Alcator C-MOD Weekly Highlights June 15, 1994 The Phase II operating campaign is continuing. Most of the operation this week has emphasized single null divertor operation. Experiments on the effect of magnetic geometry on divertor detachment were begun. In addition, oscillating gas puff experiments were carried out to investigate particle transport in the core during divertor detachment. Investigations of 2D neutral density profiles by observations of argon and carbon lines populated by charge exchange recombination with intrinsic neutral deuterium. Experiments were carried out in limited and diverted plasmas. The first pellet injection run of the present campaign is being carried out on Wednesday. The D2 pellet injector is being used to inject one or two pellets into diverted discharges. Long lasting snakes are observed following pellets that reach the q=1 surface. ICRF heating, at powers over 1MW, is carried out after the pellet injection. Indications of ion heating are observed. The Li pellet injector is also being tested near the end of the shot, in preparation for a run next week. An Alcator C-MOD home page (MOSAIC/World Wide Web) can now be reached through the MIT Plasma Fusion Center home page (http://cmod2.pfc.mit.edu/). Information on the C-MOD facility, copies of the weekly highlights reports, pictures of hardware, and data pictures are available through the C-MOD pages. These pages are still being developed, and will be added to in the future. Dick Majeski and Randy Wilson are visiting from PPPL to discuss the upcoming ICRF collaboration. Ian Hutchinson is back, temporarily, from his sabbatical at JET, to get material for his talk at EPS. Three C-MOD papers have been accepted for presentation at the IAEA meeting, covering an overview of the program, divertor results, and transport results, respectively.
