J-PARC mercury target vessel was cut in 2017. Prior to the target cutting, cutting tests were conducted to optimize cutting conditions based on the experienced difficulties in previous cutting. Improvement in specimen cutout by remote handling and results of cavitation damage observation will be reported.

The purpose of the Medium energy target autopsy is the observation of the graphite fins. The graphite fins are major component of the target that are taking beam during operation. The target ME-1 is cooled down more than one year, but is still high radioactive. The target is delivered to the C-0 Remote Handling facility and placed on the stands inside the work cell by crane and aligned with...

Thermal properties of pure tungsten, irradiated in the Swiss neutron spallation source at the Paul Scherrer Institut, have been studied in the temperature range 25-500 °C. Disk-shaped specimens were prepared from a tungsten sheet which was irradiated with approximately 550 MeV protons. The specimens tested in this work received total damages of maximum 3.9 and 5.8 dpa at average irradiation...
