Abstract: IN ORDER TO SIMULATE THE EFFECTS OF 14 MEV NEUTRON DAMAGE IN MATERIALS TO BE USED IN THE DIVERTOR OF A TOKAMAK FUSION REACTOR, IRRADIATION WAS UNDERTAKEN USING 18 MEV PROTONS PRODUCED BY A CYCLOTRON. THE MATERIALS INVESTIGATED WERE OXYGEN FREE HIGH CONDUCTIVITY CU AND A CU-CR-ZR ALLOY FROM WHICH THIN MINIATURIZED SPECIMENS WERE PRODUCED FOR TENSILE TESTING AND MICROHARDNESS MEASUREMENTS. TESTING OF UNIRRADIATED MATERIAL DEMONSTRATED THAT AT SPECIMEN THICKNESS BELOW 0.5 MM THE PRIMARY EFFECT OF DECREASING THE THICKNESS FURTHER WAS THAT OF LOWERING THE DUCTILITY, WHILST THE YIELD STRESS AND ULTIMATE TENSILE STRENGTH REMAINED UNCHANGED.
