1.- CCS System(CCS Vacuum and Thermal Tests)
CCS Vacuum and Thermal Test Campaign (Crisa facilities)
CCS Thermal Design Validation as main objective
Hottest temperature Monitoring during Ramp-up sequence and Steady State
Additional Thermocouples included to monitor the hottest points of CCS
CCS Thermal Test Report, including description of the Thermal Model used and the correlation with CAB detailed Thermal Model, is under preparation. It will be distributed to TWG for review.

1.- CCS System(CCS Pending Actions)
Protections at CCS board level OC Protection Circuitry of the of the SR Power Supply of the 28V Interpoint CV modules Update the UV protection values at 109V instead of 95V Current Limitation at 95A for each CCS converter board Add TVS at the input stage of the SC SW
Protection circuitry Design, Manufacturing and Tests foreseen between Jan_07 and Apr_07
Protections at the CCS output Crisa has assessed the need of adding TVS “Transient Voltage Suppressors” at CCS output To foresee Transient voltages when opening the Persistent Switch at the end of Ramp up sequence or
opening the SC SW in case of aborting the Ramp up sequence during a power loss Objective: To protect the Mosfet of the SC SW during the Ramp up sequence Electrical design is available Physical design is on going
