The measurement technique and results are presented from studies of the spectral composition of X-ray emission from different regions of micropinch discharge plasma in a low-inductive vacuum spark device. X-ray spectra are measured in the photon energy range of 1–30 keV for the radiation emerging from the plasma spot, near-anode plasma, and anode regions of the micropinch discharge plasma. It is experimentally established that, in the energy range under study, the intensity of X-ray emission from the plasma spot exceeds that from the near-anode and anode regions.
The measurement technique and results are presented from studies of the X-ray spectra and X-ray yield from micropinch discharge plasma in a low-inductive vacuum spark device at different polarities of the discharge electrodes. The measurements were performed using the specially designed diagnostic system based on thermoluminescent and scintillation detectors. This made it possible to perform measurements in the photon energy range of 1–300 keV.
A single-channel compact (ø5 × 10 mm) noise-immune spectrometer has been developed for measuring X-ray spectra of micropinch-discharge plasma in the energy range of 1−25 keV using the filter method. The spectrometer is based on an array of lithium fluoride LiF thermoluminescent detectors placed in series, which are also used as filters for X-ray spectrum selection.
We analyzed the possibility of using different detector types (semiconductor, scintillator, thermoluminescent, nuclear emulsions) for plasma diagnostics. We investigated the main characteristics of such detectors, on the basis of which an X-ray spectrometer complex was created.
In this paper we studied the non-self mode of the auto-oscillation secondary- emission discharge (ASED) in a longitudinal magnetic field with autonomous electron gun to ignite the primary beam-plasma discharge (PPD).
