Alcator C-MOD Weekly Highlights October 6, 1994 The maintenance/repair period is continuing this week. Excellent progress has again been made on the tokamak re-assembly. The OH1 and OH2U coax busses were installed and torqued to specification. Following final inspection of these coaxes, the upper wedge plate was installed. The upper radial TF magnet arms were then installed, and the spring plates, used to maintain compression of the feltmetal in the sliding joints, were installed at the top inner joints. The vertical TF arms were installed, and the spring plates inserted in all the outer joints. Inspections and testing, including hi-potting were then carried out. The TF magnet assembly is now complete. A fitup of the EF coaxes and OH coax extensions was performed in preparation for cylinder installation. Following final inspections, the outer cylinder was installed. All ten "teardrop" adaptors on the lower vertical flanges have been installed. Now that the cylinder is in place, installation of the horizontal port extensions has begun. The bus tunnel, which had been pulled back during the machine dis-assembly, has been moved back to its normal position. Dr. Edmondo Giovannozzi has started a three month visit at Alcator C-Mod from the Frascati FT tokamak group. He will be working with Reich Watterson on improvements to the calibration systems of the C-Mod Scanning YAG Thomson scattering Diagnostic.
