The "tracker control" Graphical User Interface

Run as richtbuser@lbrichtb .

The tracker control GUI is started as follows:

cd /home/richtbuser/Public/tracker_tb2017
PATH=$PATH:. java -Djava.library.path=. -jar trackerControl.jar

From the main panel, press Get tracker ready for start to load settings into the modules and enable data taking.

On the trigger board GUI : check that the gates Tr-A and Tr-B are enabled and the triggers are stopped.

Press the Stop button followed Start to begin data acquisition. When Recording is ticked, Start will bring up a panel for automatic logbook entry. The tracker is ready to receive triggers as soon as you complete the log entry (include the Minidaq run number here). Now also start the Minidaq run.

On the trigger board GUI : now enable the triggers, and wait for data to be recorded. Once enough data is recorded, stop the triggers.

Press Stop on the tracker GUI to stop the run, and stop the Minidaq run.

Operating temperature interlock

Run as lhcbrich@lbrichtb.

The temperature interlock is managed by NI-visa. To find the device identifier, type NIvisaic in the terminal, and look for Serial Instrument Resources. The interlock will have an identifier of the format ASRL5::INSTR. Make a note of this identifier and close the NIvisaic.

SetupProject ROOT
cd /home/richtbuser/Public/itsdaq/interlock/
root -l 
> gSystem -> Load("./bin/libtilockdll")
> locker = new TILock("ASRL5::INSTR")
> locker -> PrintStatus()

NTC0-8 are connected to the modules. The temperatures should read 35 to 40 degrees Celsius.

ALERT! Switch off the tracker when any of the thermistors read >=41 degrees.

Switching the tracker on/off

ALERT! The enabling of the tracker low voltages and the silicon bias should be done with care, as there is a risk of overheating.

Run as lhcbrich@pclhcb182.

The digital board channel can be switched on/off regardless of what temperature the tracker is at.

First make sure that the nitrogen feed has flushed the box.

Then switch on the chiller and wait until the modules are cool (about 12-14 degrees C).

The TrackerLV1-4 can now be switched on.

The WinCC script performs the following sequence on "GO_READY".

1) Switch on silicon bias voltage : 150V and 3-4uA. Ramping should be slow, at 1V per second.

2) Switch on digital boards : 3V3 at 1.2A.

3) Switch on the 4 tracker LV channels : 5V and 2.2A per channel.

The tracker should then be configured by pressing Get tracker ready for start in the tracker control GUI.

The Online Display

Run as richtbuser@lbrichtb.

The online display is started as follows:

cd /home/richtbuser/Public/tracker_tb2017/online_display
java -jar pbw.jar

Data source should be set to http://localhost:7999/ from the tick down list.

Press "Go" and select the two trackers that appear. For each tracker, eight histograms and a 2D plot will appear.

Water cooling for the tracker

The chiller should be set to 8.0 degrees C. As this is well below the dew point, the box should be flushed with nitrogen before the cooling is enabled. Although precautions have been taken, it is also good to check during an access to the beam area that the patch panel doesn't get wet on the outside of the box due to condensation.
