Cryogenics play an essential role in recent investigations in high energy physics, radiation science, neutron physics and so on. A liquid helium (LHe) system and a superconductor device are commonly used in recent high energy physics, radiation science, and neutron physics experiments.
Cryogenic Science Center contributes development, construction and operation of superconducting magnets and cryogenic systems, required for the high energy accelerator and particle physics experiments. In addition, the following research activities are conducted:

  • R&D of superconductor and cryogenic systems for high field magnets
  • R&D of superconductor and cryogenic systems under high radiation condition
  • Basic study of mechanical and electrical characteristics of materials at very low temperatures

Cryogenics Science Center has helium liquefaction systems in both Tsukuba and Tokai and supplies more than 150,000 liters of LHe to research groups in KEK for supporting their research activities.

Collaborative studies with domestic and foreign laboratories are also progressed as follows:

  • Development of superconducting quadrupole magnets for the LHC interaction region
  • Construction of KAGRA (Large-scale Cryogenic Gravitational Wave Telescope)
