Bunch Extension Monitor for LINAC of SPIRAL2 Project

Abstract : A semi-interceptivemonitor for bunch shapemeasure-ment has been developed for the LINAC of SPIRAL2. A Bunch ExtensionMonitor (BEM) is based on the registra-tion of X-rays emitted by the interaction of the beam ions with a thin tungsten wire. The time difference between detected X-rays and accelerating RF gives information about distribution of beamparticles along the time axis. Thesemonitors will be installed inside diagnostic boxes on the first five warm sections of the LINAC. The monitor consists of two parts: X-ray detector and mechanical system for positioning the tungsten wire into the beam. Emitted X-rays are registered by microchannel plates with fast readout. Signal processing is performed with constant fraction discriminators and TAC coupled with MCA. Results of bunch shape measurements obtained during commissioning of RFQ for SPIRAL2 are presented.
