E895 Meeting Minutes 18 February, 1997 Attending: Gulshan Rai, Nathan Stone, Dieter Best, Heng Liu, Jim Draper Hans Georg Ritter, James Symons, Lee Schroeder ------------------------------------------------------------------------ News & Status Report: GR - We start with EOS news first. HGR - Marvin Justice will finish his strangeness paper this week, then we can circulate the paper. GR - APS conference is coming up at Washington, DC. - Another conference on the Intersections of Particle and Nuclear Physics is going to happen in May at Big Sky, Montana. Somebody should represent the E895. - Gatlinburg meeting in June, abstract deadline is March 1. - PDSF user's meeting is tomorrow in 50A-1116. Dieter is going to represent us. HGR - Our Grand Challenge proposal about the resource requirement has been accepted by NERSC. DB - gave his talk for tomorrow's PDSF user's meeting. He first introduced the E895 experiment, then he talked about the general data production scheme that we're running now and some resource requirement are being presented. Various suggestions are being made. JD - gave an update on the laser calibration. The drift velocity from TPC laser and canary agree with each other within 0.5% overall. So in the region where canary is malfunctioning, results from TPC lasers can fill in. - Juan Romero has done some beam energy study with MUSIC data. The beam energy is about 3.94 GeV, with error of 0.1 GeV. If the MUSIC position is off beam by 1 inch, it will give rise to the above uncertainty. This result is still tentative, it's subject to drift velocity check. (check out E895 home page). NS - Mark said TASGEN is ready and we will put it into CVS soon. GR - The time offset extracted from beam events is different from the one calculated by using the top edge method, which is about 2cm. It's hard to believe that the survey result is wrong. - Director's review committee will be here at the end of March, we should consider what to present. - I spoke with Phil Pile, situation looks tight for heavy ion run. - Mike Lisa is proposing a software meeting at Ohio State. After discussion, we feel this meeting is too soon. Prepared by Heng Liu
