| 4 | In this directory you can find the test for Geant4 Solids with Optical Photons. |
|---|
| 5 | The test was created from a user application in order to test the replay |
|---|
| 6 | of the Solids. |
|---|
| 7 | |
|---|
| 8 | ============= |
|---|
| 9 | How it works : |
|---|
| 10 | ============= |
|---|
| 11 | - The Solid is situated in the center of the World Volume. |
|---|
| 12 | It can be choosen via macro command. |
|---|
| 13 | - The primary particle (e- of 20 veV) is shooting from Randomly Position on |
|---|
| 14 | the Shpere around the Solid to the center of the World Volume. |
|---|
| 15 | - This primary particle 'enters' in the Solid and create Optical Photons. |
|---|
| 16 | The boundary between Solid and World is declared as Boundary with Reflection. |
|---|
| 17 | If a optical Photon is going outside Solid, it is a Error. |
|---|
| 18 | This error is detected, warning or error message is printed. |
|---|
| 19 | This message also containts the information that can be useful for debugging: |
|---|
| 20 | -Position p and Direction v of the Point (Global Coordinates), were Error |
|---|
| 21 | is detected. |
|---|
| 22 | -Inside(p): |
|---|
| 23 | If p is Inside, the DistanceToOut(p,v,norm) is given |
|---|
| 24 | If p is Outside,the DistanceToIn(p,-v) is given |
|---|
| 25 | If p is On the Surface, both values are given. |
|---|
| 26 | |
|---|
| 27 | ===================== |
|---|
| 28 | How to run this test : |
|---|
| 29 | ===================== |
|---|
| 30 | |
|---|
| 31 | To build the application, first setup your Geant4 environmental variables, |
|---|
| 32 | do not forget to setup the visualisation part. |
|---|
| 33 | |
|---|
| 34 | and then do : make |
|---|
| 35 | |
|---|
| 36 | and to run it : AXPETDemonstrator run1.mac |
|---|
| 37 | |
|---|
| 38 | |
|---|
| 39 | ================================== |
|---|
| 40 | Via command line user can choose : |
|---|
| 41 | ================================== |
|---|
| 42 | |
|---|
| 43 | the solis : /mydet/SelectDetector nameOfSolid |
|---|
| 44 | the rotation: /mydet/RotateX angleInDegree |
|---|
| 45 | /mydet/RotateY angleInDegree |
|---|
| 46 | /mydet/RotateZ angleInDegree |
|---|
| 47 | In case of Error(Optical Photon escaping Solid) |
|---|
| 48 | warning or Abortion of the Run can be chosen. |
|---|
| 49 | It can be useful for large statistics. |
|---|
| 50 | Coomand for Abort Run : /mydet/AbortRun 1 |
|---|
| 51 | |
|---|
| 52 | ============ |
|---|
| 53 | The examples are given in vis.mac(shooting 30 e- in all solids) |
|---|
| 54 | ============ run1.mac(shooting 3000 e- in shoosen solid, Ellipsoid) |
|---|
| 55 | run2.mac(shooting 3000 e- in shoosen solid, |
|---|
| 56 | Shell=Subtraction of Spheres) |
