GEMC Release 6.1

This version includes:

  • Expanded run-dependent geometry for BAND, RGK targets, magnets, HTCC, and micromegas.
  • Updated ATOF and CTOF digitization, including run-dependent timing and hit-position corrections.
  • Corrected ALERT helium materials.
  • Reworked DDVCS flux detectors and added the missing MuRT gcard.
  • Added deployment, binary-package, and GEMC2 reference-HIPO workflows.

Based on Coatjava Release 14.1.2.


Release notes

  • Fixed SQLite run fallback selection by sorting run candidates before choosing the latest run less than
    or equal to RUNNO.
  • Added run-dependent BAND presence transitions and SQLite/TEXT gcards using the default variation.
  • Added RGK fall 2023 and spring 2024 targets and populated their run-dependent geometry and CAD rows.
  • Updated ATOF timing digitization with fixed timing resolutions and run-dependent radiation-damage
    corrections read from the slope and intercept constants.
  • Corrected CTOF hit-position-bin loading and application, including use of the hit's laboratory z
    coordinate.
  • Corrected the ALERT helium target composition and increased the ATOF helium-gas density from 3 atm to
    4.5 atm.
  • Reworked the DDVCS central, shield, and forward flux detectors as thin scoring planes and corrected the
    DDVCS digitization variation.

Documentation

  • Documented the BMT and FMT z-position parameters and the shifts applied to match the CLAS12 configuration
    gcards.

Examples

  • Added the missing MuRT gcard.
  • Added dedicated BAND SQLite and TEXT gcards and renamed the BAND geometry, hit, and material variation
    files from main to default.
  • Updated the DDVCS gcard to use the shared fluxDets geometry and the rgd_fall2023_mc digitization
    variation.

Tests

  • Updated geometry comparisons to use run numbers appropriate to RGK, beamline, target, micromegas, and
    BAND configurations.
  • Added workflows that build and publish multi-architecture container images and binary tarballs, then test
    the tarballs in minimal supported environments.
  • Added a workflow that produces rolling GEMC2 reference HIPO files for GEMC3 histogram comparisons.
  • Changed the development-versus-main geometry comparison workflow to manual dispatch only.

Compatibility notes

  • BAND now uses the default variation instead of main. Custom BAND gcards that select main must be
    updated.
  • CLAS12 magnet CAD rows are stored under magnets_cad, matching the supplied SQLite gcards.
  • The rgk_winter2023 comparison uses RUNNO=19200.
  • rgd_fall2023_Cu and rgd_fall2023_Sn use the rgd_fall2023_CuSn target variation. Matching SQLite
    runs include 18347, 18372, 18560, 18660, 18874, and 19061.
  • CTOF CAD in the 5.14 rga_fall2018 geometry is missing the upstream light guides. Their presence in the
    SQLite geometry is a known 5.14 omission, not a 6.1 regression.

Detailed list of changes and fixes

  • Applied CLAS12 gcard BMT and FMT shifts directly through micromegas parameters and corrected the RGD
    micromegas positions and dimensions.
  • Corrected the RGK winter 2023 SQLite gcard so it uses its real run number instead of falling back to run
    11.
  • Populated target CAD SQLite rows for RGA, RGB, RGD, RGE, RGF, and RGK run-dependent variations.
  • Imported HTCC CAD definitions from gxml into SQLite while preserving their CLAS12-relative CAD paths.
  • Stored magnet CAD definitions using the detector name expected by the SQLite gcards.
  • Corrected the beamline CI run-to-variation mapping and added RGK runs to micromegas and target checks.
  • Added ATOF slope and intercept tables and applied their run-dependent timing correction.
  • Corrected ATOF and ALERT helium material definitions.
  • Corrected CTOF binned hit-position calibration loading and response calculation.
  • Added BAND SQLite rows for each detector-presence transition across the supported real-run-number ranges.
  • Replaced the two original DDVCS flux volumes with central and forward polycones and twelve sector/layer
    shield scoring planes.
  • Added automated deployment, binary-tarball validation, and rolling reference-HIPO generation.
  • Disabled the scheduled development-versus-main comparison while retaining manual execution.
