7The detector algorithm is implemented for the Muon Trigger in the AliRoot framework.
ac5cb4a8 8The main code is located in MUONTRGda.cxx and it runs in the MUON Trigger MON (monitoring).

10\section da_s1 The Muon Trigger Calibration
11
ac5cb4a8 12The main goal of the DA is the transfer of the modified configuration files to the FES and to put them in the
13detector data base. In the current version the DA will modify the global crate configuration only (new).
14
3e42bf30 15The configuration files stored in the online DB are the following:
16
113ad708 17- MtgGlobalCrate-<version>.dat: contains the global crate information
18- MtgRegionalCrate-<version>.dat: contains the regional crate information
19- MtgLocalMask-<version>.dat: contains the local mask
20- MtgLocalLut-<version>.dat: contains the local LUT
21- MtgCurrent.dat: contains the name list of the above files with their version
ac5cb4a8 22 and the flag for master/slave status on the DA
3e42bf30 23
24The copy onto the FES for the modified local masks is only done when the flag is set to master for the DA.
ac5cb4a8 25The DA creates a file (ExportedFiles.dat) containing the name of the files to be transfered by the shuttle.
3e42bf30 26To be able to check the change of version of one the files, another file is created containing the last current
27list of configuration files: MtgLastCurrent.dat.
ac5cb4a8 28The Muon trigger electronics could run with two types of calibration. New: the two types can be done in the same
29run containing a mixture of physics events with calibration events injected every 50 seconds.

31\subsection da_ss1 ELECTRONICS_CALIBRATION_RUN (calib)
32
33This procedure allows to check dead channels. The FET pulses are injected to the 21 kchannels.
34
35The typical ECS sequence for calib is :
36
37- Switch ON the electronics LV
38- Load Configuration via the MTS package
39- Enable FET pulse
ac5cb4a8 40- Data taking (typically 1000 events)
41- The DA computes the occupancy of the global input entries, if a channel is not responding in N% of the case
42 (10% by default), it will be marked as dead
43- The DA updates the global mask file accordingly, adds the file to the data base and on the the File Exchange
44 Server at the beginning of the next run.
3e42bf30 45
46Then the SHUTTLE process the ASCII files and store the configuration on the OCDB
47
3e42bf30 48\subsection da_ss2 DETECTOR_CALIBRATION_RUN (ped)
49
50This procedure checks the noisy channels. A normal physics run is performed.
51
52The typical ECS sequence for calibration is :
53
54- Switch ON the electronics LV
55- Load Configuration via the MTS package
ac5cb4a8 56- Data taking (typically 1000 events)
57- The DA computes the occupancy of the global input entries, if a channel is responding in N% of the case (90%
58 by default), it will be marked as noisy
59- The DA updates the global mask file accordingly, adds the file to the data base and on the the File Exchange
60 Server at the beginning of the next run.
3e42bf30 61
62Then the SHUTTLE process the ASCII files and store the configuration on the OCDB
