• The ion heating process of a kilovolt plasma obtained by a rapid magneticcompression is studied experimentally. The initial plasma for compression is producedby the encounter of two deuterium plasma streams. For the spectroscopic evaluation ofthe ion temperature, a small quantity of helium is added to the deuterium gas.According to time-resolved measurements of Doppler profiles of a Hell line, the tonheating process is divided into two stages: phase I up to 240 ns from the ignition of thecompression and phase IN hereafter. In phase I, most of measured Doppler profiles takethe Gaussian forms and the heating rate is 1 -2 eV/ns. In phase II, each profile from250 ns to 500 ns shows a two-temperature distribution. The ion temperature is 1.7 keVat 700 ns and the heating rate is 4 eV/ns around this time. Finally, the ton temperaturereaches 3 -4 keV.
