University of Wisconsin Reversed Field Pinch Boundary Study. Quarterly Progress Report, March 13-June 13, 1986

摘要

This report summarizes our progress during the fifth quarter of support of our RFP boundary study. We obtained bids on the first and major portion of the finish-machining of the vacuum containment vessel, and signed contracts with Sulzer the representatives of de Pretto-Escher Wyss (the VCV fabricator) to proceed. The Physics group agreed on the engineering features of the final machining which await only final drawings. Our Engineering Manage visited de Pretto-Escher Wyss in Italy and inspected the fabrication to this point, having also examined the work schedule, which remains compatible with the original goals. We continued to obtain improvement in the RFP plasmas created in the Octupole tank which reached reliable operation at the 300 kA level. Data sets on fluctuation measurements were obtained for wide ranges of q, from tokamak to RFP regimes. Our new data acquisition hardware and software were installed and tested. Major orders for vacuum equipment were completed. Major agreements on remodeling plans, and crane modifications were accomplished. The 1:8-scale wooden model was brought up to date. Programmatic tests of toroidal rail-limiters were initiated. Arc segments were fabricated for final welding of the optimized hoops, which we now plan to install early in August 1986.
