Characterization and alignment of a resonant cavity beam position monitor for the Compact LInear Collider (CLIC) project at CERN

The compact linear collider CLIC

A high luminosity 1034–1035 cm−2 s−1 electron–positron Collider (CLIC) with a nominal centre-of-mass energy of 3 TeV is being studied since a number of years at CERN within an international collaboration of laboratories and institutes to provide the HEP community with a new accelerator-based facility for the post-LHC era. In order to achieve the very high design luminosity, very low emittance b...

CERN EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH PHYSICS AT THE CLIC MULTI-TeV LINEAR COLLIDER

This report summarizes a study of the physics potential of the CLIC e+e− linear collider operating at centre-of-mass energies from 1 TeV to 5 TeV with luminosity of the order of 1035 cm−2 s−1. First, the CLIC collider complex is surveyed, with emphasis on aspects related to its physics capabilities, particularly the luminosity and energy, and also possible polarization, γγ and e−e− collisions. ...

Status of the Re-entrant Cavity Beam Position Monitor for the European Xfel Project

The European XFEL is a research facility, currently under construction in Germany. It is based on a superconducting electron linac including about 100 cryomodules based on the TESLA technology. Each cryomodule is equipped with a beam position monitor connected to a quadrupole at the high-energy end of the cavity string. Around one third of cold BPMs will be reentrant RF cavities. This contribut...

Lcls Resonant Cavity Beam Position Monitors *

The Linac Coherent Light Source (LCLS) is a freeelectron laser (FEL) at SLAC producing coherent 1.5 Å x-rays. This requires precise, stable alignment of the electron and photon beams in the undulator. We describe construction and operational experience of the beam position monitor (BPM) system which allows the required alignment to be established and maintained. Each X-band cavity BPM employs a...
