Split pulse tube cryocooler with innovative double-piston linear compressor.

Author(s) : KAISER G., ALBERT S., SCHMIDT J., et al.

Summary

A split pulse tube cryocooler with double-piston linear compressor is developed. The compressor is driven via an innovative electro-dynamic linear motor operating by using a moving coil and core principle. This new development offers several advantages compared to moving coil or moving magnet systems. It is possible to generate higher forces, power and efficiency like in the case of moving coil systems. The reluctance force of the magnetic system can be used as a substitute for mechanical springs. This way, the average position of the mover is assured as for moving magnet systems. After an introduction describing the new driving principle, the authors present the theoretical and experimental results.
