摘要：

A current-free double layer in an expanding hydrogen helicon discharge (13.56 MHz) has been discovered by measuring a beam of hydrogen ions at the low potential side of the double layer. The ion beam is supersonic (similar to2.1c(s)) and is detected using a retarding field energy analyzer positioned downstream of the double layer for pressures below a few mTorr and for radio frequency powers up to 1800 W.
