19 | Please add to this README file all information concerning | |
20 | config files, simulation, digitalization, clusterization, | |
21 | reconstruction and macro analysis | |

29 | 1 single muon of 7 GeV/c in the MUON spectrometer | |
30 | acceptance will be simulated using geant3. | |
31 | Hit information will be store in the root file in the | |
32 | execution directory. | |
88cb7938 | 33 | If you want to change the option or to define a new directory |
34 | for hits, you have to do the following before: | |
35 | root [0] gAlice->SetConfigFunction("Config( \"/home/martinez/aliroot/work_NewIO/test/\" , \"box\" );"); | |
36 | ||
37 | ============================================================ | |
38 | How to run MUON Digitalization | |
39 | ============================================================ | |
40 | To process the digitalization of hits the AliRunDigitizer | |
41 | framework is used: | |
42 | ||
2058bf30 | 43 | AliRunDigitizer * manager = new AliRunDigitizer(1,1); |
44 | manager->SetInputStream(0,"galice.root"); | |
e6dd99fc | 45 | AliMUONDigitizerv1* dMUON = new AliMUONDigitizerv1(manager) |
2058bf30 | 46 | manager->AddDigitizer(dMUON); |
47 | manager->Exec("deb"); | |

138 | Tracking parameters, cuts, energy loss and physics processes | |
139 | ============================================================ | |
140 | Tracking parameters in MUON are automatically defined by GEANT | |
141 | MUON takes the default values of CUTs and physics processes | |
142 | defined by the Config files, except for the gas mixture medium | |
143 | of the tracking chambers. The CUT's and physics processes of | |
144 | the gas mixture medium is then defined in the galice.cuts file | |
145 | in the data directory. In particular ILOSS parameter MUST be | |
146 | equal unity (1) in order simulate a realistic energy loss | |
147 | distribution (mean value and fluctuations) in the active gas. | |
