2.8

Libraries Version

  • geant4: 4.10.06.p02
  • clhep: 2.4.3.1

Additional Options or features

  • added DIGITIZATION_TIMESTAMP option to pass to digitization routines

  • added DIGITIZATION_VARIATION option to be used by digitization routines.

  • added SHIFT_LUND_VERTEX option to shift a file generator vertex.
    example: -SHIFT_LUND_VERTEX="(0, 0, -3)cm"

  • added entry "doubleRotation" for volume rotation: this must be followed
    by a set of 6 numbers with units, describing two consecutive euler rotations.

  • GUI background color changed to white

  • Double radius for hits above thresholds

  • added JSON ouput for all generator options

  • Thanks to Richard Holmes: added FILTER_HADRONS options: when set to 1, do not write events if there are no hadrons.
    Otherwise if nonzero write only events having a hadron with matching ID. For example -FILTER_HADRONS=2212 for protons.
    Also, do not print progress if evtN hasn't changed.

  • added mirror hit process routine as standalone routine and bank

  • added FILTER_HITS options: when set to 1, do not write events if there are not hits.

  • Thanks to Richard Holmes: The RERUN_SELECTED option allows one to rerun multiple events whose RNG state was saved in a previous pass.

    For example, suppose there is a rare background signature of an electron between 100 MeV and 1 GeV in detector ID 1000
    and you want to visualize a few dozen such events to investigate where the background is coming from. You can do a batch
    run using

    -SAVE_SELECTED=“1000,11,100MeV,1GeV,trackE,./savedirectory”

    to save the RNG states for such events into the directory ./savedirectory. They are saved in files with names like run2event1322.rndm where 2 is the run number and 1322 is the event number.
    Then you can do an interactive run with the same gcard and option

    -RERUN_SELECTED=“2,./savedirectory”.

    Here 2 is the run number from the batch run. With this option, instead of generating new primaries as usual or reading
    them from the start of a generator input file, the same primaries as were used in the saved events are generated or read
    and they undergo the same processes as before, so these events can be visualized.

    Similarly one could rerun these saved events in a batch run with both

    -RERUN_SELECTED=“2,./savedirectory” -SAVE_ALL_ANCESTORS=1

    to get an output file with the ancestors bank showing information on all trajectories leading to hits in those events.
    This avoids having to use SAVE_ALL_ANCESTORS=1 on the full run when ancestors for only a few events are of interest.

  • Thanks to Richard Holmes: SAVE_ALL_ANCESTORS option to save ancestral trajectory to output.

    Implement ancestral trajectory saving to output. This is enabled with the option SAVE_ALL_ANCESTORS=1.
    Then information about any trajectories which are ancestral to hits in the detectors is written to a new bank named ancestors with bank tag 80.

    This can be useful particularly in combination with the RNG saving, especially once we work up a convenient way to rerun multiple events
    with saved RNG: run with SAVE_SELECTED= and the default SAVE_ALL_ANCESTORS=0 to get the RNG for the few events of interest, then
    rerun them with SAVE_ALL_ANCESTORS=1, then do post-analysis of their trajectory history.

  • Thanks to Richard Holmes: SAVE_SELECTED option to save selected event RNG states:

    Provides and implements a new command line option::

    -SAVE_SELECTED=“, , , , , ”

    This tells GEMC to save the RNG state in a file in directory for events in which there is a hit satisfying:
    Detector ID matches in all digit positions where does not contain ‘x’ AND

    Particle ID is AND is in the range from to is optional and defaults to the current directory

    For example::

    SAVE_SELECTED="7xx10000, 11, 0.0MeV, 2000MeV, trackE, ./"

    saves RNG state in files in the current directory for events in which there was a hit in detectors 70010000, 70110000, 70210000, etc. by an electron with energy from 0 to 2 GeV.

Various fixes

  • Thanks to Zhiwen Zhao: fix cylindrical-x and cylindrical-y field map bug
  • Thanks to Zhiwen Zhao: fix bugs in linear interpolation in cartesian_3d

Physics

  • added hBertiniCaptureAtRest, to process catalogueq
  • added "PhotoNuclear" entry in the physics option list as a check that this part is not included with the normal phys list constructors.

2.7

Libraries Version

  • geant4: 4.10.03.p02
  • qt: 5.10.1
  • clhep: 2.4.0.4

Additional Options

  • added FILTER_NULL_VARIABLES option. If set to one, do not write empty variables in the output.

  • added option RFSTART: Radio-frequency time model. Available options are:

    • "eventVertex, 0, 0, 0" (default): the RF time is the event start time + the light time-distance of the first particle from the point (0,0,0)
    • "eventTime".....................: the RF time is identical to the event start time

  • added DISPLACE_FIELDMAP and ROTATE_FIELDMAP options to displace and rotate a field map

Various

  • fixed case where GEMC_DATA_DIR environment does not exist
  • reintroduced material name in the gui
  • fixed 10 and 20 cases for FASTMCMODE in physics list
  • addition of 3D field map in cartesian coordinates

Physics

  • added PRODUCTIONCUTFORVOLUMES option. It is a list of volumes that will be assigned a production cut (in mm, last element of the list). Example:

    • PRODUCTIONCUTFORVOLUMES="outerMount, taggerInnerShield, outerFlange, outerMount, nut1, main-cone, DSShieldFrontLead, 100" will set the production cut for those volumes to 10 cm.

  • detectors and cad factory can read the env variable "GEMC_DATA_DIR" as a base path in the gcard
