Goals • Find energy and angle resolutions for low-energy electrons and photons generated with the particle gun and existing reco tools (last done by Z. Li) • Incorporate MARLEY into LArSoft (text files, and more elaborate software interface) • Run existing SNB simulation (Gleb, AJ, GENIE) and find energy resolution from - summed ADC charge - hit charge - space points with charge from PMA reco • Evaluate the angular resolution from reconstructed tracks • Make response matrices to incorporate into SNOwGLoBES • Study elastic ve+e -> ve+e scattering 3 8/2/16 Tom Junk | Supernova Hack Days
Goals • Port NOvA's GENIE-based SN vector generation module to LArSoft's GENIE instance. One bit of value-add here is to get a time-ordered sequence of neutrino events sampled from the "light-curve". GENIE doesn't know about time-varying fluxes. • Make a library of photon-detector waveforms with SNB events with and without 39 Ar events, to help the DAQ group study triggering, Zero-Suppression, and compression algorithms • Run MARLEY in LArSoft and look for nucleon emission. Look at reconstructed energy resolution for events with and without nucleon emission • Identify low-energy photons and include them in the energy reco • Evaluate the impact of spatial dependence of impurity concentrations affecting the lifetime and thus energy resolution 4 8/2/16 Tom Junk | Supernova Hack Days
Process • Preparation is important in order to maximize use of time – task proposals and homework worked great. • Tingjun and Tom helped solve technical issues and provide advice. • A spectrum of how aware participants were of the existing reco tools. More familiarity with simulation tools. • Participants were able to run standard MCC 6.0 workflows on SNB events and make event displays. Some issue with pedestals and zero suppression identified that affect the event display. • We tried out Gallery! And a request to try out igprof. Needed installation (both are available on scisoft.fnal.gov, but we should maintain installs on /grid/fermiapp) 5 8/2/16 Tom Junk | Supernova Hack Days

Reco algs may need optimization for SNB CLS Reco using PMA – Chiara Lastoria events. Different strategies for energy and angle may be optimal. ADC sum vs. tracking for example. 11 8/2/16 Tom Junk | Supernova Hack Days
