RFQ (Radio Frequency Quadruple) accelerator of ISAC (Isotope Separator and ACcelerator) at Triumf has been in full operation since 1999. The RFQ accelerator is a split ring 4-rod structure, 8m long with a bore radius of 7.5 mm operating at 35.36 MHz placed into diagonally split rectangular vacuum tank with dimensions of 1 x 1 x 8 m. The tank's main seal consists of two circumferential Viton O-rings with differential pumping of the space between them. There are six 1000 L/s turbo pumps operating continuously to keep the vacuum in the tank at about 5.0E-7 Torr, measured by two hot filament ion gauges. The gauges are also used for interlocks. This paper describes the details of the vacuum system of RFQ and its operation.
