Alcator C-MOD Weekly Highlights
			Aug. 15, 1995

The scheduled maintenance period continued on ALcator C-MOD last week. Good
progress toward readying the facility for the fall operating campaign
continues. 

Tile cleaning, module assembly, and staking of tile holddowns is going
well. Fit-up and re-installation of tile modules is proceeding.

The E-port ICRF antenna backplane is back in the machine. E-port horizontal
flange has now been reinstalled.

The gas feed flange for the boronization system has been installed, and
fabrication of the gas system is underway. 

Work is proceeding on the EF4 supplies, including connection of the new bus
work and cleanup of the converter cabinets and transformers returned from
Livermore.   

The CO2 laser for the Two-Color Interferometer (TCI) arrived back from the
vendor. This is a sealed laser which had been sent out for re-charging
following completion of the last campaign. 

The optics head for the edge Thomson scattering system was found to be leaking
following the final welding procedure in New Jersey.  Laser welding to seal up
the leaks is being carried out at a local shop. The in-vessel mounting bracket
for this module has been successfully fitted up in the machine. 

New windows were installed for a prototype frequency-doubled YAG
interferometer, which will be installed for density measurements along a
tangential path at the midplane.  

Steve Golovato was at GA last week to participate in the DIII-D experiments to
match C-MOD dimensionless parameters for a test of the validity of
dimensionally similar scaling studies. The corresponding C-MOD experiments
were carried out in May, and the DIII-D run attempted to match the C-MOD
dimensionless parameters as well as possible. Power scans were carried out
using both NBI and RF heating which should provide a good comparison with
C-MOD data.
