**** Exerpts from the U.S. Congress Office of Technology Assment report on TPX and Alternate Concepts.
**** Edge transport and turbulence studies on U-3M
The turbulent-driven particle flow is shown to be comparable with the equilibrium flow at the boundary of the configuration under Alfven-heating conditions in the U-3M torsatron.
**** Topological aspects of island divertor studies on W7-AS
The structure of the edge plasma in W7-AS, observed with probes, television camera, and H-alpha light agrees at low beta with vacuum field calculations: the low-valued resonances at iotabar=5/m are resolved for m = 8 to 11; external perturbations are not significant at the edge, even for iotabar = 5/10.
**** 140-GHz second harmonic O-mode electron cyclotron heating at W7-AS
First experimental results are presented of 140-GHz second harmonic O-mode (0.7-MW power) ECRH at a high electron density of 1.8 x 10^20 m^-3 on W7-AS.
**** Equilibrium plasma currents in quasi-symmetric stellarators with a helical magnetic axis
The plasma currents in quasi-symmetric stellarators are calculated to determe the quasi-symmetric conditions with the help of analytical equations.
