Alcator C-MOD Weekly Highlights
			June 25, 1996



	Eight out of ten outer divertor modules have been installed in
the machine.  Work on the remaining modules is complete, and they have
been inspected and approved for installation.  These modules will
be installed as work on the edge Thomson scattering system and the
prototype divertor cryopump is completed.
	All tests of the divertor cryopump in the vacuum test stand are
finished.  The pump is currently installed in the divertor mock-up where
the 300K shield and divertor pressure gauge tubing are undergoing
fitups.
	Work on a variety of engineering and diagnostic systems
continues.   All glow discharge insulators are in house and have begun the
vacuum bake out process.  A full system test will be done in the
vacuum test stand before any components are installed invessel.  All
clamps and spacers needed to install both the glow discharge components
and the diborane manifold have been fabricated and are being cleaned
and electro-polished prior to installation.  An invessel test fitup of the
manifold was completed successfully.  TORVAC wiring is complete and
PLC/PARAGON programming for the new foreline pump is ready to be tested.
The ECE rack has been moved back to the diagnostic stand extension and
new cabling is being installed.  The strain gauge cables have
been installed and the floor and inner divertor modules and tiles over
the gauges and cables have been re-installed.  The retro-reflector mount
for the tangential interferometer has been fabricated and is being cleaned
and electro-polished.  The LN2 cooling manifold box has been sealed.
	Rapid progress continues on the edge Thomson Scattering system.
The laser beam enclosure in the laser room is complete.  Construction has
started on the final section of the igloo beam enclosure. The interlock
system design is complete and installation has started. The
AFOL/DFOL racks are complete and are being installed. The alignment of the
beam optics has been confirmed invessel.  The alignment of the polychromator
is complete and preparations are being made for its calibration.  Focus tests
of the beam optics are planned for the end of this week or early next
week.
	A quarterly review of the Alcator C-MOD program was held at
MIT on 6/19.  Besides presentations from C-MOD personnel, Bill Rowan of
the University of Texas presented a talk on the DNB and associated
diagnostics Texas is planning to install, and Joel Hosea from PPPL discussed
the MIT/PPPL collaboration.  Rostom Dagazian represented DOE.
	Bob Granetz was at the ANS conference in Reno Nevada and gave an
invited talk on "Design Issues for Tokamak Reactor Divertors".
