<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 advanced uses of
|
|
features in Geant4) in order to upgrade from release 9.0 to release 9.1.
|
|
Note that a full re-installation of libraries (or a full recompilation) and
|
|
a recompilation of user applications is required.
|
|
|
|
<P> </P>
|
|
<B>Geometry</B>
|
|
<P> </P>
|
|
The revision of <TT>G4TessellatedSolid</TT> required a name change for some
|
|
public methods. User code making explicit use of these methods should migrate
|
|
accordingly.
|
|
|
|
<P> </P>
|
|
<B>Low Energy Electromagnetic physics</B>
|
|
<P> </P>
|
|
The prototype interfaces of beta-version <TT>G4DNA*</TT> processes have been
|
|
replaced by a unique process. Prototype user code is required to migrate; in
|
|
principle the migration is limited to replacing <TT>typedef</TT> statements.
|
|
|
|
<P> </P>
|
|
<B>Standard Electromagnetic physics</B>
|
|
<P> </P>
|
|
The <TT>G4Cerenkov</TT> process was changed from being an <TT>AlongStep</TT>
|
|
process to a <TT>PostStep</TT> process. Custom user physics-lists that
|
|
include <TT>G4Cerenkov</TT> must be changed accordingly:
|
|
<PRE>
|
|
pmanager->AddContinuousProcess(theCerenkovProcess);
|
|
</PRE>
|
|
to:
|
|
<PRE>
|
|
pmanager->AddProcess(theCerenkovProcess);

pmanager->SetProcessOrdering(theCerenkovProcess,idxPostStep);

<B>Hadronic physics</B>

<P> </P>
|
|
Gamma level file warnings in <TT>G4NuclearLevelManager</TT> have been
|
|
suppressed, so if an isotope has no data, no warning will be issued.
|
|
To turn them on again, set the pre-compiler flag <TT>GAMMAFILEWARNING</TT>
|
|
as follows:
|
|
<PRE>
|
|
CPPFLAGS += -DGAMMAFILEWARNING
|
|
</PRE>
|
|
and re-build the library in
|
|
<TT>processes/hadronic/models/de_excitation/photon_evaporation</TT> of Geant4.
|
|
|
|
<P> </P>
|
|
<B>Fast Parameterised Simulation</B>
|
|
<P> </P>
|
|
The process <TT>G4FastSimulationManagerProcess</TT> (<TT>G4FSMP</TT>) can be
|
|
used for trigger fast simulation models. These can be attached either to a region of the primary 'mass'
|
|
geometry or to a region of a parallel (ghost) geometry.<BR>
|
|
In the first case, the user has to attach an instance of the <TT>G4FSMP</TT>
|
|
process as a <TT>PostStep</TT> process to particles having a fast simulation
|
|
model in the mass geometry; this remains unchanged.<BR>
|
|
A change is required in the second case, of a ghost geometry: the <TT>G4FSMP</TT> process now must be attached as an <TT>AlongStep+PostStep</TT>
|
|
process to particles having fast simulation models bound to regions of the
|
|
ghost geometry.<BR>
|
|
The <TT>AlongGetPhysicalInteractionLength()</TT> method of the <TT>G4FSMP</TT>
|
|
process must be placed second-to-last in this case (i.e. after the Multiple
|
|
Scattering, but before the Transportation processes). An example is given in
|
|
the physics-list defined in <TT>examples/novice/N05</TT>.

<H2>4. New Developments and Capabilities </H2>
|
|
|
|
<B>Geometry</B>
|
|
<UL>
|
|
<LI>Introduced new navigation for phantoms and similar regular
|
|
structures. The new algorithm provides fast navigation
|
|
and no memory overhead for voxels phantoms and similar geometries.
|
|
An option is available to skip volume boundaries, when the volumes on either side hold the same material. The example in <TT>extended/medical/DICOM</TT> has been
|
|
revised to demonstrate the usage of the new parameterisation required and the corresponding navigation. In addition it
|
|
enables comparison against existing algorithms, including the nested parameterisation (which had reduced memory overhead) and the older 3D optimisation.</LI>
|
|
</UL>
|
|
|
|
<B>GDML detector description persistency</B>
|
|
<UL>
|
|
<LI>A plugin-module for GDML can be installed optionally in Geant4. This replaces the dependency on the external GDML (GDML-2.X series) library. The new
|
|
module includes all the features supported in the old GDML library for
|
|
importing GDML descriptions, except for handling of parameterised volumes
|
|
and material optical properties. (These will be added in a future version
|
|
of the new plugin.) It remains possible to use the old external
|
|
GDML library, if needed.</LI>

