Alcator C-MOD Weekly Highlights November 19, 1996 The C-Mod lower PF coil package has been inspected, cleaned up, and is ready to be reinstalled. Work on the lower EF1 pocket heaters is nearly done. The lower coil package will be installed as soon as the heater work is complete. The TF arm inspection continues. Work has focused on the lower arms so that the inspection will not impact the machine reassembly schedule. All tooling required for making the modification to the OH coaxes is in house. This work will begin as soon as the procedures have been reviewed. Work continued on several other engineering systems during the last week. The replacement interphase transformer for our PEI power supply has been installed. This supply is used to produce the toroidal magnetic field needed for electron cyclotron discharge cleaning. The high voltage transformer for the new ECDC magnetron has also been installed and is undergoing tests. The new ECDC unit will provide a backup system for the present magnetron, and will also allow up to 6 kW of RF power to be used during ECDC. Power and water installation continues on the DNB. The dummy load for the #1 and #2 transmitter has been reassembled and is being prepared for testing. The control wiring for the #3 and #4 dummy load is complete as are all plumbing and pump controls. The IPA and driver tubes for transmitter #3 have been installed. Mechanical modifications to the diver cabinets are nearly complete. A large fraction of our scientific staff attended the APS meeting in Denver last week.
