It was replaced on all control boards 6 14.09.10 Bend 1 Auxiliary power supply Replaced 7 15.11.10 QV02 PWM board failure Repaired at ALBA 8 24.01.11 QS180 PWM board failure Repaired at ALBA 9 24.01.11 Bend 1 & 2 Auxiliary power supplies Replaced 10 27.04.11 Bend 1 2Q module failure Repaired at ALBA by Bruker 11 29.04.11 Bend 2 2Q module failure Repaired at ALBA by Bruker 3rd to 7th of May - Bruker slowed the start and stop procedures 12 16.05.11 QH02 Snubber resistor failure Repaired at ALBA 13 23.05.11 Bend 1 Buck module failure Sent to the factory for repair 14 20.04.12 Bend 1 2Q module failure failure Replaced by spare module POCPA 2012 Major Incidences with main BO PS Noise in Buck Module of BO_Bend_01 Buck input current POCPA 2012 SR PCs POCPA 2012 7 incidences with SR Quad (200A x15V). POCPA 2012 TOOLS FOR DAY TO DAY BUSINESS PS Logbook PS database TRAINING OF OPERATORS POCPA 2012 PS Logbook POCPA 2012 2012 MAINTENANCE SCHEDULE 5 WEEKS FOR MAINTENANCE ( distributed along the year) MAIN TASKS WE DO Connection Checks Rotate Spare Power Supplies Check calibration in Booster and SR Bendings. Perform annual test required by authorities ( CSN ) POCPA 2012 2012 MAINTENANCE Terminal not Crimped POCPA 2012 2012 MAINTENANCE Fan out of order POCPA 2012 STATISTICS Operation for users POCPA 2012 Next Steps Fast Orbit Feedback. Project of Power supplies for future upgrades. POCPA 2012 Conclusions It is not realistic to expect to find all the problems during FAT, SAT and commissioning. POCPA 2012 Thank You ! Questions ?
