Characteristics of high-temperature deuterium plasma in RPI-type devices

The paper presents results of the spectroscopic and corpuscular measurements of pulsed plasma streams generated within the RPI-IBIS experimental device, which was operated with the pure deuterium puffing. Particular attention was paid to time-integrated and time-resolved measurements of selected spectral lines, i.e. Da, Db and Dg, emitted from deuterium discharges. The measurements made possible an assessment of the basic plasma parameters. The achievement of the local thermal equilibrium (LTE) was investigated. Energies of emitted ions, their total numbers, as well emissions of soft X-rays and fusion-produced neutrons vary considerably with a change of gas conditions
