Laser–induced photo-detachment diagnostic for interrogating pulsed ECR–driven plasmas: Application to H$^−$ and D$^−$ negative ions

Résumé

The present work is devoted to an experimental setup tailored to study time-resolved processes relative to negative ion formation in ECR-driven plasmas. It refers to a laser-induced electron photo-detachment system synchronized with H2 and D2 ECR-plasmas being sustained by 2.45 GHz bursts in the kHz range. The system is combined with electrostatic probe time-resolved measurements and information is obtained both on the formation path and the yield enhancement of H − and D − negative ions.
