<H2>6. Items for migration of the user code</H2>
|
|
|
|
Some migrations may be necessary for advanced uses of features in Geant4
|
|
in order to upgrade from release 8.0 to release 8.1. Note that a full reinstallation
|
|
of libraries (or a full recompilation) and a recompilation of user applications
|
|
is required.

Some improvements are introduced to multiple scattering.
|
|
As a consequence of these changes in the model, the following applies in
|
|
this release:
|
|
<UL>
|
|
<LI>the simulation of the back-scattering is improved;</LI>
|
|
<LI>the scattering in very thin layers is better than the one in version 8.0;</LI>
|
|
<LI>the tail of the angular distribution is now material dependent;</LI>
|
|
<LI>the visible energy in sampling calorimeters is less sensitive
|
|
to the value of the production threshold.</LI>
|
|
</UL>
|
|
It has been reintroduced the option to utilise smaller cuts in vicinity of
|
|
the geometrical boundary. The <I>subcutoff</I> option has been verified for
|
|
a number of simplified sampling calorimeter setups.
|
|
The simulation of ionization for ions was also improved. The data from NIST
|
|
databases for protons and helium ion and ICRU73 data for the carbon ion are
|
|
included for the first time. An interface to add user data on stopping
|
|
power for particular ion in particular media is provided.<BR>
|
|
A new version of the Synchrotron radiation is released.<BR>
|
|
The user interfaces allowing to set/access EM options, cross sections and
|
|
stopping powers are extended and improved.

|
|

|
|
<B>Hadronic physics: Bertini Cascade</B>
|
|
<P> </P>
|
|
In this release, the <TT>G4BERTINI_KAON</TT> conditional assembly flag has
|
|
been removed from the Bertini Cascade code, so that it is no longer needed
|
|
for the user to set them to instruct Bertini handling of strange particles.
|
|
|
|
<P> </P>
|
|
<B>Physics Lists</B>
|
|
<P> </P>
|
|
Physics lists are updated in order to utilize recent developments
|
|
in hadronic and electromagnetic physics. In particular, the more advanced
|
|
model sampling of capture of negatively charged hadrons at rest is used.
|
|
The new elastic process combining available models of elastic scattering
|
|
is introduced with significant improvement of elastic scattering on
|
|
hydrogen; the Binary and Bertini cascade developments are also utilized.

<LI>New example based on the IION application developed for

simulation of proton or ion beam interaction with a water target.

Different aspects of beam target interaction are demonstrated in the

example including logitudinal profile of energy deposition, spectra of
|
|
secondary particles, spectra of particles leaving the target. The
|
|
results are presented in a form of average numbers and histograms.</LI>
