  1. Commissioning & Status of ALBAPower SuppliesRoberto Petrocelli

  2. ALBA overview and commissioning • ALBA Power Converters • Booster Power Converters • Storage Ring Power Converters • Tools for the day to day business • Maintenance schedule • Conclusions

  3. Synchrotron Light Source in Cerdanyola del Vallès (Barcelona, Spain)

  4. ALBA accelerators LINAC 100 Mev BOOSTER 100 MeV – 3 GeV STORAGE RING 3 GeV

  5. COMMISSIONING SCHEDULE • Booster commissioning in parallel to SR installation 2010 • SR commissioning (1st phase) March-June 2011 • Installation Insertion Devices: SCW and IVUs Summer 2011 • SR commissioning with all IDs restarted Sept 2011 • Beam for beamlines commissioning Oct 2011 • First external users May 2012

  6. BOOSTER COMMISSIONING

  7. SR COMMISSIONING 16 March: Beam Accumulated 1.5 mA stored Acummulation Current SR Current Booster

  8. 1st synchrotron light outside the tunnel

  9. Once the MPS (to protect the machine) was operational…

  10. LIGHT from APPLE-II UNDULATOR Beam Image at Fluorescent Screen on the FE • Screen @ 9.35m from source (middle of straight section) • Source  APPLEII undulator EU62 • Stored current I=0.8mA Minimum gap (15.5mm): Horizontal mode (K=5.2) Circular mode (K=3.0) Vertical mode (K=3.7)

  11. EMITTANCE

  12. ORBIT STABILITY 1week data 1shift (8h) data SLOW ORBIT FEEDBACK RUNNING 0.3 Hz 88 BPMs 88 CORH & 88 CORV FAST ORBIT FEEDBACK UNDER DEVELOPMENT

  13. 2012 In Operation • Beam-Line Users since May • 24 Hour operation • 2 injections. • Expected 2000 hours for Beam Lines and 1200 for Machine studies

  14. Magnet Power supplies at ALBA Distribution of Power Supplies in the Service Area

  15. Range of Magnet Power Supplies

  16. BOOSTER PCs

  17. Major Incidences with main BO PS

  18. Major Incidences with main BO PS Noise in Buck Module of BO_Bend_01 Buck input current

  19. SR PCs

  20. 7 incidences with SR Quad (200A x15V).

  21. TOOLS FOR DAY TO DAY BUSINESS • PS Logbook • PS database • TRAINING OF OPERATORS

  22. PS Logbook

  23. 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 )

  24. 2012 MAINTENANCE Terminal not Crimped

  25. 2012 MAINTENANCE Fan out of order

  26. STATISTICS Operation for users

  27. Next Steps • Fast Orbit Feedback. • Project of Power supplies for future upgrades.

  28. Conclusions • It is not realistic to expect to find all the problems during FAT, SAT and commissioning.
