	The Taiwan Photon Source is a 3 GeV, 3rd generation synchrotron radiation source at the NSRRC.

The total power and power distri-bution on Front End components is calculated and ana-lysed and Finite Element Analysis is used to verify the thermal performance under high heat loads while Monte-Carlo methods are utilized to simulate the vacuum pres-sure distribution. All apertures of the components are the same to simplify and standardize the design of the Front Ends. This paper describes main design considerations, especially the high heat load and vacuum pressure distri-bution.

A maintenance procedure without baking in situ has been successfully developed and applied to maintain and upgrade the TPS storage ring vacuum system to shorten the machine downtime. The data of photon-stimulated desorption(PSD) reveal that no obvious discrepancy between the in-situ baked and the non-in-situ baked vacuum systems. A beam conditioning dose of extent only 11.8 A·h is required to recover rapidly the dynamic pressure of an unbaked vacuum system to its pre-intervention value according to the TPS maintenance experience.
