Abstract

A Smith-Purcell radiation diagnostic to measure the microbunch length of a 20 MeV, 17 GHz electron bunch train is being implemented at MIT. The bunch length can be determined by measuring the frequency and angular distribution of the emitted radiation. The beam is produced by a 17 GHz, 50 MeV/m traveling wave accelerator built by Haimson Research Corporation (HRC). The high operating frequency of this accelerator allows for the production of ultrashort bunches of about 180 femtoseconds. At this time we are assembling the experiment and we will present an update on the progress.
