  • Radiation effects on insulating gases for the ITER NBI

    1998-10-1The radiation induced leakage current in dry air and SF 6 has been measured as a function of dose rate, voltage, and electrode separation in order to assess the problem for the ITER NBI system insulating gas. The results indicate that for the high voltages involved, the leakage current is a function of the gas volume
