  The construction of the Taiwan Photon Source (TPS) storage ring is under way, to be completed in mid 2012. The new helium cryogenic system is provided from the Linde Company, to be installed after the TPS storage ring is completed. The super conducting radio frequency (SRF) cavities is needed to maintain the electron energy of storage ring and were operated at refrigeration mode such that the cold helium gas from the cavity cryostat is returned to the refrigerator. One distribution valve box and individual segments of multichannel transfer lines is required to supply the liquid helium and liquid nitrogen to the SRF cavities and recover the gas helium and gas nitrogen back to the cryogenic system. This paper is aimed to present the configuration and design features of the LHe transfer system. The heat load and pressure drop calculation of the transfer system was also presented.

  The accelerator complex of the Taiwan Photon Source (TPS) consists of two 500-MHz RF systems: one RF system with KEKB-type single-cell SRF modules is used for the 3-GeV storage ring of circumference 518 m, and the other with five-cell Petra cavities at room temperature is for the concentric full-energy booster synchrotron. This overview of the construction of the 500-MHz RF systems for the TPS is presented with emphasis on our strategy to approach the expectation of highly reliable SRF operation of the TPS. How to complete the construction project on time, on budget and on performance is our unique concern.
