Abstract
A hydrogen pump with a capacity of 3.7.104 liters/sec and a built-in liquefier is described. The pump produces a limiting vacuum of the order of 10−8–10−9 mm Hg. The total required power (including the power used in obtaining the liquid hydrogen) is 17 kw, which is less than the power required for an oil-diffusion pump of the same capacity.
