9f662337 30 @section intro Introduction:
31
32 This file contains a short overview of the FMD code. It is by no
33 means authoritative - only the code is good for that. However,
34 I'll try to explain things a bit here.
35
36 @section structure Structure:
37
38 There are 4 libraries build for the FMD. These are
39
40 - libFMDbase: This contains the basic stuff, like data classes and
41 managers.
42 - libFMDsim: This contains code used by the simulation only. That
43 includes the detector class AliFMD and it's derivatives. It
44 also contains the code for building the geometry, as well as the
45 digitisers and raw data writer.
46 - libFMDrec: Code needed for the reconstruction. This include the
47 reconstruction code itself, as well as a raw data reader.
48 - libFMDutil: This is a special library that contains various
49 utility classes for the FMD expert/developer/tester. It
50 includes code to read all data produced by the FMD, a simple
51 event display, and code to make fake calibration and alignment
52 data. This library is @e not loaded by aliroot
53 automatically. The user has to load it herself:
54 @code
55 gSystem->Load("libFMDutil.so");
56 @endcode
57 The content of these libraries is detailed more below.
f8616692 58
9f662337 59 @subsection base libFMDbase:
60
61 This currently (18th or March 2006) contains the classes
62
63 - AliFMDBaseDigit, AliFMDDigit, AliFMDSDigit: Base class for
64 digits, real digits, and summable digits. The are all data
65 classes that holds the ADC value(s) for a single strip.
66 - AliFMDBoolMap: A map of booleans, one for each strip.
67 - AliFMDUShortMap: A map of unsigned short integers, one for each
68 strip.
69 - AliFMDDetector, AliFMD1, AliFMD2, AliFMD3: 3 classes that holds
70 the parameters for each of the 3 FMD sub-detectors. These
71 derive from AliFMDDetector, and are managed by AliFMDGeometry.
72 Each of these also contains the translation from sensor
73 reference frame to global reference frame.
74 - AliFMDRing: Parameters for the FMD rings (inner and outer type).
75 These are managed by AliFMDGeometry.
76 - AliFMDGeometry: Manager of FMD geometry data. All code queries
77 this manager for geometry parameters, so that the data is always
78 consistent.
79 - AliFMDParameters: Manager of FMD parameters, like calibration
80 parameters. This class fetches data from CDB if necessary.
81 All code queries this manager for parameters, so that the data
82 is always consistent.
83 - AliFMDCalibPedestal, AliFMDCalibGain, AliFMDCalibSampleRate,
84 AliFMDAltroMapping: Containers of calibration parameters. These
85 correspond to the pedestal and its width, the gain of each
86 strip, the oversampling rate used in read-out, and the map from
87 hardware address to detector.
88 - AliFMDAltroIO, AliFMDAltroReader, AliFMDAltroWriter: Low-level
89 classes to do input/output on ALTRO formated buffers.
90
91
92
93 @subsection sim libFMDsim:
94
95 This currently (18th or March 2006) contains the classes
96
97 - AliFMDEdepMap: Cache of energy deposited and total number of
98 hits for each strip. The digitiser AliFMDDigitizer uses this to
99 store simulation data before making digits.
100 - AliFMDHit: A hit in the FMD active elements, as described by the
101 simulation back-end during transport.
102 - AliFMD, AliFMDv0, AliFMDv1: Simulation drivers for the FMD.
103 AliFMD is the base class. AliFMDv0 corresponds to a simulation
104 where no hits are created, but the material distribution is
105 right. AliFMDv1 is like AliFMDv0, except that hits are
106 produced.
107 - AliFMDGeometryBuilder: Build the FMD geometry in terms of TGeo
108 objects. The information for building the geometry is retrieved
109 from AliFMDGeometry.
110 - AliFMDBaseDigitizer, AliFMDDigitizer, AliFMDSDigitizer: Base
111 class for the digitisers. AliFMDDigitizer makes `real' digits
112 (AliFMDDigit) from hits, and AliFMDSDigitizer makes summable
113 digits from hits.
114 - AliFMDRawWriter: Writes a pseudo raw data file from the digits
115 created by the digitisers. It uses the AliFMDAltroMapping from
116 AliFMDParameters to make the mapping from detector coordinates
117 to hardware addresses.
118
119 @subsection rec libFMDrec:
120
121 This currently (18th or March 2006) contains the classes
122
123 - AliFMDReconstructor: Reconstruct (in a naiive way) the charged
124 particle multiplicity in the FMD strips. This also writes an
125 AliESDFMD object to the ESD files (that class is in libESD).
126
127 - AliFMDRecPoint: Reconstructed point in the FMD. These objects
128 are made AliFMDReconstructor.
129
130 - AliFMDRawReader: Classes to read raw data files.
