Abstract

Large Scale Research Facility such as J-PARC is faced on a budgetary deficit and also environmental concerns. Then, affordable and sustainable energy supply should be considered to continue and develop the big science. Magnets of the synchrotron are excited by a pulse operation power supply, and then the load fluctuation should be a severe problem. An energy storage system, such as superconducting magnetic energy storage (SMES), flywheel generator so far are expected to protect the load fluctuation and the instantaneous voltage drop. The author has investigated about the application to the particle accelerator power supply of SMES. The resent status and the future energy storage systems for large-scale research facilities, especially a particle accelerator facility, are described in this paper. This engineering technique is effective for office buildings and hospitals so far. Feasibility of the sustainable energy supply will be discussed.
