Abstract: Operation mechanism of SASE-FEL and special characteristics of X-ray beam available from it will be firstly described.The talk will also cover Japanese activity in this field, especially on the new soft-X-ray SASE-FEL project at SPring-8.This project was named SCSS: SPring-8 Compact SASE Source, which has been funded in 2001, aims to generate first light in 2004 at VUV and soft-X-ray regions.The following key technologies makes total machine size compact, less than 100 m long.(1) The short pitch undulator with 15 mm period using the in-vacuum undulator technology, which has been developed at SPring-8.(2) C-band (5712MHz) RF acceleration system with very highgradient acceleration field (35 MV/m), which has been developed at KEK for the e + e -Linear Collider project.(3) Low emittance electron gun with 500 kV pulsed acceleration, using single crystal CeB6 cathode, which will generate 1 nC charge with 1 mm-mrad emittance.This is totally new design, will be developed at RIKEN/SPring-8 in few years.
