Cryogenic Equipment and Systems
Terms
  • cryogenics The science and technology applied to the creation of low temperatures (i.e., approaching absolute zero).
  • cryopump A vacuum pump in which pressure is reduced by condensing gases on surfaces cryogenically cooled to about 20 K (liquid hydrogen) or 4 K (liquid helium).
  • cryospectroscopy The spectrographic analysis of matter that is in a cooled state. Generally, a mechanical refrigerator is used to lower the temperature of the sample, allowing isolation and study of the sample and eliminating intermolecular effects.
  • cryostat A device used to maintain near-absolute temperatures for experimental procedures.
