By employing double concentric arrays of permanent magnets, a constant field area of about 100 G in a source tube, and a diverging magnetic field near the exit of the plasma source can be generated, where the source consists of a 6.5-cm-diameter glass tube and a double-turn rf loop antenna. The 13.56 MHz rf power is maintained at 250 W and the operating argon gas pressure can be changed from about 0.3 - 2.5 mTorr. Ion energy distribution function is measured by a combination of a retarding field energy analyzer and a pulsed probe technique. As a result, it is found that the beam energy can be increased up to about 40 eV with a decrease in the operating gas pressure., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064669009, レポート番号: JAXA-RR-09-003},
