Time development of a current-free double-layer
The time development of a supersonic (∼2.3Cs) argon ion beam generated by a current-free double-layer (DL) is obtained by pulsing a “helicon” discharge (13.56 MHz) and measuring the total ion current and the ion beam current during the first few milliseconds using a retarding field energy analyzer. The ion beam current is detected during the plasma breakdown phase (60–250 μs) and is stable thereafter (⩾250 μs). Temporal measurements of the floating potential upstream and downstream of the DL...[Show more]
