First SVT results
This page shows our versions of the analysis results Maurizio posted at http://clasweb.jlab.org/wiki/index.php/First_SVT_results complete with ROOT source. I am shamelessly stealing his wiki code, too.
Details:
- Except for the proton and pion graph, we are using protons generated with momentum range 0.2 to 3.8 GeV, covering all angles uniformly
- The evio output is converted to ROOT output with evio2root
- The gemc commands to generate the two used data sets are:
$GEMC/gemc -GT=BST -PRINT_EVENT=10000 -BEAM_P="proton, 2.0*GeV, 0*deg, 0*deg" \ -SPREAD_P="1.9999*GeV, 180*deg, 360*deg" -SPREAD_V="(0.1, 0.1, 2.5)cm" \ -OUTPUT="evio, proton_500000.ev" -N=500000 -LUMI_P="e-, 11*GeV, 0, 0" \ -LUMI_V="(0, 0, -5)cm" -LUMI_EVENT="100, 124*ns, 2*ns" -USE_PHYSICSL=QGSP \ -HALL_MATERIAL=Vacuum -USE_QT=0
and
$GEMC/gemc -GT=BST -PRINT_EVENT=10000 -BEAM_P="pi+, 2.0*GeV, 0*deg, 0*deg" \ -SPREAD_P="1.9999*GeV, 180*deg, 360*deg" -SPREAD_V="(0.1, 0.1, 2.5)cm" \ -OUTPUT="evio, pion_500000.ev" -N=500000 -LUMI_P="e-, 11*GeV, 0, 0" \ -LUMI_V="(0, 0, -5)cm" -LUMI_EVENT="100, 124*ns, 2*ns" -USE_PHYSICSL=QGSP \ -HALL_MATERIAL=Vacuum -USE_QT=0
- Y vs x.jpg
y vs x global coordinate position of hits in the SVT detector. All layer required.
- Y vs x2.jpg
y vs x global coordinate position of hits in the SVT detector. 3 out of 4 SL required (always SL1).
- Y vs x3.jpg
y vs x global coordinate position of hits in the SVT detector. 3 out of 4 SL required.
- Theta.jpg
Theta distributions. black: all generated events. All other colors: require hits in increasing number of layers
- Edep vs p.jpg
Energy deposited versus generated momentum
Energy deposited versus strip number
- Nhits.jpg
Number of hits. Black: any hits. Red:
- Theta vs z 1hitperlayer.jpg
Theta vs generated vertex for hits in all the SVT layers
- Energy deposited.jpg
energy deposited.
- Phi vs z 1hitperlayer.jpg
phi versus z for hits in all the SVT layers
p versus phi for hits in all the SVT layers
- P vs theta 1hitperlayer.jpg
p versus theta for hits in all the SVT layers
