LPT: LINEAR PULSE-TUBE COOLERS
Overview
The LPT 9310 (LPT=Linear Pulse Tube) pulse tube cryocooler is specially developed for applications where the object to be cooled is extremely sensitive to vibrations. The absence of moving parts in the pulse tube cold head diminishes the influence of most of the disturbances at the cooler-detector interface. The pulse tube cryocooler produces and sustains a detector operating temperature of 80 K. The combination of a cold head with no moving parts and the reliable moving magnet flexure bearing compressor guarantees the high reliability of this cooler type.
