Muon Event Display ‘d0ve’ Running Instructions

Muon Event Display ‘d0ve’ Running Instructions

This user guide explains how to run the d0ve (d0 visualization environment) executable, that has been set up to read raw data files on d0mino. If it doesn’t work, or if you have comments on how to improve these instructions, contact Paul Balm, extension 2177, email: p.balm@nikhef.nl, or Onne Peters, extension 2177, email: opeters@fnal.gov

Let me warn you before you start that you are going to need

the filename of the file on d0mino you want to display
the run configuration in which this file was taken

The run configuration consists of the crate numbers and types, and the module numbers and types for each crate, that were in the run when the data was taken.

Log on to d0mino.fnal.gov
Make sure that d0mino can open windows on your screen by setting the display variable correctly. This is not always necessary, for example if you use Exceed, this happens automatically.
Type: cd /prj_root/808/mtst_1/muondisplay

Type: setup n32
Type: setup D0RunII t00.89.00
Type: d0setwa

Type: setup xemacs

Transfer your datafile to d0mino. It doesn’t matter where you put it, as long as you know where it is.
Now you’ll have to edit a file to tell the display your filename.

Type: xemacs d0ve_muon/rcp/ReadEvent.rcp &

Edit the line that says string Inputfile and put your filename between the double quotes.
Save the file (by clicking ‘save’ of course)
If necessary, change the run configuration file to match the run configuration of the data:

Type xemacs cfg.dat &

All numbers are in hex, unless otherwise specified. The format is

…

and so on

One possible crate type is MUO_FE. Possible module types are PDT, MDT, MSC, MUO (the controller card), XXX (this is a module that will be skipped)

To start the display, type run

This should start the event display. Press the space bar to view the next event, and enter to automatically zap through all events. Press space again to stop. Use 1,2,3,4 for different projections, click on the image to change the reference point. Use the menu help option for more help on how to use the d0ve display.

To run the event display in online mode, where the events are not read from a data file but directly from the online system, the following changes have to be made:

type: xemacs d0ve_muon/bin/MuonDisplay.rcp &

comment out the line which says: RCP read = <d0ve_muon ReadEvent> by putting to slashes (‘//’) in front of it
uncomment the line which says:

// RCP read = <d0ve_muon ReadEventDaq>

by removing the two slashes

Save and exit
