✦ Synopsis

The liquefier was designed for 900 m3(n.t.p.)/h of compressed hydrogen, but the smaller quantity during testing was due to the smaller output of the compressors than nominal. Calculations made on the basis of the test results show that the liquefier can be boosted to 1 500 m3(n.t.p.)/h high pressure hydrogen, which will increase its output to 460 1./h normal hydrogen and 280 l./h parahydrogen. It would then be necessary to increase the size of the coil in the atmospheric nitrogen bath and also to increase the volume of catalyst.

The external appearance of the liquefier and the control panel is shown in Figure .

We have measured the resistance and magnetoresistance of commercially produced thick film resistors in the range 80 K-15 mK and in fields up to 20 T. These resistors behave similarly to those produced by another manufacturer and characterized recently by a Japanese group. Between 2.5 and O. 1 K the
