Alcator C-MOD Weekly Highlights
		      December 17, 1996



	All tests of the OH coaxes required before installation have
been completed successfully.  Work continues on the fitup and installation
of cover plates for the lower TF arms, and we are nearing completion of the
the cleanup work on the upper arms.  Work on new diagnostics for the OH
stack continues.
	Dust collected from the vessel with a 2 um filter has been analyzed
by the Materials Science and Technology Group at the PFC.  A SEM-EDX
analysis of the dust indicated most particles were made up of molybdenum,
with small amounts of Si, Fe, Ti, Cr, Cu, and Ag also found.  The average
particle size found was 72.5 um^2.  Analysis is continuing with SEM
photographic documentation.  This project is an ITER support activity.
	We continue to work on the layout of the DNB beamline test stand.
Power distribution to the DNB power supplies is almost complete, and we will
soon be ready to begin testing the supplies.  
	Assembly of the crowbar trigger circuits for the new transmitters
is complete as are all control and fault detection boards.  The new
switchgear control wiring is ready for testing.  We have begun to setup the
new RF control equipment in the C-Mod control room.  Fiber and cable runs
from the control room to the power room are also being layed out.
	A new nitrogen manifold to supply purge gas for diagnostic applications
has been fabricated and is ready for installation.  Work continues on
invessel diagnostics including the new tangentially viewing XUV arrays,
rearrangement of gas capillaries, calibration of MHD coils, tests of
strain gauges, and repair of divertor probe arrays.  Work on the tangential
two-color interferometer, new periscope designs, new fast scanning
gas injection probe, and relocation of some diagnostics in preparation
for DNB installation is moving forward.
	Raffi Nazikian from PPPL visited this week to discuss possible
collaboration on C-Mod.  New hardware to be added to the C-Mod reflectometer
is being discussed, particularly additions to enhance fluctuation
measurements, as are upgrades to the existing hardware.
	Joe Snipes attended the Feedback Stabilization Experiment
Workshop at PPPL last week.
