ON THE VUV RADIATION OF TOWNSEND AVALANCHES

Gas scintillation counters of radiation intensiuvely developed in last years, are advanced compared to proportional gas counters by their enhansed energy resolution [1] In such a counters there is registered VUV radiation of the Townsend avalanches (A) in contrast to charge collecting in the conventional counters. This work concerns the study of the VUV spectra of A in rare gases and H2 at pressures P=0.1-30 atm

ON THE INLFUENCE OF ELECTRODES ON THE PROPERTIES OF HIGH PRESSURE DISCHARGE

It is known, that in the nearelectrode regions of low pressure arcs there occur a lot of exotic phenomena [1]. As for the high pressure discharges, the information about the electrode phenomena is very scanty because the intensity of visible, emission is usually comparable to the radiation of nearelectrode regions

ON IONIZATION INSTABILITIES OF HIGH PRESSURE DISCHARGES

Recently there was discovered an instability of high pressure discharges [1-3] but the mechanism of such instability has not been studied. This report is devoted to the experimental investigation of the instability in direct current arcs and in HF discharges [4] in H2, D2 and rare gases at pressures up to P=30 atm
