0104 Listed here is some relevant information on developments included in this
0105 release.
0106 Note that for all users a full re-installation of libraries (or a full
0107 re-compilation) and a re-compilation of user applications is required.

0112 <UL>
0113 <LI>Minimum required version of CMake to build Geant4 is 3.3.</LI>
0114 <LI>Due to the migration from POSIX threading to C++11 threading, enabling
0115     multi-threading on Windows for use with either static or dynamic
0116     libraries, the following migration is required:
0117     <UL>
0118     <LI>Any usage of <TT>G4THREADCREATE</TT> should pass a reference to an
0119         allocated <TT>G4Thread</TT> pointer.</LI>
0120         <UL>
0121         <LI><TT>G4THREADCREATE</TT> (previously a macro) is
0122             now a variadic template function that accepts an unlimited
0123             number of arguments to the function launched on the thread.</LI>
0124         <LI><TT>G4Thread t; G4THREADCREATE(&t, myfunction, myarg);</TT>
0125             is no longer valid</LI>
0126         <LI><TT>G4Thread* t = new G4Thread();
0127             G4THREADCREATE(t, myfunction, myarg);</TT> is required</LI>
0128         </UL>
0129     <LI><TT>G4MUTEX_INITIALIZER</TT>, <TT>G4MUTEXINIT</TT>, and
0130         <TT>G4MUTEXDESTROY</TT> are now empty macros and their usage is
0131         unnecessary and thus deprecated.</LI>

0139 <LI>The behaviour of G4Transportation and G4CoupledTransportation
0140     concerning the treatment of looping particles has been reviewed:
0141     <UL>
0142     <LI>From this release on, only stable particles are killed if they
0143         'loop', i.e.  take more than the maximum (default 1000) integration
0144         steps in one physics step; unstable particles are now propagated
0145         indefinitely.</LI>
0146     <LI>Warning exceptions with full details of the particle, location and
0147         volume are now generated for stable looping particles which are killed
0148         (as before, this only happens if their energy exceeds a threshold
0149         'warning' energy).
0150         In previous releases a short message with only energy and location
0151         was generated, and only for installations which did not use
0152         G4_NO_VERBOSE. Typically these warnings occur predominantly in vacuum
0153         or other low density media.</LI>
0154     </UL></LI>
0155 <LI>As before the killing of loopers and potential warnings are controlled by
0156     two energy thresholds and a step number parameter. Default settings imply:
0157     <UL>
0158     <LI><TT>100 MeV</TT> (warning energy): below this, tracks are killed
0159         silently.</LI>
0160     <LI><TT>250 MeV</TT> (important energy): above this, tracks are given
0161         multiple chances (10 physics steps).</LI>
0162     </UL>
0163     These settings are fully under user control. The new methods in
0164     G4PhysicsListHelper allow the user to select a set of low (or the above
0165     high) values of the 'looper' energy thresholds.
0166     Existing methods of G4[Coupled]Transportation can be used for fine-grained
0167     control of the parameter values.
0168     Additional information regarding how to reduce the incidence of looping
0169     particles is provided in an expanded section on Transportation in the
0170     Users Guide for Applications Developers.</LI>
0171 <LI>G4MagneticField has been corrected to no longer inherit from
0172     G4ElectroMagneticField;  this anomaly used to allow a user to provide a
0173     'full' EM field (mixed electric and magnetic), but obtain the force only
0174     from the B-field when using the equation created in the G4ChordFinder
0175     constructor. With this correction it is no longer possible to use the
0176     equation of motion for a pure magnetic field for the case of a mixed
0177     electromagnetic field. Instead the full chain of classes for equation
0178     of full EM field, steppers and driver must be used for the case of the
0179     'full' EM field.</LI>

0207 <LI>The default mode for Root n-tuple merging (in multi-threaded runs) is
0208     changed to row-wise in order to preserve an "event point of view" (the
0209     n-tuple rows) after merging. The output files written with this mode use a
0210     different data schema (organisations of TBranches and TLeaves) than

