MDC2020

Introduction

MDC2020 is an end-to-end production using updated geometry, detector simulations, persistent schema, and simulation workflows compared to MDC2018. The goal is to provide a reasonably complete and accurate model of what Mu2e will record during commissioning and first running period ('Run 1', add reference), including OnSpill, OffSpill, and Extracted Position samples. The primary intended use case of these samples are:

General Notes and Updates
Detector calibration and alignment, including cross-system (ie CRV to Calo) calibrations
Detector commissioning
Trigger algorithm testing and development
TDAQ to Offline data transfer workflows
Offline reconstruction algorithm development
Science extraction framework and algorithm development

The detailed technical documentation of MDC2020 is in Doc-DB 44084. These pages provide a list of the datasets produced and give time-dependent information.

General Notes and Updates

As reported in this presentation the G4 code used in all the MDC2020 simulations had missing contributions from delta rays in the calorimeter. This appears to mostly affect signals from cosmic muons. For precision studies using cosmic muons please contact the experts.

Simulation Workflow

The samples described on this page were produced using the following workflows. Jobs were submitted using POMS.

Cosmic Simulation campaigns

The cosmic simulation creates a sample of cosmic rays with three different configurations:

Standard position, magnetic field on
Standard position, magnetic field off
Extracted position, magnetic field off

Beam Simulation POMS campaign

The goal of the beam campaign is to generate the particles needed for mixing (muons, electrons, neutrals) starting from the protons on target (POT stage).

Digitization and mixing POMS campaign

For each primary (e.g. DIO, CeEndpoint, CePlusEndpoint, etc.) we run digitization and reconstruction with ("mix" output) and without beam mixing ("digi" output). The beam mixing stream is divided into three branches one per configuration ("perfect", "best", "reco").

To run mixing on a new primary you should use a clone of the production POMS campaign, substituting your primary for one of the existing (CeEndpont, etc). Note that the new primary must have been entered into the SAM database as part of MDC2020 production, preferably using a clone of the primary POMS campaign.

to TEST mixing, you can manually invoke the scripts, as in the following example:

> cd mymusedir
> muse setup
> setup dhtools
> setup mu2etools
> kx509
> vomsCert
> git clone git@github.com:Mu2e/Production.git
> source Production/Scripts/gen_Mix.sh CeEndpoint MDC2020 p r v perfect v2_0 1BB
> mu2e -c CeEndpointMix1BB_000/cnf.mu2e.CeEndpointMix1BB.MDC2020v_perfect_v2_0.001210_00000000.fcl --nevts 10

Recent Campaigns

The most recent MDC2020 campaigns are detailed below along with their Offline and Production versions as well as any useful information:

Campaign	Offline ver	Production ver	Comments
`MDC2020r`	`v00_09_02`	`v10_15_01`	`bug fix for digi stage`
`MDC2020t`	`v10_17_00`	`v00_09_11`	`several updates to many directories`
`MDC2020v`	`v10_20_00`	`v00_12_00`	`Special run (see below), not for standard physics studies!`

Current Datasets

These are the datasets currently available which correspond to the full 100% campaign. The three digi and reco configurations ("perfect", "best", "reco") correspond to three different detector conditions as described in DocDB 42036.

The digitization stream is divided into five parts: Signal, Diag, Trk, Calo, Untriggered, which are described in DocDB 41757. To obtain details (number of events, number of files, GB, etc.) about a dataset you can use the datasetSummary.sh script, available in the Production repository.

In the following summary, [stream] can be Untriggered, Calo, Signal, Diag, Trk and [purpose] can be perfect, best, startup. The digitization [digi] can be Mix[intensity] for mixed samples, OnSpill for unmixed samples. An [intensity] of 1BB corresponds to 1 booster proton batch, 2BB means 2 booster proton batches. MDC2020 also supports 'Low' intensity, but no production samples of that have been produced yet. 'Sequential' mixing is a special case where a fixed pattern of individual proton bunch intensities from a detailed beam slow extraction simulation is used instead of the lognormal intensity generator. Reconstructed (mcs) datasets are currently only available for Signal the stream.

NB: due to a configuration bug the CosmicLivetime data product was dropped from the dig and mcs datasets for MDC2020v production and earlier.

Special datasets

In order to assess the impact of a degraded field from coil 11 in the DS a special CeEndpoint campaign was run. In total 100K CeEndpoints were ran with the updated field map which was passed to the Mu2e/Offline code via the Production scripts. This is currently tagged as MDC2020v. Mixed and OnSpill samples were produced assuming 1BB mode of operation. The datasets with degraded DS field are:

Flat Gamma Samples

The following samples were made with these changes to the ``PrimaryFilter":

MinimumPartMom : 20.0 # MeV/c (nominal = 50)
MinimumTrkSteps : 2 # primary must produce at least this many TrkSteps (nominal = 12)
MinimumSumCaloStepE : 5.0 # or at least this much calo energy (nominal = 5)

A Flat photon 70-102 MeV/c spectrum was generated from initial stopped muons, detector steps and digi files are available:

dig.mu2e.FlatGammaOnSpillConv.MDC2020z_sm3_perfect_v1_0.art

Detector Background datasets

The final production background datasets for normal mixing are listed below. Note that normal workflows do not require you to ever directly access these: mixing jobs to use these should be configured using the Production/Scripts/gen_Mix.sh script.

The NeutralsFlashCat and EleBeamFlash datasets are quite large and require a lot of staging time and space

In addition, there are production background datasets for early digitization mixing listed below. Note there are no 'Early' MuStopPileup, as the standard dataset version of those works fine for early (>200ns) digitization mixing.

Stops

Dataset	Description
sim.mu2e.MuminusStopsCat.MDC2020p.art	Negative muon stops in the stopping target, used in muon daughter primary and pileup production campaigns
sim.mu2e.IPAMuminusStopsCat.MDC2020r.art	Negative muon stops in the IPA, used to produce calibration samples of Michel electrons
sim.mu2e.MuplusStopsCat.MDC2020t.art	Positive muon stops in the stopping target. There are only a few thousand of these and they are highly asymmetric

Pions

The pion beam campaign is a separate one from the main muon campaign. The naming convention for the various stages follows that of the muon beam campaign. Two pion beam campaigns were carried out: MDC2020r and MDC2020t

Dataset	Description
sim.mu2e.PuminusStopsCat.MDC2020t.art	Negative pion stops in the stopping target, pions have an infinite lifetime
sim.mu2e.PuplusStopsCat.MDC2020t.art	positive pion stops in the stopping target, pions have an infinite lifetime

Older Datasets

1% and 10% test datasets were produced when testing MDC2020, these still show up in samweb listings but have been superseded and should not be used anymore. This includes datasets with the following descriptions: MDC2020k MDC2020km MDC2020n_10h MDC2020n_10pc
