Alcator C-MOD Weekly Highlights
		      March 4, 1997



	All TF upper arms and all but three vertical legs are now installed,
and the installation of spring plates is underway.  Following boroscope
inspections, hi-pots, coil ringing test, and clean up, the cylinder
will be installed later this week.
	Contractors arrived today to move the 100kV power supply from
storage into the power room.  As mentioned last week, this supply will be
used to provide ACCEL voltage for the DNB. Other DNB related work included
more development of mod/reg plans, and addressing issues involving
the crowbar needed for the new supply.  A simulation of the
new supply, mod/reg, and load is being developed so that specifications
for the filter bank can be drawn up.  We also continue to ready the
new DNB lab area where the beamline will be assembled and tested.  A
safety review has been carried out of the new area, and specifications
developed for ventilation, power, and interlocks.  Work on the DNB control
system also continues.
	The power systems group is now focusing its effort on the
TF supply.  Checking this supply is a major activity, just one aspect of
which is the testing of 480 SCR driver boards.
	We continue to make progress on the new transmitters.  All safety
interlocks on transmitter #3  driver cabinet have been tested. Filament
and bias supplies for the IPA, driver, and FPA, on transmitter #3  have been
tested at full voltage but not at full power.  Work continues on the crowbar
trigger circuits and the crowbars themselves.  John Gumbas from PPPL is
visiting this week to help with the installation of the new transmitter
driver units.  PPPL is nearly finished with the coax sections we will
need for the new RF transmission lines.
	One of our LANL collaborators, Dr. R. Maqueda, was here last week to
check on the fabrication and assembly of the IR periscope system that we are
building to specifications supplied by the LANL group.  This new periscope
will view down into the divertor from a vertical port.
	Bruce Lipschultz was in San Diego last week at the DIIID
PAC meeting.  Earl Marmar was in San Diego at the ITER Joint Work Sight for a
meeting on progress in diagnostic development.
