Alcator C-Mod Weekly Highlights
July 6, 1998



Engineering:


Work continues on the TF refurbishment. Cleanup of the lower
TF core has been completed, and all sliding joint bare metal
surfaces on the TF magnet are ready for plating. The contractor hired to do
the plating arrived onsite last week and has plated one of our test joints
successfully. We are checking out details with the contractor on the testing
procedure to follow as the plating proceeds. Electroforming of the core
finger joint will also begin this week. Inductive heating solder tests look
very good. We are continuing tests this week to better quantify the process.
Fixturing needed to position the feltmetal pads with more precision is
being fabricated.
New TF bus work for the full scale, full current joint tests is
going into position. Bracing material for the bus is in house and will be
installed following a review of the design.
We continued to make progress in development of the DNB for C-Mod.
The arc supply, the four filament supplies, and the bias snubber supplies were
successfully tested by pulsing them into dummy loads located in the power
area. Work continued on installation of safety equipment, documentation,
and master control logic wiring modifications.
The new ECE radiometer diagnostic being developed by Texas, Auburn,
and MIT showed significant progress over the past month. The design of the
vacuum flange is now complete, and the crystalline quartz vacuum windows are
undergoing vacuum test. The 2-22 GHz amps for the IF section are complete
and within the required specs. Waveguides external to the vacuum system
have been completed and their losses measured.


Travel and Visits:

Rejean Boivin, Ian Hutchinson, Miklos Porkolab, and Steve
Wukitch attended the EPS meeting last week. Josh Stillerman and Tom Fredian
attended a workshop associated with the meeting entitled "Workshop on Remote
Participation in Fusion Experiments", sponsored by the Remote Participation
Working Group of the IAEA Fusion Power Coordinating Committee. Josh Stillerman
presented an invited talk on the remote data access capabilities of the
MDSplus data system.
