On the peculiarities of radial temperature distribution in the channel of pulsed discharge in water at the relaxation stage

The results of measurements of the radial temperature distribution of pulsed discharges in water are reported. The data obtained concern the relaxation stage for discharges with small inductances of the discharge circuit and the active stage for discharges characteristic of pulsed discharge installations. A number of corrections, which are typical of the radiation emission of nonhomogeneous, optically thick plasmas and take into account the features of the radiation output from a cylindrical plasma channel located in a liquid, have been made
