9f662337 | 23 | @section intro Introduction: |
24 | ||
25 | This file contains a short overview of the FMD code. It is by no | |
26 | means authoritative - only the code is good for that. However, | |
27 | I'll try to explain things a bit here. | |
28 | ||
29 | @section structure Structure: | |
30 | ||
31 | There are 4 libraries build for the FMD. These are | |
32 | ||
33 | - libFMDbase: This contains the basic stuff, like data classes and | |
34 | managers. | |
35 | - libFMDsim: This contains code used by the simulation only. That | |
36 | includes the detector class AliFMD and it's derivatives. It | |
37 | also contains the code for building the geometry, as well as the | |
38 | digitisers and raw data writer. | |
39 | - libFMDrec: Code needed for the reconstruction. This include the | |
40 | reconstruction code itself, as well as a raw data reader. | |
41 | - libFMDutil: This is a special library that contains various | |
42 | utility classes for the FMD expert/developer/tester. It | |
43 | includes code to read all data produced by the FMD, a simple | |
44 | event display, and code to make fake calibration and alignment | |
45 | data. This library is @e not loaded by aliroot | |
46 | automatically. The user has to load it herself: | |
47 | @code | |
48 | gSystem->Load("libFMDutil.so"); | |
49 | @endcode | |
50 | The content of these libraries is detailed more below. | |
f8616692 | 51 | |
9f662337 | 52 | @subsection base libFMDbase: |
53 | ||
54 | This currently (18th or March 2006) contains the classes | |
55 | ||
56 | - AliFMDBaseDigit, AliFMDDigit, AliFMDSDigit: Base class for | |
57 | digits, real digits, and summable digits. The are all data | |
58 | classes that holds the ADC value(s) for a single strip. | |
59 | - AliFMDBoolMap: A map of booleans, one for each strip. | |
60 | - AliFMDUShortMap: A map of unsigned short integers, one for each | |
61 | strip. | |
62 | - AliFMDDetector, AliFMD1, AliFMD2, AliFMD3: 3 classes that holds | |
63 | the parameters for each of the 3 FMD sub-detectors. These | |
64 | derive from AliFMDDetector, and are managed by AliFMDGeometry. | |
65 | Each of these also contains the translation from sensor | |
66 | reference frame to global reference frame. | |
67 | - AliFMDRing: Parameters for the FMD rings (inner and outer type). | |
68 | These are managed by AliFMDGeometry. | |
69 | - AliFMDGeometry: Manager of FMD geometry data. All code queries | |
70 | this manager for geometry parameters, so that the data is always | |
71 | consistent. | |
72 | - AliFMDParameters: Manager of FMD parameters, like calibration | |
73 | parameters. This class fetches data from CDB if necessary. | |
74 | All code queries this manager for parameters, so that the data | |
75 | is always consistent. | |
76 | - AliFMDCalibPedestal, AliFMDCalibGain, AliFMDCalibSampleRate, | |
77 | AliFMDAltroMapping: Containers of calibration parameters. These | |
78 | correspond to the pedestal and its width, the gain of each | |
79 | strip, the oversampling rate used in read-out, and the map from | |
80 | hardware address to detector. | |
81 | - AliFMDAltroIO, AliFMDAltroReader, AliFMDAltroWriter: Low-level | |
82 | classes to do input/output on ALTRO formated buffers. | |
83 | ||
84 | ||
85 | ||
86 | @subsection sim libFMDsim: | |
87 | ||
88 | This currently (18th or March 2006) contains the classes | |
89 | ||
90 | - AliFMDEdepMap: Cache of energy deposited and total number of | |
91 | hits for each strip. The digitiser AliFMDDigitizer uses this to | |
92 | store simulation data before making digits. | |
93 | - AliFMDHit: A hit in the FMD active elements, as described by the | |
94 | simulation back-end during transport. | |
95 | - AliFMD, AliFMDv0, AliFMDv1: Simulation drivers for the FMD. | |
96 | AliFMD is the base class. AliFMDv0 corresponds to a simulation | |
97 | where no hits are created, but the material distribution is | |
98 | right. AliFMDv1 is like AliFMDv0, except that hits are | |
99 | produced. | |
100 | - AliFMDGeometryBuilder: Build the FMD geometry in terms of TGeo | |
101 | objects. The information for building the geometry is retrieved | |
102 | from AliFMDGeometry. | |
103 | - AliFMDBaseDigitizer, AliFMDDigitizer, AliFMDSDigitizer: Base | |
104 | class for the digitisers. AliFMDDigitizer makes `real' digits | |
105 | (AliFMDDigit) from hits, and AliFMDSDigitizer makes summable | |
106 | digits from hits. | |
107 | - AliFMDRawWriter: Writes a pseudo raw data file from the digits | |
108 | created by the digitisers. It uses the AliFMDAltroMapping from | |
109 | AliFMDParameters to make the mapping from detector coordinates | |
110 | to hardware addresses. | |
111 | ||
112 | @subsection rec libFMDrec: | |
113 | ||
114 | This currently (18th or March 2006) contains the classes | |
115 | ||
116 | - AliFMDReconstructor: Reconstruct (in a naiive way) the charged | |
