A.; Grebenshchikov, S. E.; Grinchuk, V. A.; Grishina, I. A.; Kolik, L. V.; Larionova, N. F.; Letunov, A. A.; Logvinenko, V. P.; Petrov, A. E.; Pshenichnikov, A. A.; Ryabenko, G. A.; Sarksyan, K. A.; Skvortsova, N. N.; Fedyanin, O. I.; Kharchev, N. K. // Plasma Physics Reports;Jun2005, Vol. 31 Issue 6, p452
After boronization of the vacuum chamber of the L-2M stellarator, radiative losses from ohmically and ECR heated plasmas were reduced by a factor of 3â€“4. Under these conditions, radiative losses in the ECRH regime comprise only 10â€“15% of the input microwave power. Some effects have...

The linear electrostatic dissipative trapped-electron mode is investigated in a quasihelically symmetric (QHS) stellarator and a configuration whose symmetry is spoiled by the addition of a mirror contribution to the magnetic spectrum. The effect of the trapped electrons is accounted for using...

An experimental procedure to investigate the spatiotemporal characteristics of electrons in the vicinity of mean energy in a radiofrequency plasma is proposed by using optical emission and absorption spectroscopy in Ar. The method employs optical kinetics of long-lived metastable atom Ar(1s5)...

- Two-dimensional fast reconnection in a fluid drift model. Scott, Bruce; Porcelli, Franco // Physics of Plasmas;Dec2004, Vol. 11 Issue 12, p5468
A simple scenario for two-dimensional reconnection is reexamined in the context of a fluid drift model which treats the pressure and parallel ion velocity independently. The rapid nonlinear establishment of an arbitrarily thin current sheet is unaffected for expected values of the plasma Î² of...
