Contribution
It presents a novel pump design using magnetic drive and polymer gaskets suitable for ultra-clean, high-pressure xenon gas recirculation in sensitive physics experiments.
Findings
Capable of pumping over 16 SLPM of xenon gas
Operates effectively at 750 torr differential pressure
Meets extreme purity and containment requirements
Abstract
A magnetically driven piston pump for xenon gas recirculation is presented. The pump is designed to satisfy extreme purity and containment requirements, as is appropriate for the recirculation of isotopically enriched xenon through the purification system and large liquid xenon TPC of EXO-200. The pump, using sprung polymer gaskets, is capable of pumping more than 16 standard liters per minute (SLPM) of xenon gas with 750 torr differential pressure.
