Alcator C-MOD Weekly Highlights
				June 9, 1994
 
The Phase II Operating Campaign is continuing. The main emphasis this week
has been on ICRF heating experiments, and divertor discharge development.
 
Analysis of the ICRF heating results indicate that the energy confinement is
consistent with L-mode scaling over the range of density and currents
studied so far (600 to 800 kA plasma currents, 0.5 to 1.35 X 10^20 m^-3 plasma
densities, with up to 2.7 MW of input power).  

Significant progress was made on developing stable single-null divertor
plasmas with elongations of up to 1.65 .  The new capillary gas injection
system was brought on line and partially detached plasmas were produced.
We are now getting data from two MIT divertor gauges which will allow
comparison of neutral gas compression in open and closed divertor modules.

The neutral particle analyzer is nearing completion. Subsystems,
which include water cooling, CAMAC support, High Voltage connections,
data acquisition, gas system and vacuum are now operational. Final
calibration and interconnections are underway, which include proper
interlock between PLC, magnet control, detector operation (micro-channel
plates) and gas system. After bringing the systems (especially high voltage
and magnet current) to specifications (expected during first week of June),
the examinations of background and detector calibration will be undertaken.


Miklos Porkolab was at PPPL this week reviewing graduate education.
Earl Marmar was also at PPPL at a TFTR program planning meeting.
