Abstract :
A prototype of the INS accelerator system was constructed to produce an intense dc beam of protons at energies up to 200 keV. Using a Pierce geometry accelerating system, a 250-mA dc beam of hydrogen ions was extracted at an energy of 125 keV from an annular duoplasmatron. Of this beam, 100 mA of H+ ions were transported into a l-cm-diam supersonic jet target, with backstreaming gas minimized by differential pumping. Both the jet target and the differential pumping system functioned satisfactorily. No substantial increase in backstreaming of the nitrogen jet gas occurred for a beam power equivalent to 150 kW of tritons onto deuterium.
