20 | // Forward Multiplicity Detector based on Silicon wafers. This class |
| 21 | // contains the base procedures for the Forward Multiplicity detector |
| 22 | // Detector consists of 5 Si volumes covered pseudorapidity interval |
| 23 | // from 1.7 to 5.1. |
| 24 | // |
| 25 | // This is the base class for all FMD manager classes. |
| 26 | // |
| 4347b38f |
27 | // The actual code is done by various separate classes. Below is |
| 28 | // diagram showing the relationship between the various FMD classes |
| 29 | // that handles the geometry |

| 54 | // |
| 55 | // |
| 56 | // * AliFMD |
| 57 | // This defines the interface for the various parts of AliROOT that |
| 58 | // uses the FMD, like AliFMDDigitizer, AliFMDReconstructor, and so |
| 59 | // on. |
| 60 | // |
| 61 | // * AliFMDv1 |
| 62 | // This is a concrete implementation of the AliFMD interface. |
| 63 | // It is the responsibility of this class to create the FMD |
| 64 | // geometry, process hits in the FMD, and serve hits and digits to |
| 65 | // the various clients. |
| 66 | // |
| 67 | // It uses the objects of class AliFMDSubDetector to do the various |
| 68 | // stuff for FMD1, 2, and 3 |
| 69 | // |
| 70 | // * AliFMDRing |
| 71 | // This class contains all stuff needed to do with a ring. It's |
| 72 | // used by the AliFMDSubDetector objects to instantise inner and |
| 73 | // outer rings. The AliFMDRing objects are shared by the |
| 74 | // AliFMDSubDetector objects, and owned by the AliFMDv1 object. |
| 75 | // |
| 76 | // * AliFMDPolygon |
| 77 | // The code I lifted from TGeoPolygon to help with the geometry of |
| 78 | // the modules, as well as to decide wether a hit is actually with |
| 79 | // in the real module shape. The point is, that the shape of the |
| 80 | // various ring modules are really polygons (much like the lid of a |
| 81 | // coffin), but it's segmented at constant radius. That is very |
| 82 | // hard to implement using GEANT 3.21 shapes, so instead the |
| 83 | // modules are implemented as TUBS (tube sections), and in the step |
| 84 | // procedure we do the test whether the track was inside the real |
| 85 | // shape of the module. |
| 86 | // |
| 87 | // * AliFMD1, AliFMD2, and AliFMD3 |
| 88 | // These are specialisation of AliFMDSubDetector, that contains the |
| 89 | // particularities of each of the sub-detector system. It is |
| 90 | // envisioned that the classes should also define the support |
| 91 | // volumes and material for each of the detectors. |
| 92 | // |
