Alcator C-MOD Weekly Highlights
                                August 25,1994

The repair/maintenance period for Alcator C-Mod is continuing. The first
inner coax component has been received. This piece, which is machined from a
single piece of copper, has slots machined into it, using EDM techniques, in
order to provide compliance between the inner and outer conductors.
Preliminary inspection results indicate that the piece is within
specifications and can be used for the OH2L buss, which is the first that must
be installed during the reassembly process. Machining of the inner conductors
for the upper coaxial busses is proceeding.

One recommendation that came out of the engineering review of the buss failure
was that we consider instrumentation to monitor the condition of the
felt-metal joints in the OH busses. Testing on a prototype coil indicates that
this can be done by monitoring the voltage drop across the joint during high
current operation. Instrumentation to accomplish this is being designed into
the replacement coaxes.

Upgrading of the third FMIT power supply, which will be required for the 3'rd
two megawatt ICRF transmitter, has been completed by Uptegraf, and the supply
will be shipped to MIT shortly. This will be used with the PPPL tunable source
and antenna, scheduled for installation in 1996.

This week, Steve Wolfe is attending the ITER Experts Committee meeting on
Confinement and Transport at the San Diego co-center.
