   The results of the experimental research of process of formation and contragire of the volumetric discharge (VD) in helium are given by pressure about atmospheric, initiated by UV-radiation for the various initial conditions of its ignition. The spectra of radiation both for volumetric and contragiral discharges for various materials of electrodes are investigated, and also with application of EOT (Electrooptical transducer) shooting; the results explaining both features of formation cathode spots, and character contragire of VD in the spark channel are received at various ways of creation of initial concentration of electrons.
