A High-Resolution Beam Intensity Profile Monitor

Beam Intensity Profile Monitor

This paper describes an intercepting beam intenSity profile and position monitor which was developed at SLAC. It has excellent spatial resolution as well as signal efficiency. The instrument utilizes the electromagnetic cascade shower emission effect. Net charge leakage signals comparable in magnitude to the intercepted beam current are easily obtainable. The latest model of the instrument is d...

A Versatile High Resolution Beam Position Monitor*

A new kind of Cerenkov beam position monitor is described. The counter, though relatively simple and inexpensive, has high sensitivity, introduces a minimal amount of multiple scattering, and is capable of high spatial resolution over a wide range of beam currents 0 Measurements of the position of the SLAC electron beam to an accuracy of I l/2 mm have been made for electron currents from 20 nA ...

Tagging of alpha particles with a large scale, high timing resolution beam profile monitor

A prototype of a new beam profile monitor with tracking and TOF capabilities for degraded beams at HISPEC/DESPEC at FAIR has been built at the Institute of Nuclear Physics at the University of Cologne [1]. The device constists of two detectors in series, each with an active area of 80x100mm. The working principle is based on secondary electrons being created by the ions passing through a thin s...

A Proposal to Test A High Resolution, Single Bunch, Beam at the SLAC Final Focus Test Profile Monitor Beam

Scanning Electron Beam Profile Monitor

A scanning beam profile monitor is described that was developed for use along the Stanford two-mile linear accelerator. The maximum beam loss due to scattering caused by this monitor can be made to be a small fraction of that which would be caused by a Cerenkov radiator or scintillating screen.
