 Nine PCs are used for initialization (4 for the barrel, 4 for the endcap and 1 spare). These PCs are called pcatlmdtmdm1 to pcatlmdtmdm9. These machines may be accessed remotely (in the control room, there is a link from the Muons menu) and the login for these machines is:

  Once logged into the relevant PC, the DCS initialization panel should be displayed. It may be necessary to select the FE control panel. Then select all the sectors and sides to be initialized, and click Init All. If the initialization fails, click Init Failed and this command will only initialize chambers that are in the FAILED state. It is possible to initialize a single chamber by selecting it and then clicking on Initialize. The state will be updated on the general panel.

In the case of the Barrel, an additional check on the initialization may be performed in USA15 . Once a chamber has been initialized, a green LED should appear next to the corresponding MROD channel (top six connectors of the MROD boards in USA15). The correspondance between the chambers and the MROD channels are described in the manual "The MROD data format and the tower partitioning of the MDT chambers", available here.

 In the case of the Endcap, the green LEDs only turn on in the Configuration step of data acquisition.

For barrel sectors 3-6, the MRODs used are located in the top and middle crates of the first and third racks (counting from the entrance to USA 15). The first two inputs from the top are the BI chambers, the middle two BM chambers and the bottom two the BO chambers.

  Click on Get Partition, select the partition named muon_combined and then click Read In. Under the main menu, SpyIGUI opens a read-only copy of the Central TDAQ GUI.
Line: 178 to 179
 The OKS button opens the OKS Data Editor with the current partition to edit the configurations database. If settings in the database are changed and the TDAQ GUI is running, it is necessary to reload the database from the command toolbar of the TDAQ GUI (blue arrow on the right of the partition name) when all components are in NONE or INITIAL state. The MRS button opens the Message Reporting System (this is also available from the TDAQ panel). This monitor presents all the error messages from all components in the DAQ system and provides capabilities to filter messages.

In the monitoring tab, the OHP button opens the Online Histogram Presenter and OH opens a root TBrowser with the GNAM histograms (more information below under Monitoring). The DQMF button runs the Data Quality Monitoring Framework that consists of quality algorithms that applied to GNAM histograms (see below the section under Monitoring, and the DQMF Manual). The IS Monitor (Information Service Monitor) button shows detailed information for run parameters, run control, monitoring, and PMG. This feature is also available from the TDAQ GUI. The Data Flow (DF) key provides similar information as the TDAQ GUI Data Flow tab (see next section on TDAQ Panel).

 The IS Logger opens a GUI for IS. Do not click the icon! The IS Logger crashes often leaving a window which cannot be closed. Finally, the BUSY button opens the CTP Busy Panel.

A variety of tools are available to monitor chamber behavior and detect problems with the detector hardware or in data-taking. Histograms are produced online using GNAM and an online histogram presenter (OHP) facilitates their viewing. In addition, quality algorithms are applied to the GNAM output using DQMF, providing error and diagnostic messages. The monitoring information is displayed in separate interfaces.

GNAM

  GNAM is an Online Monitoring structure that allows monitoring of detector status and running conditions. For the MDTs during M5, GNAM has been implemented at the ROD level and provides histograms such as TDC and ADC spectra, hits per chamber and tube and so on. In order to setup GNAM it is necessary to provide chamber and run information. Before starting the run check and/or correct the files located in the directory:
Line: 249 to 249
 It is possible to automatically update the list of chambers utilized by GNAM with the autognamupdate script, located in atlasgw:~abelloni/autognamupdate/autognam.

DQMF and Online Histogram Presenter

 The Online Histogram Presenter (OHP) is a stand alone application displays the GNAM histograms, enabling the user to browse the histograms and display selected groups of histograms to be checked during the run. In order to configure OHP, in the main DAQ Panel select the file:

OHP Opt: -c /db/tdaq-01-08-03/muons/segments/DQM/MDT.ohpconf.m5.xml -e ohpcommands.
