For better performance and more efficient operation of today’s storage ring of electron synchrotron radiation facilities, it is essential to have a good booster vacuum system to start with. The ultrahigh vacuum system for the electron booster ring of the 3GeV Taiwan Photon Source accelerator has been constructed since 2010, and then installed and commissioned since 2014. TPS booster is a 496.8m long stainless steel vacuum system and currently the largest of its kind in the world. Although low impedance consideration is not critical in a booster vacuum system, the tight dimension and other demanding engineering tolerances do show their criticalness in the construction, installation, and commissioning phases. During construction, some of the original ideas have been modified due to these given tight tolerances. It is even more demanding as we found in the commissioning phase and a lot of actions have been taken to make commissioning process possible. The original design, the modifications in both the construction and commissioning phases will be described in this paper.