117 | particle multiplicity in the FMD strips. This also writes an | |
118 | AliESDFMD object to the ESD files (that class is in libESD). | |
119 | ||
120 | - AliFMDRecPoint: Reconstructed point in the FMD. These objects | |
121 | are made AliFMDReconstructor. | |
122 | ||
123 | - AliFMDRawReader: Classes to read raw data files. | |
124 | ||
125 | @subsection util libFMDutil: | |
126 | ||
127 | This currently (18th or March 2006) contains the classes | |
128 | ||
129 | - AliFMDInput, AliFMDInputHits, AliFMDInputDigits, | |
130 | AliFMDInputSDigits, AliFMDInputRecPoints: Base class, and | |
131 | concrete classes to read in FMD generated data. These provide a | |
132 | simple and unified way of getting the data. Hooks are defined | |
133 | to process hits, tracks, digits, and reconstructed points, as | |
134 | well as geometry and ESD data. See for example the scripts | |
135 | @c DrawHits.C, @c DrawHitsDigits.C, @c DrawHitsRecs.C, @c | |
136 | DrawDigitsRecs.C in the @c FMD/scripts sub-directory. | |
137 | ||
138 | - AliFMDDisplay: Simple event display for FMD data, including | |
139 | hits, digits, reconstructed points and ESD data. | |
140 | ||
141 | - AliFMDCalibFaker, AliFMDAlignFaker: Classes to write fake (or | |
142 | dummy) calibration and alignment data. These derive from | |
143 | TTask. | |
144 | ||
9b48326f | 145 | @section script Scripts |
146 | ||
147 | Most scripts live in @c FMD/scripts. The notiable exceptions are | |
148 | @ref Simulate.C, @ref Reconstruct.C, and @ref Config.C | |
149 | ||
f8616692 | 150 | @section quick Quick start |
151 | ||
152 | First, install ROOT. Then Install TGeant3: | |
153 | @verbatim | |
154 | > cd ~/ | |
155 | > mkdir alice | |
156 | > cd alice | |
157 | > cvs -d :pserver:cvs@root.cern.ch:/user/cvs login | |
158 | Password: cvs | |
159 | > cvs -d :pserver:cvs@root.cern.ch:/user/cvs co geant3 | |
160 | > cd geant3 | |
161 | > make | |
162 | @endverbatim | |
163 | ||
164 | Now you can install AliRoot | |
165 | @verbatim | |
166 | > cd ../ | |
167 | > cvs -d :pserver:cvs@alisoft.cern.ch:/soft/cvsroot login | |
168 | Password: <empty> | |
169 | > cvs -d :pserver:cvs@alisoft.cern.ch:/soft/cvsroot co AliRoot | |
170 | > cd AliRoot | |
171 | > export ALICE_TARGET=`root-config --arch` | |
172 | > export ALICE=${HOME}/alice | |
173 | > export ALICE_ROOT=${ALICE}/AliRoot | |
174 | > export ALICE_LEVEL=new | |
175 | > export LD_LIBRARY_PATH=${ALICE_ROOT}/lib/tgt_${ALICE_TERGET}:${LD_LIBRARY_PATH} | |
176 | > export PATH=${ALICE_ROOT}/bin/tgt_${ALICE_TERGET}:${PATH} | |
177 | > export G3SYS=${ALICE}/geant3 | |
178 | > make | |
179 | @endverbatim | |
180 | ||
181 | To simulate one event, do something like | |
182 | ||
183 | @verbatim | |
184 | > aliroot ${ALICE_ROOT}/FMD/Simulate.C | |
185 | @endverbatim | |
186 | ||
187 | To reconstruct the generated event, do | |
188 | @verbatim | |
189 | > aliroot ${ALICE_ROOT}/FMD/Reconstruct.C | |
190 | @endverbatim | |
191 | ||
192 | Now, open the file `AliESDs.root' in AliRoot, and browse through that. | |

223 | @brief Forward Multiplicity Detector based on Silicon wafers. | |
224 | This class is the driver for especially simulation. | |
225 | ||
226 | The Forward Multiplicity Detector consists of 3 sub-detectors FMD1, | |
227 | FMD2, and FMD3, each of which has 1 or 2 rings of silicon sensors. | |
228 | ||
229 | This is the base class for all FMD manager classes. | |
230 | ||
231 | The actual code is done by various separate classes. Below is | |
232 | diagram showing the relationship between the various FMD classes | |
233 | that handles the simulation | |

253 | - AliFMD | |
254 | This defines the interface for the various parts of AliROOT that | |
255 | uses the FMD, like AliFMDSimulator, AliFMDDigitizer, | |
256 | AliFMDReconstructor, and so on. | |
257 | - AliFMDv0 | |
258 | This is a concrete implementation of the AliFMD interface. | |
259 | It is the responsibility of this class to create the FMD | |
260 | geometry. | |
261 | - AliFMDv1 | |
262 | This is a concrete implementation of the AliFMD interface. | |
263 | It is the responsibility of this class to create the FMD | |
264 | geometry, process hits in the FMD, and serve hits and digits to | |
265 | the various clients. | |
266 | - AliFMDSimulator | |
267 | This is the base class for the FMD simulation tasks. The | |
268 | simulator tasks are responsible to implment the geoemtry, and | |
269 | process hits. | |
270 | - AliFMDReconstructor | |
271 | This is a concrete implementation of the AliReconstructor that | |
272 | reconstructs pseudo-inclusive-multiplicities from digits (raw or | |
273 | from simulation) | |
274 | ||
275 | Calibration and geometry parameters are managed by separate | |
276 | singleton managers. These are AliFMDGeometry and | |
277 | AliFMDParameters. Please refer to these classes for more | |
278 | information on these. | |