0236 <H2>4. New Developments and Capabilities </H2>
0237
0238 <B>General</B>
0239 <UL>
0240 <LI>Replaced POSIX threading with C++11 threading, enabling multi-threading
0241     on Windows for use with either static or dynamic libraries.</LI>
0242     <UL>
0243     <LI><TT>G4THREADCREATE</TT> is now a variadic template function
0244         (unlimited arguments) instead of a macro</LI>
0245     <LI><TT>G4THREADCREATE</TT> can be used outside of MT. In sequential
0246         mode, <TT>G4THREADCREATE</TT> will execute the function on the
0247         calling thread.
0248     </UL>
0249 <LI><TT>G4Mutex</TT> is now a typedef to <TT>std::mutex</TT>,
0250     even in sequential mode.
0251 <LI>Added <TT>G4RecursiveMutex</TT> typedef to
0252     <TT>std::recursive_mutex</TT>.</LI>
0253 <LI>Provided generic template functions <TT>G4TypeMutex&lt;T&gt;()</TT> and
0254     <TT>G4TypeRecursiveMutex&lt;T&gt;()</TT> to create and access static
0255     instances of mutexes without the need for declarations.</LI>
0256     <UL>
0257     <LI>When combined with <TT>G4AutoLock</TT>, this enables easy creation of
0258         class-specific locks, e.g.
0259         <TT>G4AutoLock lock(G4TypeMutex&lt;decltype(this)&gt;());</TT></LI>
0260     </UL>
0261 <LI><TT>G4AutoLock</TT> now inherits from <TT>std::unique_lock</TT>, even in
0262     sequential mode.</LI>
0263     <UL>
0264     <LI>In sequential mode, <TT>G4AutoLock</TT> does not lock upon construction,
0265         i.e. <TT>std::defer_lock</TT></LI>
0266     <LI>Added overloads to accept reference to mutex, in addition to previous
0267         form of a pointer to a mutex.</LI>
0268     </UL>
0269 </UL>
0270
0271 <B>Analysis</B>
0272 <UL>
0273 <LI>Switched the default Root ntuple merge mode to row-wise in analysis
0274     tools and added new <TT>G4RootAnalysisManager::SetNtupleRowWise(G4bool)</TT>
0275     function which can be used to override the defaults. </LI>
0276 <LI>Added "Boolean reset" argument in <TT>G4AnalysisManager::CloseFile()</TT>
0277     function, allowing to close a file without resetting data.</LI>
0278 </UL>
0279
0280 <B>Digitization &amp; Hits</B>
0281 <UL>
0282 <LI>Added new class G4StatAnalysis, a lightweight statistics class that
0283     calculates the mean, FOM, relative error, standard deviation, variance
0284     and other quantities. Compatible with usage in G4THitsMap and (new)
0285     G4THitsVector -- replacing <TT>G4THitsMap&lt;G4double&gt;</TT> with
0286     <TT>G4THitsMap&lt;G4StatAnalysis&gt;</TT> and can provide a quick
0287     implementation of accumulating statistics for scoring.</LI>
0288 <LI>Added new class G4THitsVector, a generic hits container compatible with
0289     G4THitsMap, that enables the underlying storage container to utilize a
0290     sequential container instead of a map (saving memory); additionally, it
0291     allows the underlying container to store data as non-pointer types
0292     (saving more memory).</LI>
0293     <UL>
0294     <LI>These containers are intended to be used at the G4Run level to
0295         accumulate data over the course of the run and it is not recommended
0296         for use at the event level -- a G4THitsMap is ideal at the event level
0297         due to the general sparsity of hits per index but at the run level,
0298         G4THitsVector becomes ideal with respect to memory usage as
0299         approximately 40% of the total available indices accumulate non-zero
0300         hits.</LI>
0301     <LI>See <I>DICOM2</I> and <I>ThreadsafeScorers</I> for usage examples,
0302         including demonstrations of G4THitsVector + non-pointer data storage
0303         and the new style of generic iteration over the hits container classes
0304         that is valid for both G4THitsMap and G4THitsVector (the previous form
0305         of iteration over G4THitsMap is still valid, and will remain valid,
0306         for G4THitsMap types).</LI>
0307     </UL>
0308 <LI>Introduced a new interface class, G4VScoreNtupleWriter, which allows
0309     automated storing of scorers hits with Geant4 analysis tools. Concrete
0310     implementations (G4ScoreNtupleWriter with associated messenger) are
0311     demonstrated in new provided extended/analysis examples.</LI>

0317     <A HREF="https://gitlab.cern.ch/VecGeom/VecGeom/">VecGeom Unified Solids
0318     Library</A> primitives, to replace the original Geant4 solids, as in the
0319     previous release. The path to an external installation of the VecGeom
0320     library (VecGeom version <TT>v01.01.00</TT>) should be specified.

0324 <LI>Reimplemented <TT>EstimateSurfaceArea()</TT> for approximate calculation
0325     of the surface area of a solid with new algorithm providing more
0326     accurate estimation without performance penalty.</LI>
0327 <LI>Introduced Bulirsch-Stoer method of integration, an alternative to
0328     Runge-Kutta based on the mid-point method.</LI>
0329 <LI>New G4InterpolationDriver field driver class using Runge-Kutta method

