The utility model relates to analytical instrument making, in particular to the discharge VUV lamps used as a source of ionisation in gases analyzed photoionization detectors. Proposed discharge VUV lamp, comprising a sealed cylindrical glass housing (1) filled with an inert gas or a mixture of inert gas under reduced pressure box (2) to output the EUV radiation, means for creating a glow discharge inside the housing (1) of the lamp and extending from housing (1) terminals (5) and (6) for connection to a source (7) of the electric power, in which according to the utility model between the window (2) and the end of the housing (1), a gasket (8) of ceramic material projecting beyond the dimensions housing (1) having a p In Central part of the opening (9) and the outwardly facing annular projection (10) on which is fixed a window (2) to output the EUV radiation. The technical result consists in eliminating cracking of the window (2) of the lamp due to the difference in the coefficients of linear thermal expansion of the material of the window (2) (MgF 2) and the glass body (1). 3 zav.p. f-ly 1 Fig.
