FHC pythia mini-bias simulation for Lambda

Updated on Wed, 2009-09-23 21:13. Originally created by xuanli on 2009-09-23 21:13.

    I use the pythia mini-bias codes to study to look for the lambda decay products energy deposit in FHC with Lambda->n+pi0.

SMD Problems at the sector boundary

Updated on Mon, 2009-09-21 13:42. Originally created by jwebb on 2009-09-21 12:36.
Abstract: Looks like there's yet another bug in the old EEMC geometry (which persists in my development version 5.21).  Throwing geantinos an phi = 105 degrees, we should be probing the boundary between two sectors (sectors 11 and 12 if I've got it right).  We expect to see two SMD planes.  We don't see two.  Worse, we don't see three (the only other valid possibility).  We see one plane.

Run 9 TPC field cage currents
