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.
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)
Datasets
Datasets are presented in the order they were created. The primary dataset that users might be interested in using are in bold. The rest are related to making the main dataset, and are here for the record.
CRV flash
The first step is two jobs. The output of cd3 stage 1 was:
- sim particles from PS to the outside of the CRV (dsregion)
- sim particles from PS to TS2 (mubeam)
The "PS-CRV" job takes the dsregion sample and propagates it through the CRV. V7_0_0 release.

DS
The DS job takes the output of cd stage2 (particles traced down the beamline to TS5), and simulates them through the rest of the detector. The CRV hits are written out. The stopped muon in the target and everywhere else are written out to "TGTstops" and "OOTstops". The remainder is written the "beam". Release was v7_0_0.
