This paper describes a femtosecond X-ray source using a laser-Compton scheme, which is an interaction between a relativistic electron beam and a high-intensity laser beam. The system is constructed of a picosecond electron beam source based on a linac with a photocathode RF gun and a 1-TW Ti:sapphire laser. Experimental studies and new applications of the laser Compton X-ray beam are summarized.
