Amplifiers We have

6 x 352 MHz amplifiers1 x 400 MHz amplifier

We have started test with a first 352 MHz

Due to Long Shutdown 1no water -> on hold

We will restart in September

We should qualify our first400 MHz amplifierbefore end 2013

We will launch modification of3 additional 400 MHz amplifiers(4 in total) beginning 2014

AmplifiersRegarding full

reflection operation we need a circulator

We are in contact with suppliers, should not be a problem except some additional integration difficulties

FPC water cooled Regarding Power levels,

50 kW CW full reflection,i.e. 200 kW CW locallyinner antenna water cooled Helicoflex 8”

▪ OD/ID = 195/88.5 mm▪ 400 MHz – 137 kW

Helicoflex 9”▪ OD/ID = 216.7/99.4 mm▪ 400 MHz – 287 kW

Crab FPC antenna OD = 27 mm

Water tube Antenna OD/ID = 27/21 mm Water tube OD/ID=17/13 mm

CERN rule for couplers No soldering, welding,… between

water and vacuum We will have an exception on the

ceramic side

IntegrationStill a lot to do, but we

are confident that whatever the space available, we will be able to match with it

Key parameter is the distance between beam axis and the water inlet on the top of the waveguide Cryomodule design must

take it into accountEric Montesinos, CERN-BE-RF
