|---|
| 9 | ------- |
|---|
| 10 | |
|---|
| 11 | This program is not a simulation. It prints the cross sections and stopping |
|---|
| 12 | power used by the standard electromagnetic package, via G4EmCalculator |
|---|
| 13 | which extracts these data from the PhysicsTables. |
|---|
| 14 | |
|---|
| 15 | The program can be used in batch or interactively. |
|---|
| 16 | |
|---|
| 17 | - compile and link to generate an executable |
|---|
| 18 | % cd geant4/examples/extended/electromagnetic/TestEm0 |
|---|
| 19 | % gmake |
|---|
| 20 | |
|---|
| 21 | - execute TestEm0 in 'batch' mode from macro files : |
|---|
| 22 | % TestEm0 TestEm1.in |
|---|
| 23 | |
|---|
| 24 | - Interactively, a typical sequence will be : |
|---|
| 25 | % TestEm0 |
|---|
| 26 | .... |
|---|
| 27 | Idle> /run/initialize |
|---|
| 28 | .... |
|---|
| 29 | Idle> /testem/det/setMat Silicon |
|---|
| 30 | Idle> /testem/phys/setCuts 100 um |
|---|
| 31 | Idle> /gun/particle e- |
|---|
| 32 | Idle> /gun/energy 10 MeV |
|---|
| 33 | Idle> /run/beamOn |
|---|
| 34 | |
|---|
| 35 | The last command triggers BuildPhysicsTable() and executes the program. |

| 38 | DirectAccess |
|---|
| 39 | ------------ |
|---|
| 40 | |
|---|
| 41 | DirectAccess is a small batch program which shows how to compute the same |
|---|
| 42 | basic data directly from the processes (indeed the models). |
|---|
| 43 | |
|---|
| 44 | To run it, change name in the first line on GNUmakefile before to compile. |
