| Abstract |
To increase user experiment chances at SACLA, Equipping a new beamline and an additional linac as a further FEL driver is effective. For this reason, the SCSS test accelerator as the prototype of SACLA is reused and improved, because of terminating its role. SCSS with an electron beam energy of 250 MeV generated an extreme ultraviolet laser with 50-60 nm. We relocated SCSS into the SACLA undulator hall and improved its performance. Three newly designed C-band accelerator-units for the relocated SCSS accelerator with an acceleration gradient of 47 MeV/m at maximum boost an electron beam energy of up to 420 MeV. By FEL simulation, the EUV-FEL with 30-40 nm and 100 uJ are expected in conditions of the electron energy and 2 modified undulators with 5 m long each. As a further capability, the relocated SCSS accelerator has space to add 9 C-band accelerator units and 2 undulators and the units increase a beam energy of up to 1.4 GeV, as which can generate a soft X-ray FEL. The relocation of the accelerator was finished in the summer of 2014 and its RF conditioning was now started. This paper describes the relocation and improvement status of the modified SCSS accelerator.
