<H2>3. Items for migration of the user code</H2>
|
|
|
|
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 <TT>ComputeSafety()</TT> in <TT>G4Navigator</TT>. Any class inheriting
|
|
from <TT>G4Navigator</TT> 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-2.0.4.2), which includes
|
|
up-to-date constants as used by Geant4.

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.<BR>
|
|
To use the Screened Rutherford model in the physics list, one should
|
|
define the elastic process as follows:
|
|
<PRE>
|
|
typedef G4DNAProcess<G4CrossSectionElasticScreenedRutherfordHE,
|
|
G4FinalStateElasticScreenedRutherford>
|

|
|
G4FinalStateElasticBrennerZaider>
|

ElasticScreenedRutherfordLE;
|

</PRE>
|
|
and register it as follows:
|
|
<PRE>
|
|
processManager->AddDiscreteProcess(new ElasticScreenedRutherfordLE("ElasticScreenedRutherfordLE"));
|
|
processManager->AddDiscreteProcess(new ElasticScreenedRutherfordHE("ElasticScreenedRutherfordHE"));
|
|
</PRE>
|
|
More details can be found in the advanced example <TT>microdosimetry</TT>.<BR>
|
|
To use the Champion model in the physics list, define the process as follows:
|
|
<PRE>
|
|
typedef G4DNAProcess<G4CrossSectionElasticChampion,
|
|
G4FinalStateElasticChampion> ElasticChampion;
|
|
</PRE>

<UL>
|
|
<LI>New <I>locator</I> 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.
|

<LI>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.</LI>
|
|
<LI>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.</LI>

<UL>
|
|
<LI>The layout of the Qt interface, <TT>G4UIQt</TT>, which was introduced in
|
|
release 9.1 as a <I>Beta</I> 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.</LI>
|
|
<LI>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
|
|
movies.</LI>
|
|
<LI>The 2D drawing capability has been extended; added in previous release just
|
|
for <TT>G4Text</TT>, it now also include <TT>G4Circle,
|
|
G4Polyhedron, G4Polyline, G4Polymarker</TT> and <TT>G4Square</TT>.
|
|
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.</LI>

tables. New templated classes are <TT>G4IonParametrisedLossModel</TT>
|
|
and <TT>G4IonParametrisedLossTable</TT>.</LI>

<LI>Two new total cross section classes for electron elastic scattering in
|
|
liquid water below and above <TT>200 eV</TT>:
|
|
<TT>G4CrossSectionElasticScreenedRutherfordLE</TT> and
|
|
<TT>G4CrossSectionElasticScreenedRutherfordHE</TT>;</LI>
|
|
<LI>New alternative elastic scattering model for electrons in liquid water

<LI>Cubic Spline interpolation of <tt>dedx</tt> 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.</LI>
|
|
<LI>A new process, <TT>G4eMultipleScattering</TT>, specialized for simulation
|
|
of <TT>e+ and e-</TT> multiple scattering has been added.
|
|
This process in turn uses a new model, <TT>G4UrbanMscModel2</TT>, which is
|
|
based on the <TT>G4UrbanMscModel</TT> of previous releases but has an
|
|
improved sampling algorithm and has been retuned to experimental data.
|
|
Several reference physics lists such as <TT>G4EmStandardPhysics</TT> now
|
|
use this new <TT>G4eMultipleScattering</TT> process.</LI>
|
|
<LI>A new class <TT>G4WentzelVIModel</TT> for multiple scattering of muons and
|
|
hadrons is available as a prototype for validation.</LI>
|
|
<LI>New bremsstrahlung model class, <TT>G4eBremsstrahlungRelModel</TT>, includes
|
|
advanced description of LPM effect; it can be applied for electrons and
|
|
positrons with <TT>E > 1 GeV</TT> and provides gamma spectra which agree
|
|
well with thin-target experimental data.<BR>
|
|
The density suppression effect in the old <TT>G4eBremsstrahlungModel</TT>
|
|
has been reviewed and improved.</LI>
|
|
<LI>The <TT>G4IonFluctuations</TT> model has been updated: at high energy
|
|
it uses <TT>G4UniversalFluctuation</TT>, which provides Landau tail of
|
|
fluctuations.
|
|
At low energies it uses Gaussian distribution based on experimental data.</LI>
|
|
<LI>The <TT>G4Cerenkov</TT> process now enforces a step limitation at the
|
|
Cerenkov threshold and a new user defined step limitation provides for
|
|
smoother X-ray emission.</LI>
|
|
<LI>A new <TT>G4EmSaturation</TT> class is introduced for sampling of Birks
|
|
saturation.</LI>
|
|
<LI>A new <TT>G4ElectronIonPair</TT> helper class based on the ICRU'31 report has
|
|
been added; it can be used for sampling electron/ion pairs in sensitive
|
|
detectors.</LI>
|
|
<LI>A new <TT>G4EmConfigurator</TT> class can be used for configuration of
|
|
models in physics lists.</LI>
|
|
<LI>Initialization of <TT>SubType</TT> has been added for all processes.</LI>

