Fast Data-Acquisition System for the Beam-Energy-Spread-Monitor

Overview

A non-destructive beam-Energy-Spread Monitor (ESM) using multi-stripline electrodes has been developed in order to measure and control the energy spread of a single-bunch electron beam. In the KEK injector linac, the non-destructive ESM has been installed at an 180-degree arc section with a beam energy of 1.7-GeV. The data-acquisition system of ESM was developed for pulse-by-pulse measurement. This system works well and is used for a daily operation. This paper presents this DAQ system in detail.
