TrueBq01

TrueBq01 is a Geant4 simulation for cryogenic decay-energy spectrometery. It has been compiled using Geant4.10.6 on Windows using Microsoft Visual Studio Community 2019

TrueBq01 is based on the the rdecay02 example included with Geant4 distribtuions.

Installation Process

  1. Install Geant4
  2. Download source code folder (TrueBq01)
  3. Follow Geant4 user code compilation instructions
    3.1 I used Cmake version 3.19.2
    3.2 If using Visual studio, use configuration "Release" or "RelWithDebInfo" (not "Debug", which is default)

Running TrueBq01

From build directory (eg. TrueBq01-build)-
For batch file: TrueBq01-build> \Release\TrueBq01.exe batch.mac
For interactive mode: (w/ graphics): TrueBq01-build> \Release\TrueBq01.exe

Simulation information

Geometry:

  1. Rectangular solid absorber (gold as default material) sitting on a
  2. Rectangualr solid chip (silicon as default)

Dimensions of both solids can be set by user (e.g. in batch.mac)

Source:

Source is selected by the user; can be radionuclide or particle of a given energy.
Source distribution within absorber can be set in the macro.

Physics:

BiasedRDPhysics with Radioactivation Physics list selectable in source code

  • typically G4EmStandardPhysics_option4
  • for single scattering, use: G4EmStandardPhysicsSS

Event processing:

Decay Energy Spectrum of total energy deposited in the absorber is tallied in a histogram. Other histograms can be activate.
Options in macro to add Gaussian noise and tailing

Output:

Decay Energy Spectrum of total energy deposited in the absorber is saved inn custom .out file.
