Alcator C-MOD Weekly Highlights December 3, 1996 Tests on the OH2L coax are complete and we are ready to begin work on the OH2U and OH1 coaxes. The force/deflection test of the coax indicated proper operation of the central coax foot, as did a pressure sensitive film test. All TF lower arms have been cleaned and a new layer of epoxy sealer applied. The lower arms will be ready for installation as soon as the G10 cover plates are re-installed. Work continues on the new RF transmitters. PPPL is in the process of cutting to size and terminating 6" coax components for the installation. Control wiring continues to be installed. Fabrication of 10 out of the 14 fast control boards is complete. These boards provide antenna phase measurements, arc detection, plasma position feedback to the Hybrid computer, and general fault detection. We continue to work on the power distribution system for the DNB. Work on the 480 substation is progressing. The power distribution panel has been ordered, some cables run, and fuses have been specified for the 480 lines. An oil storage container is being designed to hold the oil needed to isolate supplies that must float at high voltage. Work by the University of Texas group continues on flange design and diagnostic layout. They are also making progress on the new scanning probe that will be used primarily for fluctuation measurements on C-Mod. The location for the probe has been determined, gatevalve control logic is being specified, and vacuum hardware components are being selected. We are delighted to report that Bill Rowan of the University of Texas has relocated to the Boston area to work full time at MIT. Prof. Anders Bondeson of the Chalmers University of Technology in Sweden is visiting the PFC this week. He is setting up his resistive MHD code, MARS, to analyze Alcator C-Mod data, in collaboration with Dr. Jesus Ramos of the PFC Theory Group.
