Cryogen-free radiation testing!

Princeton Gamma-Tech Instruments has introduced the next-generation of mechanically-cooled  cryogen-free radiation detectors.

The Quiet-One™ is a proprietary PGT design incorporated into their Stirling cryocoolers, that replace liquid nitrogen as the coolant for nuclear and x-ray detectors and provide a smaller footprint and lower power consumption while offering low maintenance and long running life. PGT is the only commercial company in the world able to offer performance for mechanically-cooled nuclear detector that has same performance as liquid-nitrogen cooled.

Industries are now moving away from the use of liquid nitrogen as the coolant for nuclear and x-ray detectors and working with mechanically cooled devices. The main problem is microphonic noise caused by mechanical vibrations which result in peak broadening and poor resolution and results. PGT’s Quiet-One™ anti-microphonic mounting system solves this problem and ensures that there is no reduction in performance when integrated into these cryogen-free units.
