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:

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.
