ECDC has
been run continuously for several days as we
attempt to reduce the boron
hydride deposits on the outer vessel
wall and divertor cover plates. This process will have
to continue for
several more days, possibly with the addition
of glow discharge cleaning
to speed up the process.
The
HVDC and control cables for ICRF transmitter #3 have been
installed. The primary 13.8 kV cable runs from the
switchgear
to the high voltage power supplies have been started. Layout of
the switchgear control wiring
has started. Work continues on
the
crowbar units for both transmitters.
The new LN2 pump for the cryo system has been checked out
and
is now operational. New LN2
control valves for the TF magnet cooling
are now in house and being
readied for testing. The large
LN2
storage tank has been modified, refilled, and brought
back online. Much improved regulation of the tank
pressure during
filling has been noted.
The alternator inspection continues at a rapid pace. The alternator
rotor has been removed
from the stator. The rotor bore copper
conductor
has been removed and passed inspection. The rotor winding
has passed the hi-pot
inspection, as did the stator. The alternator bearings
and seals have been
removed and inspected. The flywheel
ultrasound
inspection is complete.
GE, the prime contractor for the inspection,
now has crews working
24 hours/day to keep this work on schedule.
On March 23rd approximately 45 graduate students in
science
education from Southern Connecticut State University visited
the
Plasma Fusion Center. A talk on
Alcator C-MOD was given,
followed by a tour of the experiment. Ian Hutchinson, Miklos
Porkolab, Earl
Marmar, and Steve Wolfe were at the Major Facilities
Review and Field Work
Proposal meetings at DOE this week.
Yuichi
Takase is also at DOE attending the Alternate Concepts
meeting.
