SINQ Target Irradiation Program (STIP) was setup by G.S. BauerSINQ Target Irradiation Program (STIP) was setup by G.S. Bauer in 1996 in Oak Ridge, joined by CEA, FZJ, JAERI, LANL andin 1996 in Oak Ridge, joined by CEA, FZJ, JAERI, LANL and ORNL to irradiated test samples in SINQ (solid) targets. ORNL to irradiated test samples in SINQ (solid) targets.
Now, the collaboration has been greatly enlarged, including Now, the collaboration has been greatly enlarged, including CIAE(ADS),CSNS, CRPP/EPFL (fusion), LWV/PSI (Gen-4), CIAE(ADS),CSNS, CRPP/EPFL (fusion), LWV/PSI (Gen-4), UCSB (fusion). UCSB (fusion).
The goal: -- to establish necessary data base of mechanical propertiesThe goal: -- to establish necessary data base of mechanical properties of different structural and target materials; of different structural and target materials; -- to understand the changes in structural and target materials -- to understand the changes in structural and target materials after irradiation under spallation spectrum in different after irradiation under spallation spectrum in different environments in wide temperature range. environments in wide temperature range.
