Journal ArticleDOI

TL;DR: The principal current carrier appears to be a high energy (approx 100 keV) electron component, concentrated in the central 20 to 40 cm diameter core of the 80 cm discharge as mentioned in this paper.

TL;DR: The measured loss rate of energetic alpha particles agreed with the approximately 5% losses expected from alpha particles which are born on unconfined orbits.
Journal ArticleDOI
Formation of a 100-kA Tokamak Discharge in the Princeton Large Torus by Lower Hybrid Waves
F. C. Jobes,J. E. Stevens,R.E. Bell,S. Bernabei,A. Cavallo,T. K. Chu,Samuel Cohen,B. Denne,P. C. Efthimion,Einar Hinnov,W. Hooke,J. Hosea,E. Mazzucato,R. McWilliams,R. W. Motley,Szymon Suckewer,G. Taylor,J. Timberlake,S. von Goeler,Robert R. Wilson +19 more
TL;DR: The development of non-inductive current drive is of great importance in establishing the tokamak as a long-pulse or steady-state fusion reactor as discussed by the authors, and lower hybrid waves, carrying 200 kW of power at 800 MHz, have been launched into the Princeton Large Torus tokak to initiate and drive the discharge current to a level in excess of 100 kA.
Journal ArticleDOI

TL;DR: Improvements in confinement associated with the use of tritium and possibly heating of electrons by α-particles are indicated.
Journal ArticleDOI

P. Beiersdorfer,von Goeler S,Manfred Bitter,Einar Hinnov,R. Bell,S. Bernabei,J Felt,K. W. Hill,R. Hulse,J. E. Stevens,Szymon Suckewer,J. Timberlake,A. Wouters,Mau Hsiung Chen,James H. Scofield,Daniel D. Dietrich,Gerassimenko M,Eric H. Silver,R. S. Walling,Peter L. Hagelstein +19 more
TL;DR: Inclusion of electron correlation corrections due to ground-state correlations and (super-) Coster-Kronig-type fluctuations in the theoretical energies is shown to reduce the differences for some but not all types of transitions.
