Real life results from prototype 2100V 50/50 Ar/CO2 with scintillators horizontal, cosmics not limited to 90o
Drift time (- offset) in ns
First max in signal amplitude
Integrated signal


Garfield for 3GeV muons at 90o to straw
Drift time (- offset)
First max in signal amplitude
Integrated signal


Garfield for 400MeV/c protons at 45o to straw
Drift time (- offset)
First max in signal amplitude
Integrated signal


Garfield for 400MeV/c protons at 23o to straw
Drift time (- offset)

Integrated signal


Same prototype run, lower hit threshold (3sigma) 2100V 50/50 Ar/CO2
Max amp
Integrated signal
Integrated signal for hits with maxamp < 90
Integrated signal for hits with maxamp < 60
Same prototype run, 2100V 50/50 Ar/CO2, look at low amplitude hits and exclude events identified (in another file) as having a higher amplitude hit later on
Max amplitude for 3 sigma hit threshold, blue: all 3sigma hits, pink: excluded later hits over 5 sigma
Integrated signal for 3 sigma hit threshold, blue: all 3sigma hits, pink: excluded later hits over 5 sigma
Max amplitude for 2 sigma hit threshold, blue: all 2sigma hits, pink: excluded later hits over 3 sigma
Integrated signal for 2 sigma hit threshold, blue: all 2sigma hits, pink: excluded later hits over 3 sigma