0357 <UL>
0358 <LI>For both Fritiof (FTF) and Quark-Gluon-String (QGS) string models,
0359     we have released the latest versions, which have been developed since
0360     the release 10.2 but have not been included in the two previous releases,
0361     10.3 and 10.4, to keep stable the simulation of hadronic showers
0362     (note that snapshots of these developments have been made available
0363     in previous beta releases: 10.3.beta, 10.4.beta and 10.5.beta).</LI>
0364 <LI>New tuning of the FTF model parameters, for both string formation
0365     and string fragmentation. Introduced smearing of delta-isobar mass and
0366     improved di-quark fragmentation into baryons in Lund string fragmentation.
0367     First implementation of rotating strings in FTF, at the level of string
0368     fragmentation, with introduction of Mt distribution of hadrons.
0369     Improved process probability parameterizations for Pi-Nucleon interactions;
0370     corrected calculation of nuclear residual excitation energy.</LI>
0371 <LI>Major revision of the QGS final-state model: implemented Reggeon cascading
0372     and "Fermi motion"; new algorithm for the determination of the kinematical
0373     properties of partons; improved formation of the residual nucleus.
0374     Improved cross-sections of K-meson - nucleon interactions in QGS: Pomeron
0375     and two non-vacuum exchanges are taken into account.
0376     Gamma-nucleon cross sections are also improved by tuning of parameters.
0377     Improved string fragmentation (G4QGSMFragmentation): new algorithm for
0378     last string decay a-la Lund is implemented; refined the algorithm to stop
0379     the fragmentation.
0380     Tuning the parameters related to both string formation and string
0381     fragmentation to improve the description of thin-target data.</LI>
0382 <LI>For both string models (FTF and QGS): first implementation of alpha
0383     cluster structure of carbon nuclei (affecting only hadron-Carbon
0384     interactions), according to P.Bozek et al., Phys.Rev.C90, 064902 (2014).</LI>
0385 <LI>For Bertini Cascade, extended strange pair production channels, and
0386     improved pion-quasideuteron reactions.</LI>
0387 <LI>Extended upper limit of applicability (from 1 to <TT>100 TeV</TT>) for the
0388     diffuse-elastic processes.</LI>
0389 <LI>New class for diffuse-elastic process, where the underlying physics model
0390     code has been revised and significantly improved in performance.</LI>

0463 <UL>
0464 <LI>Extended G4SeltzerBergerModel model with optional sampling tables for
0465     faster run time sampling of the emitted photon energy. Measuring 40-60%

0470 <UL>
0471 <LI>Both hadronic string models (FTF and QGS) describe generally better the
0472     thin-target data with respect to the previous versions.
0473     Moreover, the QGS model becomes competitive with the FTF model, for
0474     most thin-target observables for projectile kinetic energies above
0475     about 20 GeV.</LI>
0476 <LI>For the simulation of hadronic showers, both hadronic string models
0477     give higher energy response with respect to the previous versions,
0478     and consistently higher when compared with test-beam and collider data.
0479     We believe at least part of this is due to an underestimate with the Birks
0480     quenching factor which must be applied to the simulation in order to
0481     compare to measured data. The Birks coefficient is a phenomenological
0482     function of energy loss and not of energy deposit. It therefore neglects
0483     the effect of discrete delta ray production performed in Geant4.
0484     We therefore suggest re-fitting from data the Birks coefficient to the
0485     h/e ratio: energy response of a hadron (charged pion or proton) at a
0486     given energy with respect to the energy response of an electron of the
0487     same energy.</LI>

0898         added printing of the maximum energy and sum of energies of particles
0899         "saved". Added method <TT>SetHighLooperThresholds()</TT> to restore

0901         to 100 MeV - tracks below this are killed silently; important energy
0902         to 250 MeV - above this, tracks are given multiple chances). Default

0927     <LI>Correction in G4MagneticField to no longer inherit from
0928         G4ElectroMagneticField; this allowed a user to provide a full EM field,
0929         but obtain the force only from the B-field when using the equation
0930         created in the G4ChordFinder constructor.
0931         It is no longer possible to use the equation of motion for a pure
0932         magnetic field for the case of a mixed electromagnetic field. Instead
0933         the full chain of classes for equation of full EM field, steppers and
0934         driver must be used for the case of the 'full' EM field.</LI>
0935     <LI>Introduced Bulirsch-Stoer method of integration, an alternative to
0936         Runge-Kutta based on the mid-point method. A separate driver derived
0937         from G4VIntegrationDriver was needed, using specialisation of
0938         G4IntegrationDriver template class.</LI>
0939     <LI>Change in <TT>G4FieldManager::CreateChordFinder()</TT> to cope better
0940         with case where field argument is null.</LI>
0941     <LI>Fix for missing interface method in G4VIntegrationDriver; added method

0943         method must be defined in those derived driver classes which accept

2048         density.</LI>
2049     <LI>Introduced UI command <TT>/vis/drawLogicalVolume</TT>, synonymous with

2051         <TT>/vis/scene/add/logicalVolume</TT>. Includes overlap checking.</LI>
2052     <LI>Moved time window parameters from G4OpenGLStoredViewer to

2080         If physical-volume-name is "world" (the default), the top of the
2081         main geometry tree (material world) is added. If "worlds", the
2082         top of all worlds - material world and parallel worlds, if any - are
2083         added. Otherwise a search of all worlds is made.
2084         In the last case (a search of all worlds) all physical volume names are
2085         matched against the first argument of this command.</LI>
2086     <LI>G4VisManager: moved creation of top level commands to end so that

2089         guidance and parameters from <TT>/vis/scene/add/...</TT>.</LI>
2090     <LI><TT>/vis/scene/add/trajectories</TT>: avoid adding new model if one
2091         exists. If no trajectories model exists in the scene create a new one...
2092         else it already exists and there is no need to add a new one
