All right reserved.The main results of the work are as follows: - When a hydrogen plasma flow interacts with a supersonic gas jet of nitrogen or neon (the maximum density in the gas jet reached 1017cm-3), a plasma layer ≈ 3÷4 cm thick for ≈2÷3 μs is formed, which emits soft X-ray radiation. The displacement velocity in the direction of the plasma flow is ≈ 3×106cm/s. Such a high speed of the radiation source movement under one-sided action on a gas jet puts forward certain requirements for the synchronization of counter-propagating plasma flows in the current experiments on two-sided action on a gas jet. - Line emission spectra of multiply charged ions recorded during the interaction of hydrogen plasma flows with jets of nitrogen or neon made it possible to estimate the electron temperature of the plasma formed in these experiments, which in both cases turned out to be at the level of 40 ± 10 eV. However, it should be noted that observed intense resonance Ne VIII lines can be emitted by a plasma only at a temperature of 70÷100 eV.
