| 113 | <H2>3. Items for migration of the user code</H2> |
---|
| 114 | |
---|
| 115 | Listed here is some relevant information on developments included in this |
---|
| 116 | release, some of which may require minor migrations for advanced uses of |
---|
| 117 | features in Geant4 in order to upgrade from release 8.1 to release 8.2. |
---|
| 118 | Note that a full re-installation of libraries (or a full recompilation) and |
---|
| 119 | a recompilation of user applications is anyhow required. |
---|

---|
| 122 | <B>Standard Electromagnetic physics</B> |
---|
| 123 | <P> </P> |
---|
| 124 | Some improvements were introduced to multiple scattering, which provide |
---|
| 125 | improved results for large angle scattering; better particle transport near |
---|
| 126 | geometry boundaries and less cut dependence for sampling calorimeters |
---|
| 127 | (see details in Physics Reference Manual).<BR> |
---|
| 128 | A new class <TT>G4hMultipleScattering</TT> has been created to provide faster |
---|
| 129 | simulation of hadron transport. This class uses the same multiple scattering |
---|
| 130 | model configured to reduce step limitation. It is used for hadrons and ions |
---|
| 131 | in most physics lists.<BR> |
---|
| 132 | A new module polarization is introduced for simulation of circular polarized |
---|
| 133 | beams of <TT>e+-</TT> and <TT>gamma</TT>.<BR> |
---|
| 134 | The change in response of calorimeters, due to the revision of the |
---|
| 135 | multiple scattering process (in its default configuration) is expected |
---|
| 136 | to be less than 1%. Larger differences are seen in the revised |
---|
| 137 | configuration, which does not apply most step limitations for electons and |
---|
| 138 | that is used in the QGSP_EMV physics list. |

---|
| 151 | such it is now built as part of the kernel libraries by default. The number of |
---|
| 152 | libraries has been reduced to two; it is now possible to use them together |
---|
| 153 | with shared libraries (or DLL on Windows) and global libraries. |
