The recently completed AGS Booster is a synchrotron for the acceleration of both protons mass and heavy ions. To minimize the beam loss due to charge exchange of the partially stripped, low β (= v/c), very heavy ions with the residual gas molecules, ultra high vacuum of 10-11 Torr is required for the 200 m Booster ring. An average pressure of mid 10-11 Torr has been achieved and maintained after initial in situ bakes and commissioning. In this paper we describe: (1) design and layout of the vacuum systems; (2) material selection and vacuum processing; (3) PC/PLC based bakeout system; (4) operation of vacuum instrumentation over long cable length; (5) results of bakeout and evaluation; and (6) experience gained during construction and commissioning.
