National Synchrotron Radiation Research Center (NSRRC) in Taiwan has initialized the construction of Taiwan Photon Source (TPS) synchrotron accelerator project. This 3 GeV, 500 mA beam current third-generation synchrotron accelerator will have a total of seven insertion device beam lines at day 1 after commissioning. That is, there will be one 2 × EPU48, five IU22 and one U5 undulator beamline. Corresponding front end components such as fixed masks, photon beam position monitor, photon absorber, slits and heavy metal shutter have been designed; manufacturing of these subsystems are on the way. Several prototype assemblies are completed, tested and will be reported in this paper.
