A mixture of xenon with a nontoxic halogen carrier Xe–KBr is used to create a plasma radiation source at the 282-nm transition of the XeBr{sup *} molecule excited by a high-voltage pulsed-periodic discharge. The luminescence spectra of the plasma of a longitudinal pulsed-periodic discharge in the Xe–KBr mixture at low pressures are studied experimentally. The most intense UV bands of exciplex XeBr{sup *} molecules are recorded in the spectral range of 250–350 nm. The spectral, temporal, and energetic characteristics of the radiation source are presented, as well as the dependence of the XeBr{sup *} exciplex molecule formation efficiency on the discharge excitation conditions. The optimal conditions for the excitation of UV radiation in the pulsed-periodic discharge plasma are determined.
