|---|
| 10 | * This UI-command base scoring is still in beta release and * |

| 14 | * In particular for the cylindrical scoring mesh, we are * |

| 15 | * aware of rather frequent warning messages issued by the * |
|---|
| 16 | * G4Navigator for the zero-length steps. I believe the results * |
|---|
| 17 | * is correct, but we appreciate the user's patient for this * |
|---|
| 18 | * messy warning messages. It is identified that if a track * |
|---|
| 19 | * enters at exactly the center of the top/bottom circlic face * |
|---|
| 20 | * exactly along the local z-axis of the scoring cylinder, this * |

| 25 | 1. Introduction |
|---|
| 26 | |
|---|
| 27 | This example demonstrates how to use UI-command base scoring. |
|---|
| 28 | It create parallel world(s) for defining scoring mesh(es). |
|---|
| 29 | |
|---|
| 30 | Since this UI-command base scoring is preliminary, this |
|---|
| 31 | functionality is not provided by default. To get it included, |
|---|
| 32 | the pointer to G4ScoringManager must be accessed. The access |
|---|
| 33 | to the static method G4ScoringManager::GetScoringManager() |
|---|
| 34 | activate this functionality. |
|---|
| 35 | |
|---|
| 36 | 1.1 Geometry and primary particle |
|---|
| 37 | |
|---|
| 38 | It has just one water box in the world volume filled by air. |
|---|
| 39 | No detector in the mass geometry. Particle gun shoots a gamma |
|---|
| 40 | into the water box. |
|---|
| 41 | |
|---|
| 42 | 1.2 Physics |
|---|
| 43 | |
|---|
| 44 | The physics list is mostly identical to exampleN03. It does not |
|---|
| 45 | have hadronics. |
|---|
| 46 | |
|---|
| 47 | 2. Macro files |
|---|
| 48 | |
|---|
| 49 | "run1.mac" through "run4.mac" macro files should be used |
|---|
| 50 | independently. Each macro file create its own scoring parallel |
|---|
| 51 | world(s). "vis.mac", "drawSlices.mac" and "drawCylinderSlices.mac" |
|---|
| 52 | are used internally. Each macro should work for both interactively |
|---|
| 53 | and batch, but interactive mode is advised for better visualization. |
|---|
| 54 | |
|---|
| 55 | IMPORTANT: DO NOT use more than one of these macro files in one |
|---|
| 56 | execution of this example. |
|---|
| 57 | |
|---|
| 58 | 3. RE03UserScoreWriter |
|---|
| 59 | |
|---|
| 60 | G4ScoringManager has a default score writer which dumps every |
|---|
| 61 | entry of one quantity of a mesh for all quantities of the mesh |
|---|
| 62 | one by one in CSV format. To alternate the file format the user |
|---|
| 63 | can implement his/her own score writer deriving from G4VUserScoreWriter |
|---|
| 64 | base class and set it to G4ScoringManager. To demonstrate this, |
|---|
| 65 | RE03UserScoreWriter is included in this example. To use this |
|---|
| 66 | alternative writer, un-comment its instantiation in RE03.cc. |
