We are operating the cryogenic system for the superconducting ring cyclotron in RIBF. We are operating the helium cryogenic system in the south area of RIKEN Wako campus and delivering the liquid helium to users in RIKEN. Our goal is that we collect 100% of gas helium after usage of liquid helium in Wako campus.
- Optimization of the cryogenic system for the large-scaled superconducting ring cyclotron.
- The high efficiency of the liquid heｌium production cycle.
