A mathematical model of the cooling of a continuous-flow cryostat which takes into account real values of the specific and latent heat of the cryogenic fluid and of the specific heat of the cryostat material is presented. The amount of liquid in the cooling fluid and four parasitic heat flows, cause
The design of a continuous flow helium cryostat is described for optical studies with an optical fixed high-pressure chamber in the temperature range from 4 to 300 K. The liquid helium consumption for 4 K is 21 h-', and less than 0.5 1 h-'for temperatures above 20 K.
