NEXTSim Changelog

Cory R. Thornsberry

Last updated: October 6, 2019

This changelog is used to keep track of major changes to the NEXTSim master branch which will directly affect end users. It should be updated any time a branch is merged into the master branch.

The most recent release will appear at the top with each release having a header indicating its commit number (or version number in the future) and date.

ab15bfc->dba6e03

Added

  • Added nDetDetectorTypes namespace which contains all detector geometry builders
  • Added changelog.sh shell script which may be used to easily generate new entries for this changelog

Changed

  • Detector geometry builders now inherit from nDetDetector class, making it easier for users to add their own custom detector geometry

da7f293->ab15bfc

New Commands

Command Name Description
setWorldSize Set the size of the experimental setup area
setWorldFill Set the material to use to fill the volume of the setup area (default=air)
setWorldFloor Add a floor to the setup area
setWorldPitSize Add a hollow pit to the floor of the setup area
addPrimitive Add a Geant primitive object to the setup area
listPrimitives List all the available Geant primitive objects
printObjects Print information about all user-defined primitive objects in the setup area
listMaterials List all currently loaded materials
searchForMaterial Search for a material in the NIST database
readMaterial Build a new dynamic material by reading a material file
printMaterial Print information about a currently loaded material
setAdcClock Set the period of the ADC clock (default=4 ns)
setAdcFrequency Set the frequency of the ADC clock (default=250 MSPS)

Added

  • Added new commands for setting properties of the experimental setup area (setWorldSize, setWorldFill, setWorldFloor, and setWorldPitSize) as well as the command addPrimitive to add 3d primitive objects to the world
  • Added new command readMaterial which may be used to dynamically define a new Geant material at run-time instead of needing to add the material to the source code and recompile
  • CMake now reports the ROOT and Geant version numbers at build time
  • When setting the single-photon response function using setFunction, the user may now specify either (0, 1, or 2) as before or the name of the function (expo, vandle, gauss)
  • Included random ADC latching time offset [-adcClock/2, adcClock/2] to light pulse digitizer (automatically subtracted after performing CFD)
  • Added --version argument flag which prints the current NEXTSim commit number which is being used
  • Added version (commit number) string to the output root file

Changed

  • Moved /nDet/detector/loadGDML command to /nDet/world/loadGDML
  • Modified default output filename so that it no longer contains colons
  • Changed output TTree title to something more accurate

Bug Fixes

  • Fixed discrete energy level bug in nDetParticleSource which prevented the user from changing the particle type of the level when adding it to the source
  • Fixed erroneous partice source level not being cleared correctly, causing particles with the incorrect energies to be emitted from the source
  • Fixed light pulse digitization error which was causing bias in the particle time-of-flight when using CFD on the detector light response pulse

Removed

  • Removed shadow-bar commands setShadowBarSize, setShadowBarPos, and setShadowBar as they are now made redundant under the new addPrimitive command

August 9, 2019

435a913->da7f293

New Commands

Command Name Description
setGaussianEnergy Set the energy distribution of the current particle source to gaussian
message Print a status message to stdout
setSegmentWidth Set segmented detector segment width/height
printAll Print parameters for all defined detectors
setTrapezoidAngle Set the trapezoid angle for elliptical detectors

Added

  • New gaussian type single-photon response function (setFunction 2)
  • Doxygen documentation for user action headers

Bug Fixes

  • Removed all ROOT classes from spectralResponse class in order to fix segmentation faults related to TGraph and TF1 objects

July 19, 2019

e7801b5->435a913

Added

  • Added true (4pi) isotropic sources
  • Added cylindrical detector type
  • Added circular PMTs, grease layers, and diffusers as well as conical light-guides
  • Added example macro to load external GDML models along with an accompanying example STL file

Removed

  • Removed obsolete ROOT macros

Bug Fixes

  • Fixed dynamic detector assembly volume size for user-added components such as diffusers and light-guides

July 3, 2019

ead45d5->e7801b5

Modifications

  • Updated example macros to work with modified macro commands
  • Moved material definitions from nDetConstruction class to new class nDetMaterials in order to decrease the complexity of the detector construction class

Bug Fixes

  • Fixed compiler warning about unused parameter in nDetTrackingAction
  • Fixed built-in 252Cf neutron source not emitting neutrons

July 1, 2019

Initial Release (ead45d5)
