Alcator C-Mod Weekly Highlights November 27, 2006 FY2007 weeks of research operations: tentative target: 15 weeks Completed: 0 weeks Physics ------- The 2007 Alcator C-Mod Ideas Forum will be held from December 13 to 15, 2006. The purpose of the Forum is to solicit proposals for experiments on the C-Mod tokamak for the upcoming run campaign, which is scheduled to begin in February 2007. The Forum is open to all interested parties, including current collaborators and potential future collaborators. We actively solicit proposals from the entire fusion community. -- Important deadlines Proposal title submission: December 6, 2006 (close-of-business) Electronic submission of final presentations: December 12, 2006, 12 noon Please email submissions to: ideasforum@psfc.mit.edu -- Detailed information about the Forum can be found at: http://www.psfc.mit.edu/cmod/sciprogram/ideas2007/ -- Location All sessions will be held in the main conference room of the MIT Plasma Science & Fusion Center: Room NW17-218 175 Albany Street Cambridge, MA Remote presentation capabilities will be available. The following research program information will be useful for those interested in creating a proposal: http://www.psfc.mit.edu/research/alcator/program/index.html On this web page you can find links to --current and past C-Mod work proposals --C-Mod 5-year plan --PPPL/C-Mod Collaboration plan --previous two Ideas Fora --existing C-Mod mini-proposals If you have questions or comments, please contact Jerry Hughes (jwhughes@psfc.mit.edu) who is coordinating this year's Forum. Operations ---------- During the three day holiday week we continued work on new diagnostic systems and diagnostic upgrades needed for the upcoming run campaign including micro-balances for the Surface Science Station, bolometry, Thomson Scattering, Langmuir probes, CXRS, and interferometry and polarimetry. Welding of the F-Hor flange has begun. Work also continued last week on installation of tiles on the cryopump upper divertor protection plates and assembly of the tungsten tile modules for the outer divertor. Lower Hybrid System ------------------- Design of the filament supply and instrumentation and the RF drive system for the klystron test stand is nearly complete. PLC hardware for the test stand is being configured, and PLC software developed. A lower hybrid meeting was held last Wednesday during which a decision was made to fabricate the new stainless steel couplers using the double flange design. This design change will also require changing the nominal radial position of the launcher and extending the length of waveguide between the vacuum window and the plasma approximately 3 cm. Diagnostics ----------- Control computers have been ordered for the piezoelectric feedback systems for the Two Color Interferometer (TCI) and the Polarimeter. The TCI system will null out vibrational phaseshifts into the kHz range, while the Polarimeter system will maintain beam alignment in real-time (several hundred Hertz freq response). ICRF Systems ------------ Work began in the high-yard last week with routine maintenance of the Ross bottles which are part of the step-start system for the transmitter high voltage power supplies. We continued refurbishment work on the ICRF antennas and vacuum feedthroughs. Work on the FFT control system also continued. _______________________________________________ Cmod_weekly mailing list Cmod_weekly@lists.psfc.mit.edu http://lists.psfc.mit.edu/mailman/listinfo/cmod_weekly
