METHOD AND APPARATUS FOR MAKING CRYOGENIC CLUSTER/SLUSH GAS TARGET

摘要

PROBLEM TO BE SOLVED: To provide a method for making a cryogenic cluster/slush gas target enabling efficient generation of a femto second electron induced by a plasma cathode by driving a femto second laser beam into a target by a bench-top laser system and efficient generation of a femto second neutron via a D+D nuclear fusion reaction induced by driving the above laser beam. SOLUTION: The apparatus for making the cryogenic cluster/slush gas target comprises an upper structure 10 having a supercriticality creating chamber 10, a pressure reduction chamber for making the slush gas, a heat insulation means 16 provided between the upper structure 10 and the pressure reduction chamber 20 and a laser beam radiation port 21.
