1-Indian collaboration (100kV, 20A, 800 microsec, 2Hz)

2-Prototype AB-PO (100kV, 20A, 800 microsec, 2Hz)

It was foreseen to start the stand test 3MeV with the Indian modulator but now, due to the delay, the PO prototype will be installed for operation.

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



Pulsed power converter for Klystron



Power converters AB-PO



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 ……..
