• 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

• 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

  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.

...

 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

end2endBT.py

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.

...

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 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 a synchronized Run

This assumes that the user launches Run Control through the Run Control shortcut on the Desktop of lat-btserver.

Here is the (time ordered!) sequence of operatios for starting a non sysnchronized run;

...

1. Launch Run Control from the Run Control shortcut. At any time you can tell the application 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.
2. Make sure that the User is the Run Control Main GUI is properly set.
3. Make sure the front ends are powered up and the detectors are biased.
4. Select the end2endBT.py application.
5. Start the Ancillary DAQ by entering the command (into wkxglast1)

   No Format
   ACQmain

   You will be prompted to insert the number of events to be acquired and you'll have to properly start the run from a specific GUI (refer to the separate documentation for more details). Wait until the following message is prompted:

   Starting server socket on port 2345 -> waiting for a client...

6. Press the start button in thr Run Control main GUI.

 Starting a NON synchronized (standalone CU)  Run

This assumes that the user launches 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;
