Lil' Cryopump Chamber Facility

This test facility consists of a non-magnetic stainless steel chamber approximately 0.6 m in diameter and 1.2 m in length. The chamber is pumped by a single 50 cm diameter cryopump (CVI-TM500) backed by a ~60 L/s mechanical pump. The base pressure of the facility is approximately 10^-4 Pa, as measured by an ionization gauge, uncorrected for xenon. Thruster testing at xenon flow rates of 0.12-0.20 mg/s results in chamber background pressure of approximately 10^-3 Pa.
