Chemical Kinetics of Chlorine in Electron Cyclotron Resonance Plasma Etching of Si

“…The values differ slightly from those given in Ref. [ 1 ] because only ion impact ionization of the plug neutral beam is included here, and a different subroutine is used for this crosssection. Electron impact ionization is negligible.…”

“…Fusion reactor designs based on the tandem mirror concept have been carried out by several groups [1,2]. These designs rely on 200-5 00-keV neutral-hydrogen beams and ECRH heating to maintain the electrostatic potential in the end cell.…”

“…An alternative approach to hydrogen beams in the end plug might be the use of beams of neutral lithium, carbon, oxygen, or other atoms with Z > 3 at energies of 0.5-1 MeV-amu" 1 . Such beams would be produced by the formation* of negative ions of lithium, carbon, or oxygen, acceleration of the negative ions using an RF accelerator, neutralization of the negative ions by one electron loss impact collisions in a thin gas cell or by laser photo-detachment, and injection into the end plug plasma (Fig.…”

Development and application of a formal methodology for the selection of fusion energy options

“…The conceptual TMR requirements for technological feasibility are, ^ =10^^, Tg = 40 KeV, and nT = 2.5 x 10^S-cm"^ (41,42,43). estimated to have a total net electrical production capacity of 1000 MW^ 3 with plasma fusion power density of 5MW/m (45), whereas an improved tan dem mirror can be as small in size as 750 MW^ (42) and 500 MW^ for the TMR's with the thermal barrier (43).…”

“…Good -TMR is predi cated upon steady-state operation which has no unusual requirement for energy storage (43). Also, according to DOE rating (Appendix C) mirror systems energy storage requirment is rated above RFP and below EBT reac tors.…”
