Alcator C-MOD Weekly Highlights
				June 23, 1994


	The phase II operating plan continued this week with more
	RF and divertor experiments.  ICRF heating and coupling
	studies continued over an even wider range of plasma currents
	than previously, namely	from 0.4 to 1.0 MA.  In addition, the range
	of the density scan was extended for limited operation.  Scanning
	probe data was obtained during diverted operation both
	during and after the RF pulse in the same shot.  This run
	marked the first time that multiple, single shot probe scans were
	attempted.

	Divertor work was focused on shaping the plasmas and adjusting
	plasma position.  Progress was made in controlling the
	X-point position and the inner and outer gaps. Elongations of up
	to 1.76 were obtained.  Also, Mo and C levels were observed
	to decrease a factor of two in approximately 100 mS as we
	went into diverted operation.

	The hardware and Hybrid software needed for density feedback
	was successfully tested and used during an RF run this week.  
	We can now program a density time history in much the same way we
	program plasma current.

	Earl Marmar presented a paper at the  American Nuclear Society
	meeting in New Orleans this week.  Bruce Lipschultz, Steve
	Wolfe, and Earl Marmar attended the ITER experts meeting in
	Gaithersburg this week.
