Abstract

The PLS (Pohang Light Source) linac has been operated routinely as the injection linac for PLS, a third-generation synchrotron light source. The transverse electron beam emittance was measured at the pre-injector end of the PLS linac, where the beam energy is about 100 MeV. The emittance was measured using a quadrupole magnet and a fluorescent target. We used a progressive scan CCD camera with an asynchronous random trigger shutter to obtain precise beam sizes. The beam image analysis was made with a PC equipped with a frame grabber. The bunch length was also measured at the pre-injector end using a streak camera to observe transition radiation emitted from a radiator inserted into the beam path. The measurement system and the results are described in detail
