10 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV  Maxidiscap E1 to E4 

11 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV LEBT (SOURCE H-) 4 « LPSS » for steerer (10A bipolar, dc) 1 « LPS2 » for bending (50A, 35V, dc) CHOPPER LINE 2 « LPSS » for steerer (20A, dc)  Power part: Delta power converters ordered and at CERN  Electronic crates and different electronics cards are in progress for manufacturing.

12 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV  LPSS LPS2 E5 to E6 

13 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV 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.

14 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV

15 AB-PO-PH mars 2007J.P. Royer AB-PO-PH 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

16 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV Pulsed power converter for Klystron

17 AB-PO-PH mars 2007J.P. Royer AB-PO-PH STAND TEST 3MeV Power converters AB-PO

18 AB-PO-PH mars 2007J.P. Royer AB-PO-PH 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 ……..
