2. CLHEP and AIDA
Geant4 requires the installation of
CLHEP, release 220.127.116.11.
The installation of CLHEP-18.104.22.168 is mandatory for consistency in the
definition of masses and widths of particles. Earlier versions of CLHEP may
link, but they will not give correct results.
Geant4 9.2 examples with histogramming cowork with analysis tools compliant
to AIDA 3.2.1 interfaces (for details, see
Users Guide for Application Developers).
AIDA headers can be downloaded from:
3. Items for migration of the user code
Listed here is some relevant information on developments included in this
release, some of which may require migrations (mainly for users of advanced
Geant4 features) in order to upgrade from release 9.1 to release 9.2.
Note that for all users a full re-installation of libraries (or a full
recompilation) and a recompilation of user applications is required.
An additional optional Boolean argument has been added to the signature
of ComputeSafety() in G4Navigator. Any class inheriting
from G4Navigator has to adapt to the new signature.
Masses and widths of particles have been updated to be compliant with
PDG-2008. To maintain consistency this requires the upgrade to a new
version of the underlying CLHEP library (CLHEP-22.214.171.124), which includes
up-to-date constants as used by Geant4.
Low Energy Electromagnetic physics
- Geant4-DNA processes:
new elastic scattering models are available for electrons, replacing the
old ones. The user may use in his/her physics list either the Screened
Rutherford model or the Champion model; the models are alternatives and
must not be used together.
To use the Screened Rutherford model in the physics list, one should
define the elastic process as follows:
and register it as follows:
More details can be found in the advanced example microdosimetry.
To use the Champion model in the physics list, define the process as follows:
typedef G4DNAProcess ElasticChampion;
and register it as follows:
Documentation is also available from the
Energy EM working group page.
- New alternative implementation of Penelope processes compatible with the
standard EM design are included as Beta release. Information on how
to use these processes (Compton, Rayleigh, Gamma conversion, photo-electric,
annihilation and ionisation) is available through these
- The method MeanFreePath() in G4HadronicProcess will
become protected in the next release.
A new public method will be provided.
The obsolete method SetDispatch(), which is no longer used,
has been removed.
This release introduces new versions of two data sets.
Please see the corresponding details in
Section 10 of this document.
- New data for neutron cross-sections, G4NDL.3.13.
- New low-energy data set, G4EMLOW.6.2.
4. New Developments and Capabilities
Geometry & Field
Detector description persistency
- New locator classes and options are available for identifying the
intersection point of a charged particle in a field. These are Simple, Brent,
and Multi-level and allow the user to investigate tradeoffs between increased
accuracy and CPU speed according to the use case.
Multi-level is used by default to provide for robustness; the Brent method
is introduced as an alternative.
Interfaces & Visualization
- A new module for importing detector descriptions in ASCII text format
is now part of Geant4. Such a description can be used as an alternative
to GDML or other persistency techniques, and is provided with a corresponding set
of UI commands.
- GDML: the GDML plugin module adds export capabilities,
and thus replaces completely the external GDML module required in older versions
of Geant4. The GDML schema has been upgraded to support missing
solids and parameterisations.
The new GDML-3_0_0 schema is now recommended.
Low Energy Electromagnetic physics
- The layout of the Qt interface, G4UIQt, which was introduced in
release 9.1 as a Beta release, has been improved. It now supports both common
versions of Qt: Qt3 and Qt4, and provides all the functionality of previous
graphical user interfaces (such as Xm, Win32...). Also implemented a help
widget to easily browse the entire Geant4 command system.
- Major Improvements have been made to the Qt visualization driver. This
driver now includes all of the capabilties of the other OpenGL drivers,
but adds additional controls to rotate, translate, zoom, to export to many
graphics formats (jpeg, eps, ps, pdf) and to easily create visualization
- The 2D drawing capability has been extended; added in previous release just
for G4Text, it now also include G4Circle,
G4Polyhedron, G4Polyline, G4Polymarker and G4Square.
It allows placement in the 2D "screen window". Useful for tasks such as
creating legends or logos that stay put on the screen while you otherwise
rotate, translate or zoom the visualization.
Standard Electromagnetic physics

- Cubic Spline interpolation of dedx and cross section tables is
enabled by default. Better interpolation was found to increase stability
when varying transport parameters, such as cuts, of energy deposition of
hadrons. The old variant of linear interpolation is available as an option.
- A new process, G4eMultipleScattering, specialized for simulation
of e+ and e- multiple scattering has been added.
This process in turn uses a new model, G4UrbanMscModel2, which is
based on the G4UrbanMscModel of previous releases but has an
improved sampling algorithm and has been retuned to experimental data.
Several reference physics lists such as G4EmStandardPhysics now
use this new G4eMultipleScattering process.

advanced description of LPM effect; it can be applied for electrons and
positrons with E > 1 GeV and provides gamma spectra which agree
well with thin-target experimental data.
The density suppression effect in the old G4eBremsstrahlungModel
has been reviewed and improved.
- The G4IonFluctuations model has been updated: at high energy
it uses G4UniversalFluctuation, which provides Landau tail of
At low energies it uses Gaussian distribution based on experimental data.

