Popis:	The axial VUV radiation intensity distribution (< 130 nm) of an air glow discharge at pressure 50–530 Pa was obtained by the thermoluminescent method using the CaSO4·Mn thermoluminophor. The regions of maximum intensity of VUV radiation are the near-electrode regions in a wide range of pressures and voltages. The positive column of a glow discharge is also an area of intense VUV radiation at high-voltage. The formation of thin layer of luminescent defects on the faces of planar lithium fluoride crystals located in the positive column and Faraday dark space of a glow gas discharge was studied. By using a MicroTime 200 time resolution laser confocal scanning luminescence microscope (PicoQuant Gmbh) it was shown that the highest concentration of luminescent defects corresponds to the sides of the crystals that were irradiated near the electrodes.
