E.h. Fritz Klocke,Aaron Kuchieids are very important for low-temperature physics because they are the simplest means of achieving low temperatures. In particular, the properties of liquid helium are essential because all refrigeration methods to T < 10 K use liquid helium as a final or intermediate refrigeration stage. I shall n

E.h. Fritz Klocke,Aaron Kuchiee isotope .He is used instead of the common isotope .He. The main reason is that .He has a substantially larger vapour pressure than .He at the same temperature; the ratio P./P. is 74 at 1 K but about 10. at 0.5 K (Figs. 2.7, 8). A further advantage of using liquid .He instead of liquid .He at tempe
