Abstract
Investigation of liquid helium-4 by neutrons scattering methods demand s special cryogenic equipment. The experimental conditions require a p rolonged exhibition of the large liquid helium sample. Besides, helium -4 is one of the difficult subjects for cooling, as it possesses high heat content, the thermal capacity peak in lambda-point, and the therm al conductivity in the superfluid state. A cryostat for the inelastic neutron scattering research is described. Cryostat permit to operate w ith the large liquid helium sample (2600cm(3)) at the temperature rang e 5.2 - 1.2K and pressure up to 30 bars.
