Review of existing CTF3 BPM’s and related dataacquisition Lars Søby CTF3-CLEX meeting
BPE • Electrostatic PU. • Ceramic tube containing 4 electrodes. 4 feed-thru • 2 units in Linac • High impedance buffer followed by standard acquisition system Lars Søby CTF3-CLEX meeting
BPI • WCM type PU using current transformers. • Racetrack vacuum chamber. • 4 electrodes, no feed-thru. • Delay loop + Linac 19 units. No analogue electronics. • CR +TL1 27 units is foreseen. Standard acquisition system. • TL2 ?? Lars Søby CTF3-CLEX meeting
BPM • WCM type PU using current transformers. • Circular vacuum chamber. • 8 electrodes, no feed-thru. • 23 units in the Linac. • CR +TL1 6 units is foreseen. • TL2 ?? • Standard acquisition system. Lars Søby CTF3-CLEX meeting
BPR • Button PU and wave guide port. • Circular vacuum chamber. • 4 buttons with feed-thru. • 2 units in the Linac, 1 in the CT line. • CR 1 unit is foreseen. • TL2 ?? • Down mixing using 3GHz reference • Wave guide detector. • Standard acquisition system. Lars Søby CTF3-CLEX meeting
WCM • 7GHz WCM. • Circular vacuum chamber. • 2 mm air gap. 8 feed thrus • 3 units in the Linac. • 1 unit at exit of delay loop. • 1 is foreseen for TL2 • Standard acquisition system for low frequencies. Lars Søby CTF3-CLEX meeting
