Mj. Hardie et al., AN OPEN-FLOW HELIUM CRYOSTAT FOR SINGLE-CRYSTAL X-RAY-DIFFRACTION EXPERIMENTS, Journal of applied crystallography, 31, 1998, pp. 815-817
An open-flow helium cryostat for single-crystal X-ray diffraction expe
riments capable of reaching 14 K has been developed using off-the-shel
f components. Solid/liquid air build-up is prevented using the transfe
r-line helium back-flow and a heated nozzle. The system has run for ov
er 30 h with no frost build-up.dagger The effectiveness of the system
has been demonstrated using test data for oxalic acid, terbium vanadat
e and dysprosium vanadate.
