Alcator C-MOD Weekly Highlights
				March 17, 1994

Good progress has been made this week toward readying the machine for
pump-down and subsequent operation.  

All tile modules are now  installed in-vessel.  Current shunt installation is
now proceeding on the outer divertor modules.  Measurements are also being
made of tile module alignment, now that all modules have been torqued to
specification. Divertor diagnostics continue to be installed and debugged. 
One out of two new Rogowski coils is now in place, and installation of the
second one is proceeding. These new Rogowskis will be used to measure halo
currents flowing in the inner cylinder. Debugging of the divertor
thermocouples and gas system continues.  Calibration of Reticon arrays also
continues.

A-port horizontal was installed this week after a final leak check.  A leak
check of the inner seal still needs to be performed.

All hardware modifications to the cryo system are now complete. The major
change to the cryo system, as mentioned here several weeks ago, is a new
emergency backup system to keep the magnets cool in the event of an LN2 pump
failure while in bake out mode. In addition, several new sensors have been
added to better diagnose both GN2 and LN2 pressures and flow rates throughout
the system.  PLC software for display and control of the new hardware is now
being developed. A formal review of the software/hardware will be required
before operation of the emergency system is implemented.

Installation of the D-port ICRF dipole antenna was completed, including
current straps, and B4C-coated Faraday shield. The backplate, feedthroughs,
and current straps for the second (E-port) dipole antenna have been
installed. Work on installation of the Faraday shield is proceeding. 
	
The 9th IEA ASDEX/DOE Divertor Tokamak Workshop was held at MIT on 14-15
March. The topic of this year's workshop was Disruptions in Divertor Tokamaks.
Participants included representatives from IPP-Garching, CRPP - Lausanne,
Culham, GA (DIII-D), MIT (CMOD), PPPL (PBX-M, TPX), Sandia, ITER JCT (Garching
and San Diego), and ORNL. 

A paper reporting Ohmic H-mode results on Alcator C-MOD, by J. Snipes, et al., 
based on data obtained during the 1993 campaign, has been accepted for
publication by Nuclear Fusion.
