| 3 | To run the detector, type in the terminal: |
||
| 4 | |||
| 5 | root -l examples/load.cxx |
||
| 6 | |||
| 7 | As default, this shows the light guide, draws 30 rays (out of 10000 simulated), and shows the statistics. |

| 10 | Main files: |
||
| 11 | |||
| 12 | 1) src/guide.cpp |
||
| 13 | The plane, ray, guide and detector classes and functions. Class DetectorParameters holds all the variables needed for the guide and detector: |
||
| 14 | a - the lower (smaller) side of the light guide |
||
| 15 | b - the upper side |
||
| 16 | M - magnification ratio = b/a |
||
| 17 | d - the length of the light guide |
||
| 18 | activeDetector - the side of the photon detector (SiPM) |
||
| 19 | |||
| 20 | All surfaces are refractive, the probability of reflection is calculated using the Fresnel equations: |
||
| 21 | n1 - the refractive index of the upper surface (default: air) |
||
| 22 | n2 - r. i. inside the detector (default: borosilicate glass K9 1.53 @ 404 nm) |
||
| 23 | n3 - r. i. on the lower surface (default: optical cement) |
||
| 24 | |||
| 25 | 2) src/raySimulator.cpp |
||
| 26 | One or multiple ray simulator functions. |
||
| 27 | |||
| 28 | 3) src/userFunctions.cpp |
||
| 29 | The main user functions. Draws rays in specified pattern (single, grid or isotropic) and calculates acceptance of the light guide. |
||
