Результат исследования: Научные публикации в периодических изданияхстатья по материалам конференции


Features of the formation of supersonic underexpanded jets in condensation, as well as measurements in such jets by electron-beam and molecular-beam methods are considered. It is shown that the clusters in the flow can change both the geometry and the structure of the supersonic jets. It is determined that the readings of the mass analyzer used as a detector of a narrowly directed molecular beam depend to a large extent on the size of the clusters and the value of the detector's solid angle. The examples which compare the traditional method of mass spectrometry with ionization and a new method ionization by high-voltage electron beam with the subsequent transport of ions to the mass spectrometer detector with its own turned-off ionization block illustrate changes in the detected clusters.
