decay Solenoid Power Supply Replacement FuG - Superconducting Magnet Power Supply - 10V, 1000A Discharge Resistors Transistor Bank for Output Regulation Rectifier & Smoothing Capacitors FuG - Superconducting Magnet Power Supply - 8V, 1000A Main DC contactor

5. Quench Detection System Upgrade • 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. DL Quench Detection System

6. Rack Room 2 – Step IV Equipment Layout 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. • Room infrastructure progressing well, handover planned for cable management installation in March 2014.

7. Rack Room 2 – Infrastructure New Door Access Cable Access into RR2 Cable Management under stairs Cable Management from Hall

8. Rack Room 2 – AC Electrical Distribution Main AC Supply for Critical Loads via UPS Main AC Supply for General Distribution 208V Transformer Lighting replaced and main AC feeder installed

9. AC Distribution for RR2 up to Step VI All Critical systems are fed via the 30KVA UPS with 1 hour autonomy. AC Distribution separated into Critical systems and General distribution Main Hall Board 208V Transformer 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

10. Rack Room 2 – UPS Inverter and Batteries As the total load will be significantly lower than 30KVA the autonomy will be >1hour UPS for Critical Loads Riello UPS – Sentry unit 3 Phase - Double Conversion Technology

11. Rack Room 2 – Cooling Channel Racks Step IV FC & SS Power Supplies, Instrumentation and Control Racks Racks allocated up to Step VI

12. Cooling Channel Rack Configuration Blister Front Back Cooling Channel Control Rack FC Control & Instrumentation Rack Spectrometer #1&2 Control & Instrumentation Rack FC Power Supply Rack Spectrometer #1 Power Supply Rack Spectrometer #1&2 Discharge Circuit Rack Spectrometer #2 Power Supply Rack • All 7 Cooling Channel Control & PSU racks to be located in RR2 are designed and assembled as far as possible. • RR2 installation is scheduled for May 2014.

13. Focus Coil & Spectrometer Solenoid Control Racks Racks allocated for Step V & VI Cooling Channel Control Racks - Step IV Spare • These 3 racks have been designed, assembled and partially commissioned. • Awaiting procurement / delivery of instrumentation to fully populate.

14. Focus Coil & Spectrometer Solenoid Control Racks Racks viewed from rear Cooling Channel Control – VME crates, CANBUS modules, ADC, DAC and serial interfaces. FC & SS Control - He level gauges, temperature indicators / controllers, pressure indicators and interfacing.

15. Focus Coil & Spectrometer Solenoid PSU Racks Cooling Channel PSU Racks - Step IV Racks allocated for Step V & VI • These 4 racks are all designed. • Assembly is completed apart from SS#2 PSU rack.

16. Focus Coil & Spectrometer Solenoid PSU Racks FC PSU Rack-Rear SS PSU Rack-Rear SS PSU Rack-Front FC PSU Rack-Front • Assembly and commissioning can only be completed after procurement / delivery of instrumentation (SS#2 PSU rack requires DC contactors). • Racks are partially commissioned.

17. Spectrometer Solenoid Energy Absorber Rack Items Required Energy Absorber Rack-Rear with and without DC Cables • 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)

18. Instrumentation required for FC & SS Racks • 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. Control & Instrumentation racks operational at WANG and RAL R9

19. Rack Room 2 – QD & QP Systems FC QD & QP System 3 Racks allocated for the QD & QP systems for FC, SS & RFCC SS QD & QP System All Step IV systems fully installed and commissioned by Nov 2014

20. Quench Detection & Protection Racks • 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. SS QD / QP System rack FC QD / QP System rack RFCC QD / QP System rack

21. Diffuser and Tracker Control Rack Cooling Chanel Control Racks for Step IV • The rack design is being developed with the work package managers. • The rack will be assembled ready for population with equipment by Summer 2014.

22. Compressor & Vacuum Control Rack • 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

23. 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, FCand downstream SS. • Peak resource loading will occur between July and November 2014 and will need to be carefully co-ordinated.
