Description

The Siam Photon Source (SPS) operates a 40-MeV electron linac as the pre-injector for its synchrotron light source complex. Reliable operation of the injector is critical for maintaining efficient injection into the booster synchrotron. This paper presents recent beam measurements conducted on the SPS injector linac to characterize its transverse and longitudinal beam properties. Key beam parameters, including transverse emittance, beam energy, and energy spread, were measured using the quadrupole scan technique and analyzing magnet systems. The measurements yielded a normalized emittance of 50 mm-mrad and an energy spread of about 20% at a nominal energy of 38 MeV. This significant energy deviation and large energy spread highlight the need to investigate the effects of the buncher phase and accelerating structure temperature. The results provide a baseline for future optimization of the injection chain.
