To exercise highly sensitive control (testing) over total leakage for rocket-space engineering products, fuel in particular, a new technology was developed. It is based on Ihe forced accumulation of helium, as a test gas, in the volume of a sorption pump for selective vacuum pumping. Ionic plasma (electric arc) small-size pump is used for this purpose.
