Alcator C-MOD Weekly Highlights November 2, 1994 Maintenance and repair operations on Alcator C-MOD are nearing completion. Pump-down of the machine is scheduled for later today. All in-vessel activities have been completed. New cabling was installed on all ten divertor halo current shunts. The first wall and divertor thermocouple arrays were connected and checked out. Cover plates over all internal cable runs were installed. Divertor hardware torque was checked. Alignment and calibration of all H-alpha arrays was completed. Alignment of the bolometer arrays was completed. The vessel interior was cleaned out, and a thorough final inspection, including production of a video record, was carried out. All vertical port closures and gate valves have now been installed and torqued up. Flanges on C- and G-horizontal ports, which are used for manned access to the vessel, are being readied for installation. The turbo-pump station has been operating since last week, and is ready for machine pump-down. The igloo top was temporarily installed in order to carry out a calibration of the neutron detector system. The calibration, employing an in-vessel source was carried out over a 12 hour period on Sunday. The igloo top was then removed to allow final connections to be made. All of the vessel heaters have been checked out and are ready for operation. New isolation amps from the magnetics rack to the Hybrid control computer have been installed. The instrumentation for the new OH coax bus diagnostics is complete and ready for installation.
