XFT Trigmon plots

How to check XFT plots on TrigMon root files?


See the

Consumer home page.

Consumer how-to web page.
This has useful notes about where to find the output and root files. I summarise how to find recent root files in the instructions below.

Consumer web page about how to view the output of consumer monitors
This has the advice about how to start up HistoDisplayMain and how to monitor data from the current run (what the CO is looking at).

Consumer Status web page
This tells you the machine and port (eg b0dap70:9092) and is what you should type in the HistoDisplayMain file field to look at the current run.

1. Login to any b0dap** machine

2. source ~cdfsoft/cdf2.cshrc

3. setup cdfsoftb0

4. HistoDisplayMain & to bring up the consumer framework GUI

5A. For current data, type the hostname and port number that you see for TrigMon from the Consumer Status web page eg "b0dap70:9092" into the file field. Go to step 7.

5B. For previous runs, click Select Other ROOT file in AddInputStream Panel

6A. For runs from last 24 hours, type /data1/consumer/results/TrigMon/TrigMonNNNNNNaa.root in the file field. where NNNNNN is the run number.

6B. For earlier runs, type /cdf/cdf-cf-data1/cdf_cf/results/TrigMon/TrigMonNNNNNNaa.root in the file field.

7. Click Open to open this file.

8. Two folders, TrigMon and Slides will appear on the GUI. Double click on the Slides folder.

9. Double-click on the XFT canvases - look for any errors in the discrepancy plots, any new hot or cold spots and any dips in the track occupancy.

10. You can look at these plots for the XTC, but dead wires that are masked by the finder are not taken into account. Double click on the TrigMon folder, then the XFTTriggerMonitor2 folder, then on the XTC folder, then on the Operator folder. Double-click on the XTC: Delayed Occupancies, then Prompt & Delayed, then Prompt. The occupancy and expectation are on the left hand side. There are two kinds of errors: missed XTC hits and phantom XTC hits. Missed XTC hits are when there is a COT hit but no XTC hit. Phantom hits are when there is not a COT hit but there is a XTC hit.

Hints:

Deselect "Automatic(al) update" so that you can pull the plots around to see the scales without the canvas being updated a few seconds later. This also stops the slideshow.

Make sure the true scale on the right-hand colour bar is not hidden by the histogram (very annoying ROOT feature). Use the mouse to resize the plot.

To open a new root file, hit the reset button on the GUI, then alter the name in the file field and click open.
