Frost prevention
Hope, H. and Parkin, S.  International Tables for Crystallography (2012). Vol. F, Section 10.1.3.3, p. 245 [ doi:10.1107/97809553602060000827 ]
Frost prevention 10.1.3.3. Frost prevention Three areas must be kept frost-free: the crystal, the crystal mount and the delivery end of the transfer tube. The first successful solution to this problem was the dual-stream design of Post et al. (1951). It provides for a cold stream surrounded by ...

Liquid-helium-based cold gas supply
Hope, H. and Parkin, S.  International Tables for Crystallography (2012). Vol. F, Section 10.1.3.2, pp. 244-245 [ doi:10.1107/97809553602060000827 ]
Liquid-helium-based cold gas supply 10.1.3.2. Liquid-helium-based cold gas supply Open-stream cooling devices that can reach temperatures around 5K are now commercially available. In principle, the design is simpler than that for liquid-nitrogen-based devices. A basic cooling apparatus consists of a liquid-helium transfer line ...

Liquid-nitrogen-based cold gas supply
Hope, H. and Parkin, S.  International Tables for Crystallography (2012). Vol. F, Section 10.1.3.1, p. 244 [ doi:10.1107/97809553602060000827 ]
Liquid-nitrogen-based cold gas supply 10.1.3.1. Liquid-nitrogen-based cold gas supply Historically, two methods were commonly used: generation of gas by boiling liquid N2 with an electrical heater, and cooling of a gas stream in a liquid-N2 heat exchanger. The currently common methods are boiling, and cooling of ...

Principles of cooling equipment
Hope, H. and Parkin, S.  International Tables for Crystallography (2012). Vol. F, Section 10.1.3, pp. 244-245 [ doi:10.1107/97809553602060000827 ]
Principles of cooling equipment 10.1.3. Principles of cooling equipment There are many ways to construct a low-temperature apparatus based on the cold-stream principle that functions well, but they are all made according to a small number of basic principles. All gas-stream crystal-cooling devices must have three essential ...
