Minutes of SuperB EMC meeting May 9, 2012 Indico agenda page is at: http://agenda.infn.it/conferenceDisplay.py?confId=5017 1) Presentation from Stefano on clustering and barrel electronics Slides at: http://agenda.infn.it/getFile.py/access?contribId=1&resId=0&materialId=slides&confId=5017 The neural net inputs used in the improved clustering are the time-sampled pulse heights. The zero time for this study is the MC-known bunch crossing. Slides are for x5 background. The .24 MeV for 140us shaping is from a combination of factors in the scaling (eg, PIN diode noise lower, gain lower, CsI(Tl) light yield higher). Ric is planning a measurement with PIN diodes for Elba. 2) Presentation from Valerio (reporting on work by Luigi Recchia) on electronics noise measurements Slides at: http://agenda.infn.it/getFile.py/access?contribId=0&resId=0&materialId=slides&confId=5017 The Hamamatsu CSP is used because it has variable integration time. Comment that optimal shaping may be different at 340V and 380V. 3) Discussion of TDR, especially forward section Slides from Ric at: http://agenda.infn.it/getFile.py/access?contribId=2&resId=0&materialId=1&confId=5017 Rome engineer has made contact with Jim Kay(?) at RAL (formerly Liverpool) concerning BaBar forward endcap. We are presently interested in the 3D CAD drawings of the C fiber structure. Various people talking with engineers at SLAC; agreed to have Kevin Flood as main liaison so they don't get overlapping requests. Many new drawings from BaBar; will try to use Rome repository begun by Corrado to collect and centralize. 4) AOB next meeting Wed, May 23 1730/0830
