    • KLYSTRON MODULATOR

  • 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

    • 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 ……..
