7 The detector algorithm is implemented for the Muon Trigger in the AliRoot
8 framework. The main code is located in MUONTRGda.cxx and it runs in the MUON
9 Trigger MON (monitoring).
11 \section da_s1 The Muon Trigger Calibration
13 The main goal of the DA is the transfer of the modified configuration files to
14 the FES and to put them in the detector data base. In the current version, the
15 DA will modify only the global crate configuration.
17 The configuration files stored in the online DB are the following:
19 - MtgGlobalCrate-<version>.dat: contains the global crate information
20 - MtgRegionalCrate-<version>.dat: contains the regional crate information
21 - MtgLocalMask-<version>.dat: contains the local mask
22 - MtgLocalLut-<version>.dat: contains the local LUT
23 - MtgCurrent.dat: contains the name list of the above files with their version
24 and the flag for master/slave status on the DA
26 The copy onto the FES for the modified global masks is only done for any value of
27 the flag master/slave. The DA creates a file (ExportedFiles.dat) containing the
28 name of the files to be transfered by the shuttle. To be able to check the change
29 of version of one the files, another file is created containing the last current
30 list of configuration files: MtgLastCurrent.dat. The Muon trigger electronics can
31 run with two types of calibration. New: the two types can be done in the same
32 run containing a mixture of physics events with calibration events injected every
35 \subsection da_ss1 ELECTRONICS_CALIBRATION_RUN (calibration)
37 This procedure allows to check dead channels. The FET pulses are injected to the 21 kchannels.
39 The typical ECS sequence for calib is :
41 - Switch ON the electronics LV
42 - Load Configuration via the MTS package
44 - Data taking (typically 1000 events)
45 - The DA computes the occupancy of the global input entries, if a channel is not
46 responding in more than N% of the events (10% by default), it will be marked as dead
47 - The DA updates the global mask file accordingly, adds the file to the data base
48 and on the the File Exchange Server at the beginning of the next run.
50 Then the SHUTTLE process the ASCII files and store the configuration on the OCDB
52 \subsection da_ss2 DETECTOR_CALIBRATION_RUN (pedestal)
54 This procedure checks the noisy channels. Normal physics events are used.
56 The typical ECS sequence for calibration is :
58 - Switch ON the electronics LV
59 - Load Configuration via the MTS package
60 - Data taking (typically 1000 events)
61 - The DA computes the occupancy of the global input entries, if a channel is
62 responding in more than N% of the events (10% by default), it will be marked as
64 - The DA updates the global mask file accordingly, adds the file to the data base
65 and on the the File Exchange Server at the beginning of the next run.
67 Then the SHUTTLE process the ASCII files and store the configuration on the OCDB

71 You have a line command help. To have it just type :
76 ******************* MUONTRGda.exe usage **********************
77 MUONTRGda.exe -options, the available options are :
86 -p <thr value ped (deadc)> (default = 0.1)
87 -c <thr value cal (noise)> (default = 0.1)
88 -l <print level> (default = 0)
89 -s <skip events> (default = 0)
90 -n <max events> (default = 1000000)
91 -w <decoder warnings> (default = 0)