131
e2c858f2 132 @subsection flow libFMDflow:
133
134 This library contains flow analysis code that works similar to
135 histograms.
136
137 @subsection ana libFMDanalysis:
138
139 This library contains analysis code.
140
141
9f662337 142 @subsection util libFMDutil:
143
144 This currently (18th or March 2006) contains the classes
145
146 - AliFMDInput, AliFMDInputHits, AliFMDInputDigits,
147 AliFMDInputSDigits, AliFMDInputRecPoints: Base class, and
148 concrete classes to read in FMD generated data. These provide a
149 simple and unified way of getting the data. Hooks are defined
150 to process hits, tracks, digits, and reconstructed points, as
151 well as geometry and ESD data. See for example the scripts
152 @c DrawHits.C, @c DrawHitsDigits.C, @c DrawHitsRecs.C, @c
153 DrawDigitsRecs.C in the @c FMD/scripts sub-directory.
154
155 - AliFMDDisplay: Simple event display for FMD data, including
156 hits, digits, reconstructed points and ESD data.
157
158 - AliFMDCalibFaker, AliFMDAlignFaker: Classes to write fake (or
f21fc003 159 dummy) calibration and alignment data.
160
9f662337 161
9b48326f 162 @section script Scripts
163
164 Most scripts live in @c FMD/scripts. The notiable exceptions are
165 @ref Simulate.C, @ref Reconstruct.C, and @ref Config.C
166
f8616692 167 @section quick Quick start
168
169 First, install ROOT. Then Install TGeant3:
170 @verbatim
171 > cd ~/
172 > mkdir alice
173 > cd alice
174 > cvs -d :pserver:cvs@root.cern.ch:/user/cvs login
175 Password: cvs
176 > cvs -d :pserver:cvs@root.cern.ch:/user/cvs co geant3
177 > cd geant3
178 > make
179 @endverbatim
180
181 Now you can install AliRoot
182 @verbatim
183 > cd ../
184 > cvs -d :pserver:cvs@alisoft.cern.ch:/soft/cvsroot login
185 Password: <empty>
186 > cvs -d :pserver:cvs@alisoft.cern.ch:/soft/cvsroot co AliRoot
187 > cd AliRoot
188 > export ALICE_TARGET=`root-config --arch`
189 > export ALICE=${HOME}/alice
190 > export ALICE_ROOT=${ALICE}/AliRoot
191 > export ALICE_LEVEL=new
192 > export LD_LIBRARY_PATH=${ALICE_ROOT}/lib/tgt_${ALICE_TERGET}:${LD_LIBRARY_PATH}
193 > export PATH=${ALICE_ROOT}/bin/tgt_${ALICE_TERGET}:${PATH}
194 > export G3SYS=${ALICE}/geant3
195 > make
196 @endverbatim
197
198 To simulate one event, do something like
199
200 @verbatim
201 > aliroot ${ALICE_ROOT}/FMD/Simulate.C
202 @endverbatim
203
204 To reconstruct the generated event, do
205 @verbatim
206 > aliroot ${ALICE_ROOT}/FMD/Reconstruct.C
207 @endverbatim
208
209 Now, open the file `AliESDs.root' in AliRoot, and browse through that.

241 @brief Forward Multiplicity Detector based on Silicon wafers.
242 This class is the driver for especially simulation.
243
244 The Forward Multiplicity Detector consists of 3 sub-detectors FMD1,
245 FMD2, and FMD3, each of which has 1 or 2 rings of silicon sensors.
246
247 This is the base class for all FMD manager classes.
248
249 The actual code is done by various separate classes. Below is
250 diagram showing the relationship between the various FMD classes
251 that handles the simulation

271 - AliFMD
272 This defines the interface for the various parts of AliROOT that
273 uses the FMD, like AliFMDSimulator, AliFMDDigitizer,
274 AliFMDReconstructor, and so on.
275 - AliFMDv0
276 This is a concrete implementation of the AliFMD interface.
277 It is the responsibility of this class to create the FMD
278 geometry.
279 - AliFMDv1
280 This is a concrete implementation of the AliFMD interface.
281 It is the responsibility of this class to create the FMD
282 geometry, process hits in the FMD, and serve hits and digits to
283 the various clients.
284 - AliFMDSimulator
285 This is the base class for the FMD simulation tasks. The
286 simulator tasks are responsible to implment the geoemtry, and
287 process hits.
288 - AliFMDReconstructor
289 This is a concrete implementation of the AliReconstructor that
290 reconstructs pseudo-inclusive-multiplicities from digits (raw or
291 from simulation)
292
293 Calibration and geometry parameters are managed by separate
294 singleton managers. These are AliFMDGeometry and
295 AliFMDParameters. Please refer to these classes for more
296 information on these.
