The Taiwan Photon Source (TPS) is a 3-GeV third-generation source of synchrotron radiation with beam current 500 mA stored in the storage ring. A front end allows intense synchrotron light generated in the storage ring to pass through to a beamline. Most heat load of the synchrotron light is removed in the front ends to protect the beamline components. Alignment of front-end components becomes important to prevent damage from the large heat load. Because of the many front ends and the brief period of installation, the alignment work should be easy, quick and reliable. Using a shim method, the adjustable degrees of freedom are decreased from six to two. This adjustment work becomes easier and quicker. The alignment of a front-end prototype is described here.

Safety interlock is one of critical subsystems in synchrotron radiation accelerator. A front end (FE) interlock prototype system has been designed, fabricated, and initially tested for Taiwan Photon Source (TPS). TPS FE interlock logic is designed based on that of Taiwan Light Source (TLS), and moderately modified due to the accelerator parameter discrepancy between TPS and TLS. The programmable automation controllers (PAC) have been utilized in FE safety interlock system for their reliability, convenience, processing capability, communication, and stability in user interface. In FE PAC system, touch panels are used as the graphical user interface (GUI) to control and monitor FE components. In addition, with GUI control it is used to beam position monitoring devices as well as confined beam sizes aperture for beam line users. The interlock design such as data acquisition and parameters monitoring for vacuum pressure, flow rate of cooling water, pressure of compressive air, chamber and water temperature, and overall interlock logic are also presented in this paper.

Vacuum system for the 3 GeV Taiwan Photon Source (TPS) has been started the construction since 2010. The critical components such as the bellows and gate valves with rf-contact shielding, pulsed magnet kicker ceramic chambers, BPM, crotch absorbers, etc. have been manufactured and tested. Aluminum alloy (Al-) vacuum chambers for the arc-cells have been machined and undergoing the in-house welding. Mass production of the vacuum equipments including the ion gauges, ion pumps, NEG pumps, and gate valves, has been contracted out and partially delivering following the schedule of the cell assembling. Each cell, contains two short Al-straight chambers and two Al-bending chambers, has been started the assembling and on-site welding on the pre-aligned girders in clean room forming an one-piece vacuum vessel about 14 m in length following by the vacuum baking to the ultra-high vacuum. The conceptual design of the vacuum systems for the long straight sections, the concentric booster, and the transport lines, will be addressed. The progress of prototyping development and the status of construction for the TPS vacuum system will be described in this paper.
