Minutes of the Feb 12, 2010 Tevatron Dept Meeting http://indico.fnal.gov/conferenceDisplay.py?confId=3136 * News (Ron) - Engineers' Week is coming up - be sure to hug your favorite Fermilab engineer. Also be sure to take the new Integrated Quality Assurance training soon - it's online. * Weekly Operations Summary (Dean Still) - The Tevatron delivered over 52 pb^-1 to the experiments over the past week. There have been 10 HEP stores with initial luminosities between 153 and 282 ub^-1/s. Store 7590 ended when a 3.8 magnitude earthquake nearby (about 20 miles) shoved the protons into the E0 collimators. Store 7597 had a B17 separator spark at flattop that blew up the beams and caused lower luminosity; it ended with a quench at A34, site of a known cryo leak, likely caused by a ice build-up and thermal bridge. Store 7601 aborted when a CAMAC controls crate died, causing an orbit distortion and high losses at E1; the loss monitor pulled the abort in time to prevent a quench. We continue to fight high losses during the squeeze. During accesses this week, an air leak was found on a collimator bellows near E0; it was vac-sealed but will likely return as this collimator is used/moved every store. Another very small air leak was found on the bellows between two of the B17 separators - it will be repaired during a future access. Safety system tests were completed, too. * Happenings at HINS (Bruce Hanna) - Bruce gave an overview of HINS activites. They have accelerated 2.5 MeV protons through the RFQ. The RFQ has an internal water leak that will be repaired soon. They want to test spoke-resonator cavities and a high-power RF vector modulator, among other things (instruementation, etc.) Eventually they want to have 10 MeV beam. * Plan for Next Week (All) - Deliver luminosity. - In store separator scan (Alex) - TEL-2 abort gap cleaning, beam-beam compensation (Alex, Giulio - EOS) - T-980 crystal collimator (Dean - EOS) - Chromaticity tracker (Tan - 150 GeV proton-only)
