抄録

The purpose of KEK-STF (Superconducting Test Facil- ity) is to establishsuper-conducting accelerator technology for ILC (International Linear Collider). Anotheraim is MEXT Quantum Beam project which is a high brightness X-ray generation by inverselaser Compton scattering. In both projects, high intensity electron beam in multi-bunch andlong macro-pulse is essential. An L-band normal con- ducting RF gun was fabricated byDESY-FNAL-KEK col- laboration and the cavity conditioning was performed since 2010. Thecavity conditioning dramatically reduced the un- wanted dark-current by two orders ofmagnitude and it is 100μA at 40 MV/m gradient typically. In the beam gen- eration testfrom February 2012, 1.0 ms macro pulse was successfully generated in designed beamintensity.
