“…Another way to achieve the maximum parameters of the supersonic outflows into a rarefied medium is downsizing the nozzles and diagnostic tools with the maximum possible increase in the vacuum pumping capacity. The appearance of powerful turbomolecular and closed cycle helium cryogenic pumps provided the next stage in the development of laboratory facilities to create experimental stands PCM [7] and LEMPUS-2 [8].…”

“…During this time, with the financial support of state programs and their own funds, the employees of the department prepared projects of laboratory stands, purchased vacuum chambers, vacuum pumping equipment, and unique measuring instruments. As a result, a complex of experimental stands was assembled, tested and included in the research process [5][6][7][8]. These facilities are used in scientific programs of the Russian Foundation for Basic Research, the Russian Science Foundation, programs * Corresponding author: zarvin@phys.nsu.ru and grants of the Ministry of Education and Science of the Russian Federation, as well as commercial projects.…”

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.
