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:

• 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

Detector Geometry

The detector geometry and material configuration used in MDC2020 is documented in X (add reference). A brief description of the major features is included below.

Detector Response Simulation

The detector response simulations used for MDC2020 include detailed models of the micro-physics (below the level of the Geant4 energy deposition), and the translation of those processes into digital signals. Details are described in the notes referenced in the table below. Note that a detailed model of the timing distribution system is also part of the digitization model.

Simulation Workflow

Datasets

MDC2020c are Validation datasets, ~1% samples used to test outputs and subsequent stages.
