A unit for holding and centring a closed‐cycle refrigerator on an Eulerian cradle is described. The X, Y translations orthogonal to the ϕ rotation are obtained by tilting motions, and blocked by a constant springload. Locking is therefore not necessary, and this facilitates the centring of the crystal. In addition, the unit is very easy and cheap to fabricate. The cryostat is in routine operation for neutron diffraction work, and a similar design should be applicable in X‐ray diffractometry.
