J2 - Proc. of MEDSI2018, Paris, France, 25-29 June 2018 C1 - Paris, France T2 - Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation T3 - 10 LA - english AB - The Photon Factory in the KEK has been operating two SR sources, the PF-ring and the PF-AR for over thirty years. Although even now the 2 rings are used extensively in the wide science fields, the aging problems are quite critical so that we started considering the upgrades of the rings and a new SR facility. Assuming an extremely low-emittance storage ring, we are studying in 5 items, beamline optics design, vibration reduction, heat-load management, beam control and beamline vacuum. In particular, the vibration reduction and heat-load management are quite important issues and we are antecedently conducting necessary R&Ds of the beamline and the related facilities, first mirror heat-load management with test chamber, vibration evaluation with fine encoder, development of the phase separator for stable nitrogen supply and the development of the GRIDCOP direct-cooling mirror system. Here, we will introduce our R&Ds. PB - JACoW Publishing CP - Geneva, Switzerland ER -
