ABSTRACT:
A miniature cryogenic cooling system having low microphonics and thermophonics. The apparatus includes a cold finger incorporating primary and secondary working volumes and their associated regenerative beds. Both volumes are adapted to effect cooling. A displacer reciprocates within the cold finger under the influence of push-pull pressure waves from a dual compressor assembly. The cold finger includes an arrangement for providing pneumatic cushioning of the reciprocating displacer to control displacer slamming.
