Now, the collaboration has been greatly enlarged, including Now, the collaboration has been greatly enlarged, including CIAE(ADS),CSNS, CRPP/EPFL (fusion), LWV/PSI (GenCIAE(ADS),CSNS, CRPP/EPFL (fusion), LWV/PSI (Gen--4), 4), UCSB (fusion).UCSB (fusion).
The goal: The goal: ---- to establish necessary data base of mechanical propertiesto establish necessary data base of mechanical propertiesof different structural and target mateof different structural and target materials;rials;
---- to understand the changes in structural and target materialsto understand the changes in structural and target materialsafter irradiation under spallation specafter irradiation under spallation spectrum in different trum in different environments in wide temperature range.environments in wide temperature range.
