This paper proposes a drive waveform for plasma display panels (PDPs) which have a long discharge gap and use a high Xe-content discharge gas mixture.
According to a long discharge data series, the minimization of water consumption rate is chosen as the objective function, along with several physical and operational constraints.
It was started in 2013 and consists in transforming the Tore Supra tokamak into an X point divertor device, while taking advantage of its long discharge capability.
Thanks to its superconducting magnet which enables potential steady plasma discharges, Tore Supra is the biggest tokamak in the world today capable of facing physics, experimental and technological issues necessary to prepare very long discharge operation of next step devices.
Even high quality online data evaluation, which is essential for the scientific documentation of the experiment, has to be performed automatically due to the huge data sets being recorded in long discharge runs.
The large helical device (LHD) is a superconducting magnet system, created for the performance of plasma-fusion experiments, with an operation time of over a half-year for one cycle and long discharge being one of its main missions.
The WEST (W – for tungsten – Environment in Steady-state Tokamak) project is based on an upgrade of the Tore Supra tokamak, into a double X-point divertor device, while taking advantage of its long discharge capability.
Degradation of the plasma confinement with increasing of the neutral pressure was observed, and that suggested the effective particle control is necessary for the sustaining of long discharge with high performance plasma and the further improvement of the confinement.
Harvard's Aziz says it's the first storage system he's heard of targeting such long discharge durations, other than pumped hydroelectric, and that it appears the company is trying to break new ground on kilowatt-hour pricing as well.
