Oct 14, 2013 Status Reports Monica is having problems getting the cluster time and there are a few oddities. She will contact Jodi to see if she can put LUXSIM on the SMU cluster and run there. Chao is pretty much finished with the muon distribution work. Only thing left is incorporating the newest normalization info from Vitaly and finding a quantitative way to characterize the difference in elevations in the Lake (or North vs South) in the Soudan satellite vs slant path maps. Sean is working…

Synchronize your Sims * Install same GEANT4 version and identify a common physics list. The version we will use is 9.4.4 with the “shielding” physics list and the new MuNuc process. In order to make sure that this is indeed the same, Anthony will send around a first pass version after discussing it with Dennis and Mike at SLAC. This email exchange will iterate until a common set is decided upon.
