Beam Position Monitors - Baseline

High accuracy (5um) resolution (50nm) BPM in Main Linac and BDS

Very high numbers of BPMs for the DB decelerator, together with high accuracy

The much challenging requirements comes from the main Linacs.

Not only to the big numbers of instrument to beb build and maintained.

For the main linac we need 4000 high resolution/high accuracy BPMs. With 50 nm resolution. In the BDS down to 3nm. Resoultions in the order of 10nm has been demonstrated but with high Q cavity BPMs we cannot due to the required time resolution. In ATF2 the highest number of cavity BPMs in history 30pc

For the DB more than 40000 which demands a close eye on costs and simplicity both for manufaturing and maintenance1% down means 400 BPMs down

Outside the main linacs we have another 8000 BPMs almost 10 times more than LHC

Challenges CLIC Main Beam 50n with 10ns time resolution, low Q stainless steel

Three BPM types and three different acquisition system types

Cavity BPM 14GHz

Damping ring BPM 2 GHz

Direct sampling 2-500MHz

Calibration is mandatory to obtain the high demands on accuracy, which increas the complexity significantly.
