121 | <H2>3. Items for migration of the user code</H2> |
---|
122 | |
---|
123 | Listed here is some relevant information on developments included in this |
---|
124 | release, some of which may require migrations (mainly for users of advanced |
---|
125 | Geant4 features) in order to upgrade from release 9.1 to release 9.2. |
---|
126 | Note that for all users a full re-installation of libraries (or a full |
---|
127 | recompilation) and a recompilation of user applications is required. |

149 | new elastic scattering models are available for electrons, replacing the |

150 | old ones. The user may use in his/her physics list either the Screened |
---|
151 | Rutherford model or the Champion model; the models are alternatives and |
---|
152 | must not be used together.<BR> |
---|
153 | To use the Screened Rutherford model in the physics list, one should |
---|
154 | define the elastic process as follows: |
---|
155 | <PRE> |
---|
156 | typedef G4DNAProcess<G4CrossSectionElasticScreenedRutherfordHE, |

157 | G4FinalStateElasticScreenedRutherford> |

160 | G4FinalStateElasticBrennerZaider> |
---|
161 | ElasticScreenedRutherfordLE; |
---|
162 | </PRE> |
---|
163 | and register it as follows: |
---|
164 | <PRE> |
---|
165 | processManager->AddDiscreteProcess(new ElasticScreenedRutherfordLE("ElasticScreenedRutherfordLE")); |
---|
166 | processManager->AddDiscreteProcess(new ElasticScreenedRutherfordHE("ElasticScreenedRutherfordHE")); |

167 | </PRE> |
---|
168 | More details can be found in the advanced example <TT>microdosimetry</TT>.<BR> |

169 | To use the Champion model in the physics list, define the process as follows: |

221 | <LI>New <I>locator</I> classes and options are available for identifying the |

222 | intersection point of a charged particle in a field. These are Simple, Brent, |
---|
223 | and Multi-level and allow the user to investigate tradeoffs between increased |

225 | Multi-level is used by default to provide for robustness; the Brent method |

229 | <B>Detector description persistency</B> |

230 | <UL> |

231 | <LI>A new module for importing detector descriptions in ASCII text format |
---|
232 | is now part of Geant4. Such a description can be used as an alternative |
---|
233 | to GDML or other persistency techniques, and is provided with a corresponding set |
---|
234 | of UI commands.</LI> |
---|
235 | <LI>GDML: the GDML plugin module adds export capabilities, |
---|
236 | and thus replaces completely the external GDML module required in older versions |
---|
237 | of Geant4. The GDML schema has been upgraded to support missing |
---|
238 | solids and parameterisations. |
---|
239 | The new GDML-3_0_0 schema is now recommended.</LI> |

244 | <LI>The layout of the Qt interface, <TT>G4UIQt</TT>, which was introduced in |
---|
245 | release 9.1 as a <I>Beta</I> release, has been improved. It now supports both common |
---|
246 | versions of Qt: Qt3 and Qt4, and provides all the functionality of previous |
---|
247 | graphical user interfaces (such as Xm, Win32...). Also implemented a help |
---|
248 | widget to easily browse the entire Geant4 command system.</LI> |
---|
249 | <LI>Major Improvements have been made to the Qt visualization driver. This |
---|
250 | driver now includes all of the capabilties of the other OpenGL drivers, |
---|
251 | but adds additional controls to rotate, translate, zoom, to export to many |
---|
252 | graphics formats (jpeg, eps, ps, pdf) and to easily create visualization |
---|
253 | movies.</LI> |
---|
254 | <LI>The 2D drawing capability has been extended; added in previous release just |
---|
255 | for <TT>G4Text</TT>, it now also include <TT>G4Circle, |
---|
256 | G4Polyhedron, G4Polyline, G4Polymarker</TT> and <TT>G4Square</TT>. |
---|
257 | It allows placement in the 2D "screen window". Useful for tasks such as |
---|
258 | creating legends or logos that stay put on the screen while you otherwise |
---|
259 | rotate, translate or zoom the visualization.</LI> |

296 | <LI>Cubic Spline interpolation of <tt>dedx</tt> and cross section tables is |

298 | when varying transport parameters, such as cuts, of energy deposition of |
---|
299 | hadrons. The old variant of linear interpolation is available as an option.</LI> |
---|
300 | <LI>A new process, <TT>G4eMultipleScattering</TT>, specialized for simulation |
---|
301 | of <TT>e+ and e-</TT> multiple scattering has been added. |
---|
302 | This process in turn uses a new model, <TT>G4UrbanMscModel2</TT>, which is |
---|
303 | based on the <TT>G4UrbanMscModel</TT> of previous releases but has an |
---|
304 | improved sampling algorithm and has been retuned to experimental data. |
---|
305 | Several reference physics lists such as <TT>G4EmStandardPhysics</TT> now |

306 | use this new <TT>G4eMultipleScattering</TT> process.</LI> |

307 | <LI>A new class <TT>G4WentzelVIModel</TT> for multiple scattering of muons and |
---|
308 | hadrons is available as a prototype for validation.</LI> |
---|
309 | <LI>New bremsstrahlung model class, <TT>G4eBremsstrahlungRelModel</TT>, includes |
---|
310 | advanced description of LPM effect; it can be applied for electrons and |
---|
311 | positrons with <TT>E > 1 GeV</TT> and provides gamma spectra which agree |
---|
312 | well with thin-target experimental data.<BR> |
---|
313 | The density suppression effect in the old <TT>G4eBremsstrahlungModel</TT> |
---|
314 | has been reviewed and improved.</LI> |
---|
315 | <LI>The <TT>G4IonFluctuations</TT> model has been updated: at high energy |
---|
316 | it uses <TT>G4UniversalFluctuation</TT>, which provides Landau tail of |
---|
317 | fluctuations. |
---|
318 | At low energies it uses Gaussian distribution based on experimental data.</LI> |
---|
319 | <LI>The <TT>G4Cerenkov</TT> process now enforces a step limitation at the |
---|
320 | Cerenkov threshold and a new user defined step limitation provides for |
---|
321 | smoother X-ray emission.</LI> |
---|
322 | <LI>A new <TT>G4EmSaturation</TT> class is introduced for sampling of Birks |
---|
323 | saturation.</LI> |
---|
324 | <LI>A new <TT>G4ElectronIonPair</TT> helper class based on the ICRU'31 report has |
---|
325 | been added; it can be used for sampling electron/ion pairs in sensitive |
---|
326 | detectors.</LI> |
---|
327 | <LI>A new <TT>G4EmConfigurator</TT> class can be used for configuration of |
---|
328 | models in physics lists.</LI> |
---|
329 | <LI>Initialization of <TT>SubType</TT> has been added for all processes.</LI> |

349 | <LI>Bertini cascade: |

351 | <LI>Barrier penetration has been added to the Coulomb barrier.</LI> |

352 | <LI>A bug in the final state multiplicity sampling has been fixed, thereby |
