Cosmic Simulations

TODO: page will detail specific terminology needed for simulating cosmics events

Livetime

Livetime of a given Cosmic sample can be established with the following command:

mu2e -c Offline/Print/fcl/printCosmicLivetime.fcl /pnfs/mu2e/tape/phy-sim/sim/mu2e/CosmicDSStopsCORSIKA/MDC2020n_10h/art/cb/f0/sim.mu2e.CosmicDSStopsCORSIKA.MDC2020n_10h.103.art

which will print out a list of quantities associated with the provided data-set. These include N Primaries, Area, LowE (lowest energy), HighE (highest energy), FluxConstant and Livetime. For the standard configuration, a single job corresponds to 0.062266 seconds of livetime.

Standard 10hour Configuration

Our standard jobs take "10 hours" of livetime. We configure our 0.062 s jobs in the following way:

• 500 jobs at Stage 1, this corresponds to 500*0.0622 = 31 s
• Resampling factor of 1000 = 31*1000 s = 8.6 hours
