Cavity Beam Position Monitors
Beam-based alignment and feedback systems are essential for the operation of future linear colliders and free electron lasers. A certain number of beam position monitors with a resolution in the submicron range are needed at selected locations. Most beam position monitors detect the electric or the magnetic eld excited by a beam of charged particles at di erent locations around the beam pipe. I...
متن کاملEffects of Transverse Beam Size in Beam Position Monitors∗
The fields produced by a long beam with a given transverse charge distribution in a homogeneous vacuum chamber are studied. Signals induced by the displaced finitesize beam on electrodes of a beam position monitor (BPM) are calculated and compared to those from a pencil beam. The non-linearities and corrections to BPM signals due to a finite transverse beam size are calculated for an arbitrary ...
متن کاملThe Calibration of BEPC Beam Position Monitors
The basic requirement for the BEPC beam position monitor is the measurement of the beam orbit with 0.1 mm precision near the collision point. To improve the measurement accuracy, the response of the beam position monitor pickups was mapped in the laboratory before they were installed in the BEPC ring. The microcomputer-controlled test set consists of high frequency coaxial switches to select ea...
متن کاملLcls 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...
متن کاملBeam Position Monitors for the Sns Linac
The Spallation Neutron Source (SNS) linac accelerates 52-mA peak of pulsed Hparticles to over 800 MeV. There are three types of accelerating structure in which the beam position must be measured: the drift-tube-linac (DTL); cavity-coupled-linac (CCL); and superconducting-linac (SCL)[1,2]. Beam with a 402.5-MHz structure is injected into a 402.5 MHz DTL, followed by 805-MHz CCL and SCL structure...
