LiSoR, a liquid metal loop for material investigation under irradiation

Preliminary results of post-irradiation examinations on LiSoR-2 test section

“…While on the back side of the tube, no beam footprint can be seen. This indicates that the proton beam could not penetrate the whole test section which is in agreement with neutronics calculation [6].…”

“…For the tensile specimen, the temperature was lower due to cooling from both surfaces by flowing LBE. However, the heat deposition in the specimen was about 1.5 times of that in the wall of the tube [6]. This resulted in a maximum temperature at the middle of the specimen of about 620 and 580°C at the surfaces.…”

“…The details of the LiSoR facility can be found in the previous report [6]. The parts exposed to the proton beam are the tube and tensile specimen in the test section.…”

“…Preliminary neutronic calculations indicated that the irradiation of 72 MeV protons could closely simulate that of 600 MeV protons in terms of radiation damage rate, helium, hydrogen and other transmutation elements production. With collaboration between PSI and Subatech, France, a LBE loop has been set up [6]. The test section of the loop consists of a tube and a tensile specimen.…”

Materials irradiation facilities at the high-power Swiss proton accelerator complex

“…Details of the LiSoR loop can be found in previous reports [4,5]. It has an exchangeable test section housing the test specimen, the whole loop being designed and constructed for operating in the environment of a proton beam bunker.…”