Cerenkov threshold and a new user defined step limitation provides for
smoother X-ray emission.

fHadronAtRest = 151,
fChargeExchange = 161

7 GeV have been brought up to PDG values.
- Binary cascade: the cascade part remains unchanged, however, changes in
the pre-compound and de-excitation code will affect results for low-energy

added; it can be used for simulation, where required spatial precision is
much less than 1 mm.
- A new utility, G4PhysicsListFactory, is introduced; it allows
any reference physics list to be built.

5. Expected effects on physics and performance
Low-energy Electromagnetic physics
- Implementation improvements in G4Cons and G4Tubs
bring speed improvements on the order of 20% for those shapes
with pure-tracking (i.e. without field propagation or physics).
Standard Electromagnetic physics
- An updated version of the G4LogLogInterpolation class is included
in this release. This update improves the speed of low
energy EM Physics processes that use this class. Only insignificant
changes result in the interpolated values obtained and in physics
- More precise multiple scattering model for electrons and positrons
provides wider shower (about 0.5% measured for the CMS calorimeter).
- New relativistic Bremsstrahlung model is applied for electrons and
positrons; it provides gamma spectra which agree with thin-target CERN and
- The usage of the Spline approximation of dedx and cross section
tables provides a Bragg peak position which is stable within 0.1 mm
versus variation of production cut or step limit.
- Visible energy in sampling calorimeters may increase on the order of 1%
due to upgraded model of multiple-scattering and usage of Spline
- Changes to the Bertini cascade code have resulted in several changes to
energy spectra and shower shapes:
- the bug fix to multiplicity sampling resulted in cutting the
quasi-elastic peak height in half, more in line with the binary
- the same fix increased the multiplicity and decreased the mean energy
of pion secondaries, thus shortening the length of showers in
calorimeter tests by roughly 2% (depending on the physics list);
- CMS test beam studies show a significant reduction in non-linearities
in energy response to MIP like particles between 5 and
- improvements to the Coulomb barrier have significantly reduced the
number of protons below 20 MeV.
- Improvements in the precompound model have resulted in more realistic
neutron spectra at low energies. For 22 MeV protons on aluminum,
for example, the neutron spectrum now falls exponentially, as expected from
data. Before the changes, this spectrum was more or less flat.
This results in proportionally more neutrons at lower energies.
- Performance measurements carried out on realistic setups when using
QGSP_BERT for 50 GeV pi-, show an improvement of about
25% in CPU time. A slight degradation in performance of 1 to 3% is instead
measured for QGSP_EMV.
6. Known Run-Time Problems and Limitations
The following known issues affect the cylindrical scoring mesh feature and
are expected to be fixed in the next release.
For a complete list of outstanding run-time problems and to submit any
problem you may find while running this version of Geant4, please refer
- Rather frequent warning messages may be issued during tracking by the
G4Navigator, concerning zero-length steps. This does not affect
the correctness of the results and has been identified in the cases
where a track enters at exactly the center of the top/bottom circular
face along the local z-axis of the scoring cylinder.
- Speed of transportation in cylindrical mesh is known to be non-optimal
and will be improved in the next release.
- A problem for some scorers which use the volume size for cylindrical
mesh is identified due to faulty calculation of the geometrical volume
in such configurations. The following scorers currently should not be
used for cylindrical meshes (unless you hand-correct for the volume
after results are obtained): G4PSCellFlux, G4PSDoseDeposit,
7. Compilation Warnings
There may be few compilation warnings on some platforms.
We do not believe that any of these lead to incorrect run-time behaviour.
8. Known Run-Time Warnings
The following message can be written to standard output at the end of a program:
G4Transportation: Statistics for looping particles
Sum of energy of loopers killed:
Max energy of loopers killed:
It provides the total energy (in MeV) of tracks killed due to
excessive number of steps ('looping') during the simulation, and the maximum
energy of such a track. Such behaviour can be due to looping in magnetic fields
or encountering problems at geometrical boundaries.
In case either of these reported energies is significant, we recommend
increasing the verbosity of G4Transportation to obtain information for
each track killed. A user can change the threshold energy above which particles
are not killed using the method SetThresholdImportantEnergy of
G4Transportation. The default value is 250 MeV.
