=====Meeting Minutes March 2, 2012===== ===Present=== Suwat, Mike, Rachel, Bec, Bill, Dan, Betty, Jack, Zibi ====Conferences (Betty)==== * EOS meeting in Syracuse, Italy September 2012. Only those with results get to go. * Astrophysics meeting at MSU, October? 2012 * Nuclear structure meeting at Argonne, August 2012 ====Visitors (Betty)==== * Yingxun will be here for 3 weeks, starting May 13 * Our summer student is arriving around May 9 * Sergio is coming sometime in April ====Group Business==== * Lab Move: floor is finished, then they will paint the walls (maybe?). Possibly moving next week. * Efficiency (Jack): Two methods. A. Calculate fraction of the solid angle for each pixel. B. phi vs theta, times sin(theta)--integrate. Should equal A. For Method B to work, need enough bins in phi, theta and enough bins for each pixel * Lee's Experiment: no update on the preamp box. Got remaining chip boards. * HiRA Cans: ordering more screws. Jack will make sure Jimmy has the correct drawings. ====Updates==== * Mike: E vs. Theta in lab and center of mass. No efficiency correction (yet). Theta/dOmega not smooth through theta * Rachel: E vs Theta for 05049. Multiplicity issues: the miniball multiplicity is from the TDC, did not work for first 3/4 of the experiment. So for now will use CsI multiplicity for cuts * Zibi: study of varying theta(cm) cuts. Does not see a big dependence on width of Theta(cm) cut. * Cuts on centrality: affects single-yields but not double ratio * BUU: DR(n/p) always flat, DR(t/3He) increases with increasing energy (in calcium). ===Spring Break next week: only Friday group meeting!===
