beam: stage1

The simulation correcponds to 800 MeV proton interactions with carbon coveyor style target. Two data streams are recorded:

• dsregion: particles (mostly neutrals) reaching concrete walls covering CRV
• mubeam: beam particles reaching DS vacuum volumes.

Each unconcatenated file corresponds to 5E5 POT:

• The total simulated POT: 13.4E9
  • It corresponds to 8 ubunches, assuming 1.6E9 POT/ubunch

The stopping planes were arranged in the configuration described in docdb-26541. Truncated files are empty and can be recovered from the archive. The samples were produced on Bebop using 2.6M core-hours.

beam: stage2 (DS)

Resampled sim.mu2e.beam-g4s1-mubeam-cat.111520.art with JobConfig/beam/DS-resampler.fcl.

• Generated events: 1000*500,000=500,000,000
• Initital number of events from stage-1: 37,132,359
• Resampling factor: 500,000,000/37,132,359 = 13.6
• The total simulated POT: 13.4E9*13.6 = 180E9 POT
• The total number of pulses: 180E9/1.6E9 = 112