<LI>The printout describing processes, models and their parameters
|
|
initialised for a run have been upgraded.</LI>

|
|
<LI>Bertini cascade:
|
|
<UL>
|
|
<LI>Barrier penetration has been added to the Coulomb barrier.</LI>
|
|
<LI>A bug in the final state multiplicity sampling has been fixed, thereby
|
|
correcting the quasi-elastic peak which was too large.</LI>
|
|
<LI>Very low values of two-body internal pion cross sections above
|
|
<TT>7 GeV</TT> have been brought up to PDG values.</LI>
|
|
</UL></LI>
|
|
<LI>Binary cascade: the cascade part remains unchanged, however, changes in
|
|
the pre-compound and de-excitation code will affect results for low-energy
|
|
secondaries.</LI>
|
|
<LI>The INCL/ABLA cascade/evaporation model is now officially released.
|
|
It can be used for incident <TT>p, n, d, t, 3He, alpha</TT> and
|
|
<TT>pions</TT> from <TT>200 MeV</TT> up to <TT>3 GeV</TT>, on nuclei
|
|
ranging from carbon to uranium.</LI>

<LI>The quantum molecular dynamics (QMD) model for nucleus-nucleus collisions
|
|
is now in <I>Beta</I> release. It is valid from <TT>50 MeV</TT> to
|
|
<TT>5 GeV</TT>.</LI>
|
|
<LI>The class <TT>G4GlauberGribovCrossSection</TT> now provides a smooth
|
|
transition with the Barashenkov cross sections at <TT>90 GeV</TT>.</LI>
|
|
<LI><TT>G4ChargeExchangeProcess</TT> and <TT>G4ChargeExchange</TT> model are
|
|
now ready to be used in physics lists; the low energy threshold is set to
|
|
<TT>1.0 MeV</TT>. </LI>
|
|
<LI>Several improvements have been made to the pre-compound model.
|
|
Missing pieces of theory were added and several code fixes
|
|
were made to <TT>G4PreCompoundModel</TT> and related classes.</LI>
|
|
<LI>De-excitation and evaporation:
|
|
<UL>
|
|
<LI>Several corrections to the multi-fragmentation model to ensure it
|

<LI>New inverse cross sections and fixes of evaporation probabilities</LI>
|
|
<LI>FermiBreakUp is now switched off by default.</LI>

|
<LI>The pairing correction in excitation energy have been fixed in
|
|
<TT>G4GEMChannel</TT>.</LI>
|

</UL></LI>
|
|
<LI>Nuclear mass tables: in order to use nuclear masses consistently throughout the

The following known issues affect the cylindrical scoring mesh feature and

<UL>
|
|
<LI>Rather frequent warning messages may be issued during tracking by the

<TT>G4Navigator</TT>, 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.</LI>
|
|
<LI>Speed of transportation in cylindrical mesh is known to be non-optimal
|
|
and will be improved in the next release.</LI>
|
|
<LI>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): <TT>G4PSCellFlux, G4PSDoseDeposit,

G4PSPassageCellFlux, G4PSCylinderSurfaceCurrent,

Sum of energy of loopers killed:

|
|
It provides the total energy (in <TT>MeV</TT>) 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.

<P></P>

In case either of these reported energies is significant, we recommend

increasing the verbosity of <TT>G4Transportation</TT> to obtain information for

each track killed. A user can change the threshold energy above which particles
|

are not killed using the method <TT>SetThresholdImportantEnergy</TT> of
