Abstract

We have designed, built and operated two vacuum systems for the RFQ (Radio Frequency Quadrupole) in the APT/LEDA (Accelerator Production of Tritium/Low Energy Demonstration Accelerator) linac: a cryopump system for the RFQ cavity and a non-evaporable getter (NEG) pump system for the RF window system. They were designed to provide very high hydrogen pump speed (>2×10⁴ L/s) and sorption capacity. Both systems underwent performance tests in mock assembly before the installation. This paper presents the mock test results of both vacuum systems. It also discusses the preliminary test results from the commissioning of the APT/LEDA RFQ
