An Ion Source Plasma starting from a cold La B_6 cathode I

概要

• 論文の詳細を見る

• A hydrogen plasma source is produced from a cold hollow LaB_6 cathode which is heated stably within 3 sec by a concentrated pre-discharge below 200V. It should be noted that mis-discharges diffusing to chamber walls and damages of the cathode due to ion bombardments are avoided. Moreover, the plasma source is stable as external electric fields are removed from there.
