SURIYA, A SOURCE OF FEMTO-SECOND ELECTRON

A new facility, SURIYA, is being constructed at the Fast Neutron Research Facility (FNRF), Chiang Mai University (Thailand), to generate femto-second electron bunches. These bunches can be used either directly, or to create coherent far infrared radiation or femto-second Xray pulses. A 20 MeV linear accelerator has been installed and is presently equipped with a conventional electron source. A newly designed rf-gun is under rftesting and is expected to be installed in 2002. Layout and status of the SURIYA project will be presented.
