Magnetically-coupled piston pump for high-purity gas applications

Understand

Experiments based on noble elements such as gaseous or liquid argon or xenon utilize the ionization and scintillation properties of the target materials to detect radiation-induced recoils.

• A requirement for high light and charge yields is to reduce electronegative impurities well below the ppb level.
• To achieve this, the target material is continuously circulated in the gas phase through a purifier and returned to the detector.
• Additionally, the low backgrounds necessary dictate low-Rn-emanation rates from all components that contact the gas.
