Alcator C-MOD Weekly Highlights
				Oct 2, 1995

Alcator C-MOD is presently in a scheduled maintenance and upgrade period.
Progress toward readying the machine for the fall operating campaign is
continuing well. Despite the uncertainty in continued funding, in the absence
of Congressional action on the relevant bill, we are endeavoring to maintain
the momentum of the schedule so as to be able to undertake a substantial
experimental  campaign in FY96.

In-vessel installations and alignment activities are on-track for a scheduled
pump-down this week. New fast thermocouples for measurements of divertor
temperature during operation have been installed. New studs for the charged
fusion product detector assembly have been installed and the new shield
completed. Installation of the edge Thomson scattering system is nearly
complete. The divertor gas tubes have been installed. Repairs to two damaged
flux loops have been completed.

Work on the new EF4 supply is well along, and this supply is expected to be
operational when we resume operation. The stress cones have been installed and
the 13.8kV AC cables hi-potted. The transformer is being baked out in
preparation for hi-pot testing. Control wiring is complete and under test.
4160 VAC has been connected for preliminary power testing into a resistive
load. Fault enunciation and actions have been tested. PLC logic for this
supply has been completed and is under test; the PARAGON control screen is
near completion. 

The Bragg cell driver for the new tangential interferometer system is now
operational.

The 13.8kV breaker/disconnect for ICRF transmitter #3 is in-house. The old
step/start house has been removed from the high-yard to make room for the
new disconnects for units #3 and 4.

Our collaborators from the Johns Hopkins University (Mark May) and the
Univ. of Maryland (Ben Welch and Jim Weaver) visited last week to
install diagnostics and discuss future experiments on C-MOD. The JHU
"moly monitor" spectroscopic diagnostic has been reinstalled on the
machine. The Univ. of Md. collaborators brought and installed a new, high 
resolution, 2d visible-UV spectrograph. Jim Weaver will remain at C-MOD to 
operate it. Alan Wan and Juan Moreno of LLNL visited to discuss collaboration
in modelling radiation transfer of hydrogen light in the divertor. 

Dr. Yuri Gribov, Group Leader of the ITER Plasma Equilibrium and Control Group,
Plasma and Field Control Division (Naka Joint Work Site), visited C-MOD last
week for detailed discussions regarding plasma startup and control issues.
Several possible experiments on C-MOD which could be used to validate ITER
scenarios and modeling were discussed. 

Dr. Gunter Janeschitz, Leader of the ITER Divertor Group (Garching Joint Work
Site) also visited C-MOD last week. Discussions included recent C-MOD results
and plans for future ITER-relevant experiments. Dr. Janeschitz also presented
a seminar on the "Status of ITER".
