A self-designed helicon wave plasma (HWP) source with an internal "right-hand" helical antenna driven by a 13.56MHz radio-frequency (RF) source is investigated for its possible use for processing wall material in future magnetic fusion devices. The plasma beam is ejected into a larger diffusion chamber, where the ion energy distribution and electron energy distribution are measured by commercial...
Plasma Display Panels (PDP), the underlying engine of panel plasma television displays, are being investigated for their utility as radiation detectors called Plasma Panel Sensors (PPS). The PPS a novel variant of a micropattern radiation detector, is intended to be a fast, high resolution detector comprised of an array of plasma discharge cells operating in a hermetically sealed gas mixture. We report...
The excitation of backward waves in the beam tunnel of a high power gyrotron is considered. Such instability is believed to degrade beam quality and consequently gyrotron efficiency. The instability occurs in a region of the beam tunnel where both the magnetic field and beam tunnel radius are strong functions of axial position. The instability can be suppressed by coating the walls of the beam tunnel...
The dynamics of the plasma (Ne, Ar) evolution and hotspots formation has been studied by a PIN detector, a time-resolved and time-integrated MCP soft X-ray pinhole camera, fast optical camera systems and a N2-laser interferometry. Fast streak and framing photos reveal two well-defined compressions with ∼ 60 ns time seperation during the plasma evolution. Cosequently the soft X-ray emission which was...
