Alcator C-MOD Weekly Highlights
Sept. 29, 1994

The maintenance/repair period is continuing. Excellent progress was made on
the tokamak re-assembly this week.

Following final installation of the OH2L coax, the lower wedge plate was
raised into position and aligned. The twenty lower TF radial arms were then
installed. The spring plates, which maintain compression on the feltmetal
sliding joints, were installed at the inner joints of all the lower TF arms.

Following inspection and testing, including turn-to-turn hi-pot of the TF
arms, final preparations were made for transferring the tokamak from the
assembly stand back to its permanent location on the lower dome. The "big
lift", which is one of the major activities in the re-assembly process, was
successfully carried out on the morning of Tuesday, September 27.

The assembly stand has now been dismantled, and the Southeast section of the
diagnostic stand, which had been removed to accommodate it, has been
re-assembled.

The next step in the assembly process is installation of the OH1 and OH2U
coaxes, which connect to the top of the core. Fit-up of these components is in
progress.

Manned access to the vessel has been re-established, and installation of a new
set of magnetic diagnostic loops (partial rogowskis) on the inner wall is
proceeding. These loops will be used to help determine the distribution of
poloidal halo currents on the inner wall during disruptions.

Checkout of the cryogenic system has begun. The LN2 sump has been re-sealed.
All lines are being checked for cleanliness. GN2 flowrate through the
proportional valves are being checked, and closing of the valves verified. All
pressure transducers are being tested.

Miklos Porkolab, Martin Greenwald, and Jim Terry are attending the IAEA
meeting in Sevilla, Spain, where they are presenting papers on Alcator C-MOD
results.
