Datasets

Introduction

This page is an attempt to record the datasets created and uploaded by "production". These are semi-permanent datasets that were created for the collaboration as a whole. It is nearly impossible to maintain dataset information perfectly when any datasets can become invalidated in various ways, or completely obsolete, at any time, for many reasons. Please do not use any datasets without consulting experts in these datasets - that's still the best way to be sure you are using the right dataset.

To print lists of datasets that are known to SAM - all or optionally with restrictions (see -h).

051017

This sample of stage 1 beam simulation was generated in May 2017 to answer questions about CRV shielding. Default geometry. This sample is standard enough that it could be of use to other groups. Goals of this effort:

• Rates and dead-time with improved precision
• Sources of coincidences from neutrons and gammas
• Improved shielding and CRV geometry to mitigate rates and to increase CRV coverage (geometry changed in later stages)

The standard cd3 beam stage 1 fcl was modified to only write out the dsregion and mubeam datasets. Run in v6_2_1. See 8627 and 7040. Expert: Yuri Oksuzian.

• 500K jobs of 10K POT, total 5e9 POT
• cnf.mu2e.cd3-beam-g4s1.051017.fcl
• sim.mu2e.cd3-beam-g4s1cat-mubeam.051017.art (concatenated 20-to-1, uploaded)
• sim.mu2e.cd3-beam-g4s1cat-dsregion.051017.art (concatenated 20-to-1, uploaded)

geant4 v10 test samples

Run 11/2016 to 2/2017 to test geant4 v10. See doc-9336 doc-9624 doc-9402 doc-9139 doc-8357. For dataset details, see GeantV10Test. Expert: Ray Culbertson and Yuri Oksuzian.

MDC2018

A multi-phase production for future studies. The main goals are:

• Replace the MCStepPoint samples generated for the CD3 review with equivalent samples using updated geometry
• Provide calibration and analysis samples in 'digi' format
• Integrate CRV, Calorimeter and Tracker data
• Provide official samples of signal (mu->e- and mu->e+) and the principal 'faux signal' processes including DIO, cosmic spallation, RMC, RPC
• Provide 'Mock Data' samples of undifferentiated combinations of signal and faux signal processes, formatted as a high-level skim

MDC2018 samples are intended to facilitate algorithm development, not to support updated precision values of sensitivity or background rates. As such, some approximations are made in the generation compatible with results being accurate at the 90% level.

MDC2018 production started with the CD3 proton-on-target (stage1) output. As such, updates to the production target geometry were not included.

---

MDC2018 Geometry Many updates have been made to the geometry since CD3, including:

• 21.5mm diameter hole in the stopping target to reduce radiation load on the tracker and STM
• 18 evenly-spaced Tracker stations with brass shielding interleaved
• Updated calorimeter crystal sizes and positions
• More realistic description of supports, cabling, electronics, etc.
• Realistic magnetic field map inside the cryostat (Mau13)

Cosmics

Calibration Cosmic Test Sample

Calibration cosmics are events taken with a simulated trigger intended to collect all cosmics that hit a detector, for use in calibration studies. The digis for trk and cal are written out, as well as the StepPointMC's for CRV (the CRV product is being updated). Expert: Ray Culbertson

3/2018, three samples were generated, 1M events generated for each then some filtering.

• ext - detector extracted to +14m in z
  • Bfield is on but the default maps do not reach that far, so Bfield appears off
  • trigger on trk OR cal
  • Dataset: sim.mu2e.cosmic_calib_ext.180302.art
  • geometry: Mu2eG4/geom/geom_common_garage.txt (mods to Mu2eG4/geom/geom_common_current.txt)
  • Total cosmic rate = 1989.85 Hz for 1M events = 502s livetime
• ins - detect in normal inserted position
  • Bfield on
  • trigger on trk OR cal
  • Dataset: sim.mu2e.cosmic_calib_ins.180302.art
  • geometry: Mu2eG4/geom/geom_common.txt (->Mu2eG4/geom/geom_common_cd3_s4p2.txt)
  • Total cosmic rate = 1989.85 Hz for 1M events = 502s livetime
• crv - detect in normal inserted position
  • Bfield on
  • trigger on CRV hits
  • Dataset: sim.mu2e.cosmic_calib_crv.180302.art
  • geometry: Mu2eG4/geom/geom_common.txt (->Mu2eG4/geom/geom_common_cd3_s4p2.txt)
  • Total cosmic rate = 23010.7 Hz for 1M events = 43s livetime

target6/7 Study

Generated to study how cosmics enter the gap between the CRV top and sides, to help determine the CRV final design. Daya Bay generator. Summary talk 11147. Expert: Ralf Ehrlich.

• target6 - left (+x) top gap
• target7 - right (-x) top gap

Stages: same as cd3 processing.

6/2017 full listing

target5 Study

Generated to study cosmic rays that enter the TS hole and produce tracks, and how they can be degraded with new shielding blocks. This follows up on this category of events discovered in CD3 target1. Daya Bay generator. Talk summary 8322. Expert: Ray Culbertson.

The talk shows the various shielding configurations and concludes new shielding would help. Stages:

• s1 - v579, generate on a plane that is the TS opening, sim to a surface between TS3 and TS5
• s2 - various branches off of v579, complete sim, reco, require a track 50-200 MeV.

The job were run around 11/2016.
