July 25 – July 27, 2016 Fish Tank

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

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 39Ar 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

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)

CLS Reco using PMA – Chiara Lastoria

Reco algs may need optimization for SNB

• events. Different strategies for energy and

angle may be optimal. ADC sum vs. tracking for example.
