MICE Amplifier Refurbishment

MICE Amplifier Refurbishment

MICE Amplifier Refurbishment To be done (by MICE collaboration): Delivery to Daresbury RF power testing with proper HV supplies and RF loads Final adjustment of output loops Caveat (as mentioned before): The amplifiers operated at maximum 1.7 MW at CERN 2.5 MW were reached in the 1950s but with sparking problems With 2 loops we think that 2 MW are within reach So, we are curious: How far in power can you get? Powering of two cavities from one PA …
