  15. STAND TEST 3MeV • MODULATOR PROTOTYPE • The most important parts have been ordered ( ex: capacitors, high voltage pulse transformer, power converters for charging capacitors and for filament heater, H.V. switch, etc…). • Mechanical assembling has begun. • Preliminary tests of components in lab are in progress. • Planning: first tests with klystron foreseen 15-9-2007 AB-PO-PH mars 2007 J.P.

  18. STAND TEST 3MeV • CONCLUSION for the different power converters: • Team PO/PH responsibility for 27 power converters ( High Voltage, pulsed or DC) • The planning is well followed to respect the general planning STAND TEST 3MeV. • Effort will be necessary to integrate, to test and to commissioning equipments • Permanent effort (mechanical design, manufacturing) for the high voltage pulsed power converter for klystron modulator. • Sometimes conflicts with other business: work for shut down, hardware test for start–up accelerators etc… • So we continue to go ahead ……..
