Alcator C-MOD Weekly Highlights
		          May 12, 1997



	The vessel bake is now complete and electron cyclotron discharge
cleaning is underway.  The ECDC discharge is also being used to test and
calibrate some of the visible and VUV diagnostics and the omegatron.
A new WEB page is available to display invessel video at:

	http://www.pfc.mit.edu/cmod/inside.html

This wide angle view is updated approximately every 10 seconds, and when
ECDC is operating, shows much of the invessel hardware.  The discharge
moves between the inner and outer wall as the toroidal field is scanned.
	All magnets were cooled down to operating temperature for the
first time last week.  Power tests were performed on all supplies,
and several small problems have been found and fixed, or are being
debugged.  Hybrid control of the supplies has been demonstrated and is being
used to control the supplies during the tests.
	All hi-potting of the RF systems is complete.  A final safety
inspection of the hi-yard was done today, and 13.8 kV power
has  been applied to the transmitters for the first time.  A problem with
the new dummy load has been debugged and fixed.  The new coax is
nearly ready for leak checks.
	Dr. Hyeon-Gon Lee visited last week from Korea to discuss core
Thomson scattering with Dmitri Mossessian, and diagnostics in general.
Boris Grek, Dave Johnson, and Joe Bartolick from PPPL were here working on
the X-point Thomson scattering. Chris Brunkhorst also from PPPL was here
helping out with the new RF systems.  Rick Maqueda from LANL is visiting
working on the new IR periscope.
	Martin Greenwald was in Los Angeles last week for an ESNET meeting.
