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
