C-MOD Weekly Highlights
March
14, 1996
Alcator C-Mod is now up-to-air, and undergoing safety
checks for diborane,
and neutron activation. In-vessel work will begin as soon as these checks
are
complete. Following the end of the run
campaign on March 1st,
the cryo system was shut down, and the machine was
allowed to warm up to
room temperature.
The vessel was brought up-to-air on March 8th, and a
single point
neutron calibration was performed with a Californium
source inserted
in-vessel.
This maintenance period will be used to make changes to
the outer divertor
support structure, install the cryopump prototype
(which is now in house),
do an extensive alternator inspection, continue
installation of the
new transmitters, and implement selected diagnostic
upgrades. As an ITER
support
activity, we will also collect dust from the machine down to
the 2 micron
level. The dust will be analyzed for
size distribution
and composition.
These issues are of great concern in fusion reactors
where the dust
would be tritiated, and in some cases chemically
reactive.
On
March 6th and 7th talks were given to our newly formed Program
Advisory
Committee on status and plans for C-Mod. Included as part of
the
presentation were talks given by several of our collaborators
on their
current work and near term plans. Panel members able to attend
were
Stewart Prager (University of Wisconsin), Richard
Hazeltine (University of
Texas), David Hill (LLNL), Ted Strait (General
Atomics), Joel Hosea
(PPPL), and Rip Perkins (ITER).
Collaborators
presenting talks were Dave Johnson, Steve Jardin, and
Randy Wilson
(all from PPPL), Ben Welch (University of Maryland), and Bill
Rowan
(University of Texas). John
Willis and Don Priester (OFES), and
Alan Wooten (University of Texas) also
attended.
