Alcator C-MOD Weekly Highlights May 5, 1997 Work on the new transmitters continues. The Hi-yard work has been inspected and is ready for testing. The new crowbar systems have been hi-potted to 38kV with the ignitrons installed and are also ready for testing. Cabling for antenna and coax diagnostics has been installed between the power room and the cell. Components are being ordered and fabricated for supporting the new EF4 reactors and bus work so that installation can begin as soon as the reactors arrive onsite. The CAMAC hardware and software for the power systems has been upgraded and has been tested. The leak on the D-port horizontal flange has been found and fixed to a level acceptable for operation. A much smaller leak on C-port horizontal was also fixed. We are now preparing for several days of baking at 130C followed by electron cyclotron discharge cleaning. The DNB test lab is being finished up with a new exhaust fan installation and new paint. Access holes for the DNB transmission lines have also been installed. The as-built drawing of the Faraday cage has been completed and we can now begin work on modifications needed for its installation on C-Mod. The tube socket for the Mod/Reg tube has been cleaned and the tube has been installed. Wiring of the tube has begun. A preliminary design of the high voltage transmission line is complete. A new set of invessel survey images is available on the WEB at: http://www.pfc.mit.edu/cgi/cmod_images?name=invessel/ with prefixes of "survey". These pictures will be very useful as new diagnostics and invessel installations are planned. Bob Granetz and Paul Bonoli were at the Sherwood meeting in Madison, Wisconsin last week. Bob Granetz gave an invited review talk ,"Disruptions in Tokamaks", at the meeting.
