[edit] Cosmic Muons

A couple of screen shots of cosmic muons in the calorimeters with the pre-13.0.10 nightlies

• end-on
• roughly side-on

To run with cosmic muons using the 11.0.3 kit, I did the following:

• checked out MuonSpectrometer/MuonCommissioning/MuonCommExample/MuonCommExample-00-00-03
• checked out MuonSpectrometer/MuonCnv/MuonByteStream/MuonByteStream-01-01-14
• in MuonCommExample/cmt, I put MuonByteStream into the requirements, and ran gmake
• in MuonCommExample/run, I did get_files MuonCosmicTest_jobOptions.py
• I copied the data file the job options wanted for run 1008 to my local disk and edited the FullFileName line to point there instead of afs
• it ran OK
• then I tried adding HitDisplay by putting these lines near the end of my job options:

  theApp.Dlls += [ "HitDisplay" ]
  theApp.TopAlg  += [ "HitDisplay"]

• it seems to work
• I edited the job options to use Commissioning-Muon geometry instead of Rome-Initial
• select Control -> Launch -> HitDisplay -> MDT digits to see the digits as yellow cylinders
• select Control -> Launch -> Geometry -> Muons -> whatever you want to see, but be warned that if you show all the toroids and feet it gets difficult to find anything, and if you show the MDT chambers, you will need to change the display to wireframe if you want to see the digits inside them...
• now I am trying to run some segment building, but for that I need calibration files...

Some pictures of the MDT digits (the yellow cylinders are the tubes corresponding to digits):

• [[1]], [[2]], [[3]], [[4]], [[5]], [[6]], [[7]] (outlines of chambers only, plus yellow cylinders seen end-on for the digits, reasonably intuitive point of view - is it my imagination, or are some muons going through sideways in 6 and 7? Maybe I need to double-check that I am using the latest cabling map.)
• [[8]] (full geometry except the tubes without hits are hidden, turn your head sideways if you want to pretend you are standing in the pit)
• [[9]] (same view, geometry hidden)
• [[10]] (same event, tubes seen from the ends)
• [[11]], [[12]], [[13]], [[14]], [[15]] (more events)
