Abstract On 20 June, the first lasing was observed at 49 nm in SCSS prototype accelerator for Japanese XFEL project. A challenging approach: 500 kV gun using CeB6 single crystal thermionic cathode generates low emittance beam from 500 kV gun, followed by velocity bunching, and magnetic chicane bunch compression, the measured emittance at 50 MeV was 3 π.mm.mrad normalized. When we firstly closed undulator, we observed narrow spectrum of amplified SASE signal. Radiation energy per pulse is around 1 μJ/pulse at moment.
