“…2). A detailed description of LEMPUS is given in [6,11]. This unit was used for testing the regimes of pulsed outflow of clustered flows, pulsed molecular beam measurements, and recording mass spectra with a quadrupole mass spectrometer operating in continuous and pulsed modes consistent with the regimes of gas outflow.…”

A review of the experimental work carried out on the vacuum gas-dynamic stands of the Applied Physics Department of the Novosibirsk State University is presented. Creation of these stands meeting the world’s requirements and equipped with modern diagnostic methods was based on the background experience from the Institute of Thermophysics of the Siberian Branch of the Russian Academy of Sciences under the guidance of A.K. Rebrov. A brief description of the stands and the results of some studies is given. Despite the limited possibilities of the university environment, the use of compact laboratory vacuum stands provides large-scale studies in various areas of rarefied gas dynamics.

The results of the study of processes occurring in supersonic flows of gas mixtures under the influence of high voltage electron beam are presented. The research was performed on the gas-dynamic complex of experimental installations located in the Department of Applied Physics of Novosibirsk State University. Spectral methods and molecular beam mass spectrometry were used to diagnose the processes. A significant difference in the clustered argon mass spectra was found in comparison of spectrum recorded during ionization by a quadrupole mass spectrometer own ionizer and spectrum obtained with the transport of ions formed by an electron beam in the jet through a skimmer to the mass spectrometer detector (without using an ionizer of spectrometer). The second variant of gas flow ionization presents the possibility of registering the mass spectrum of a hydrocarbon series with features indicating the occurrence of heavier hydrocarbons in the jet. The mechanism of intracluster energy exchange with the transfer of excitation initiated by electrons with subsequent intense radiation at certain wavelengths of a neutral argon atom was detected and identified.
