Summary

Now liquid cryogen targets are used and constructed for experiments being performed at JINR. These devices are needed to provide physical experiments with nuclei of the lightest elements (?2, D2, 4He) as targets. A cryogenic target is a cylindrical vessel made of polymer film filled with liquid ?2, D2, or 4He. The vacuum vessel for the cryogenic target is made of polyfoam. These solutions are used to reduce interactions of the beam and environmental matter (In case of the metal vessel there are too many irrelevant effects). This paper reviews the development of some liquid cryogen targets constructed at JINR, and gives the physical results obtained in these experiments. This paper describes a method of liquefaction of deuterium and hydrogen by using helium and helium - by helium. It also presents the results of using polymer materials while constructing cryogenic targets and vacuum vessels.
