Here is a short introduction on how to launch and operate the Run Control for standard data taking. The following instructions assume that the e-logbook and the environmental monitoring are already running and - more important - the 28 V power supply which powers the CU is on.

The last section of this page is a step by step howto that can be used as a refernce during shifts.
Launching Run Control
Run Control comes in two different flavours, depending on the type of Run, and is launched by a double click on the proper icon on the Desktop of lat-btserver:
...
- CAL: this is done through the CAL tab in the Run Control main GUI. There's a button at the bottom of the tab for refreshing the BIAS DAC setting. The nominal value should be
No Format 0x5800
- TKR: this is done through the TKRtab in the Run Control main GUI. There's a button for refreshing the level of the TKR bias voltage. The nominal value shuold be around
No Format 100 V
Again: under normal conditions the bias voltages to the detectors should be on all the times and the shifters should not have to turn it on/off manually.

Selecting an application
The test application is choosen by pressing the Select Applicationbutton, which opens a file browser. Under normal circumstances the shifter should always select the application called
...
which, by the way, is the only test application into the default directory of the file browser. After the Open button is pressed, the file browser is closed and Run Control is ready to start.

Data taking: a step by step howto
This section is meant to be a practical reference for running data taking during the shifts. Refer to the previous sections for setails on the single items. We explicitly note that the The way a run is started, again, depends on wheter the CU is operated in syncro with the Ancillary Systems of by itself (see the Launch Run Control section).
Starting Starting a synchronized Run

ThisThis assumes that the user has launchedlaunches Run Control through the Run Control No Synch shortcut on the Desktop of lat-btserver. |
Here is the (time ordered!) sequence of operatios for starting a non sysnchronized run;
- Make sure that the hardware trigger is properly set (look at the NIM crate at the very top of the rack; the TRG->CU cable on the output of the TTL to NIM converter - third NIM module from the left - should be linked to the TRG->DAQ W/ DAQ VETO cable). Refer to the separate documentation for more details.
- Launch you launched Run Control from the right (Run Control No Synch) shortcut. You can tell by the titleAt any time you can tell the aplpication you're running (wheter it's normal or no synch) by the title of the X terminal popping up along with the Run Control main GUI.
- Make sure that the User is the Run Control Main GUI is properly set.
- Make sure the front ends are powered up and the detectors are biased.
- Select the end2endBT.py application.
- Press the start button in thr Run Control main GUI.
- Fill out ALL the fields in the GUI which is prompted to you for collecting the run information and press OK in the GUI itself.
