Abstract: An electron generating device extracts electrons, through an electron sheath, from plasma produced using RF fields. The electron sheath is located near a grounded ring at one end of a negatively biased conducting surface, which is normally a cylinder. Extracted electrons pass through the grounded ring in the presence of a steady state axial magnetic field. Sufficiently large magnetic fields and/or RF power into the plasma allow for helicon plasma generation. The ion loss area is sufficiently large compared to the electron loss area to allow for total non-ambipolar extraction of all electrons leaving the plasma. Voids in the negatively-biased conducting surface allow the time-varying magnetic fields provided by the antenna to inductively couple to the plasma within the conducting surface. The conducting surface acts as a Faraday shield, which reduces any time-varying electric fields from entering the conductive surface, i.e. blocks capacitive coupling between the antenna and the plasma.

Abstract: A payload delivery and recovery system, having a payload including a data collection device arranged to collect data, and a controllable ascent vehicle comprising a controllable lighter than air (LTA) mechanism detachably coupled to the payload and used during an ascent phase to deliver the payload to a pre-determined altitude. The payload delivery and recovery system also having a controllable descent mechanism releasably attached to the controllable ascent vehicle and that can be used during a descent phase for reducing a rate of descent of the payload subsequent to release of the payload at the pre-determined altitude and including a control system for navigating the payload to a desired ground location during a recovery phase.
