Abstract
X-ray photon sources are used in research. During the past decade, the technology of the X-ray photon source has grown rapidly. To fulfil demands for an X-ray photon source in Taiwan, the Taiwan Photon Source (TPS), an electron accelerator with the energy of 3 GeV has been constructed with high brilliance and flux. To let the Superconducting radio frequency (SRF) system and cryogenic undulators in TPS to be under stable operation, the cryogenic system is therefore very important. Refrigerant of the TPS cryogenic system is liquid helium, to maintain LHe in its state, temperature has to be maintained below 4.5 K; however to evaporate 1 gram of liquid helium, only 20 Joule is needed. Therefore, the Multi-Channel Line (MCL) has been developed to prevent liquid helium vaporizing. Several mechanical parts have been designed to reduce heat loss and strengthen structure stability. In this paper, assembly of the transfer line and experimental results are discussed.
