The cooling of single-crystal samples down to 10 K within the Mark VI Eulerian cradle of a neutron four-circle diffractometer has been achieved by means of a two-stage cryorefrigerator fixed to the offset χ circle and coupled to the φ shaft. There is no blind spot for the φ rotation but the χ rotation must be restricted to the −100 < χ < 50° range to avoid collisions of the cryorefrigerator with the detector shielding. The major advantages of this device are its low running cost and its in case of intensive use will rapidly cover the cost of purchase.
