Alcator C-MOD Weekly Highlights
				Sept. 22, 1994

Alcator C-MOD is still in a maintenance/repair period. Reassembly of the
tokamak is continuing according to plan. 

The new OH2L coax buss has been installed and torqued to specification.
Instrumentation to measure the temperature of the contact pad and the voltage
drop across the interface is in place. 

The new coax busses for the OH2U and OH1 are in process. Fabrication of the
contact pads for these coaxes is also well underway. These busses, which
connect to the coils at the top of the stack, should be ready for installation
when required.

Some additional in-vessel work is proceeding. A new set of mounting studs to
hold a third outboard limiter assembly have been installed between F and G
ports. This limiter will reduce the possibility of runaway electron impact on
the E-port ICRF dipole antenna.

Maintenance is also being carried out on the cryogenics system. The LN2 sump
has been opened and inspected. The main sump filter and the filters for the LN2
pump have also been cleaned. 

TRANSP analysis of ICRF-heated discharges from the last run period is
continuing. Results indicate an increase in the electron thermal conductivity
during heating. The energy in the minority (H) tail as calculated by the code
is consistent with the difference between the stored energy inferred from
magnetics and the thermal energy obtained from kinetic profile measurements. A
discussion of some of these results will be presented by Martin Greenwald in a
paper at the IAEA meeting next week.
