Performance of the 100 MeV injector linac for the electron storage ring at Kyoto University

An electron linear accelerator has been constructed as an injector of a 300 MeV electron storage ring (Ralren Storage Ring, KSR) at Institute for Chemical Research, Kyoto University. The output beam energy of the linac is 100 MeV and the designed beam current is 100 mA at the 1 mu sec long pulse mode. The transverse and longitudinal emittance are measured to evaluate the beam quality for the beam injection into the KSR. They are observed by the profile monitors combined with quadrupole magnets or an RF accelerator. The results are that the normalized transverse emittance is 120 pi.mm.mrad. The longitudinal emittance is 15 pi.deg.MeV and the energy spread is +/-2.2 %.