found in <I>S. Chauvie et al., "Geant4 physics processes for
|
|

<LI>Extended applicability of the Binary cascade. <TT>G4BinaryCascade::Propagate()</TT> method is first released. This allows
|
|
the use of the Binary cascade to transport the remnants of a high energy collision, as it has become model in the high energy
|
|
framework (<TT>G4TheoFSGenerator::SetTransport()</TT>). This feature is
|
|
aimed for expert use currently, as validation is starting.<br>
|
|
The binary cascade can now be used for pions, benefiting from a bug fix for
|
|
incident pions; validation is in progress.</LI>
|
|
<LI>The first, alpha release of the new INCL (Liege) cascade module is included. This will be an alternative to the
|
|
Binary and Bertini cascades, are already offered in Geant4, and valid up
|
|
to <TT>3 GeV</TT>. It has been converted from the Fortran implementation and its validation is ongoing.</LI>
|
|
<LI>First, alpha release of new QMD (quantum molecular dynamics) nucleus-nucleus
|
|
interaction code. Its validation is ongoing.</LI>
|
|
<LI>High precision neutrons: G4NDL 3.12 data set is now released. This uses
|
|
JENDL entries for Cd isotopes, and adds four new elements with their
|
|
corresponding isotopes: <TT>Hg</TT>, <TT>Ra</TT>, <TT>Br</TT>, and
|
|
<TT>La</TT>.</LI>

<B>Physics Lists</B>

<P> </P>
|
|
<P>
|
|
Several new physics lists are offered, providing new configurations or new
|
|
modeling options. Feedback via the Hypernews Forum on physics lists is welcome.
|
|
The new physics lists are:
|
|
<UL>
|
|
<LI><B>FTFP_BERT</B> and <B>QGSC_BERT</B>: both of these reduce the use of
|
|
parameterized modeling. For proton, neutron, pion and kaon induced
|
|
inelastic hadronic interactions the parameterized model is not used.</LI>
|
|
<LI><B>QGSP_DIF</B> and <B>QGSP_BERT_DIF</B>: for diffractive scattering of
|
|
proton and neutron at high energies a diffractive scattering model
|
|
provided by CHIPS is used.</LI>
|
|
<LI><B>QGS_BIC</B> and <B>FTF_BIC</B>: offering new developments of
|
|
Binary cascade. For more details, see the detailed notes.</LI>
|
|
</UL>
|
|
|
|
<B>Command-based scoring</B>
|
|
<UL>
|
|
<LI>The user can
|
|
use this new ability to score on an arbitrary three-dimensional scoring mesh, using only new user commands. No user code needs be
|
|
written to apply the scoring. It utilises a parallel world making the mesh geometry
|
|
can be independent of the mass geometry. An arbitrary number of physics
|
|
quantities to be scored and filters affecting these scorers can be assigned
|
|
to the mesh. After scoring has been applied (i.e. after the run), the user
|
|
can visualize the score map and also dump scores into a file. Relevant
|
|
UI commands are listed in the Application Developers Guide, and the new
|
|
<TT>extended/runAndEvent/RE03</TT> example demonstrates their usage.</LI>
|
|
<LI>Command-based scoring is in Beta release; commands and methods are subject
|
|
to modification in future releases. Feedback will be greatly appreciated.</LI>

<LI>Fixed problem reported by ATLAS of high energy collision of <TT>sigma+</TT>
|
|
and a nucleon producing a high energy backward proton. This problem has
|
|
been in the hadronic code since the beginning and was due to incorrectly
|
|
selecting evaporated nucleons as leading particles. At <TT>1 TeV</TT>
|
|
incident energy, this type of event occurred 0.5% to 1% of the time when
|
|
the HEP models are used. After the fix, no high energy backward nucleons
|
|
are observed, with the effect that such events will not exist to mimic
|
|
exotic reactions.</LI>
|
|
<LI>Bug fixes and completed implementation of theory in <TT>G4PreCompoundModel</TT>
|
|
and <TT>G4Evaporation</TT> have produced a 10-15% increase in neutron flux
|
|
for <TT>2.5 GeV/c</TT> protons incident on <TT>Pb</TT>.</LI>
|
|
<LI>Correct time is now set for secondaries, instead of global time. This will
|
|
primarily affect neutron times for users of the HP neutron package.</LI>
|
|
<LI>An angular distribution bug in Bertini cascade has been fixed. Previously,
|
|
double differential cross sections showed an excess of events at high
|
|
energy and small to medium scattering angles. The fix removes this by
|
|
using an <TT>exp(t)</TT> distribution for nucleon-nucleon scattering above
|
|
<TT>2.8 GeV</TT>. This will result in only a small reduction of average
|
|
particle energy in the secondaries.</LI>
|
|
<LI>Bug fix in quasi-elastic scattering may cause shower shapes to be a bit
|
|
shorter and wider when using QGSC/QGSP physics lists.</LI>

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

In case either of these reported energy is significant, we recommend to

<LI>Modified behaviour of <TT>G4Navigator</TT>

Before only a simple, quick estimation of the starting point's safety was done, using the

last available value of the isotropic safety (from the Navigator).
|
|
Now the navigator is called to compute this safety. This improves the value
|
|
and avoids roundoff issues. It gives better stability in comparisons with

|
CoupledTransportation. The costs are additional calls to the Navigator.

A new method <TT>EnableShortStepOptimisation</TT> controls this.
