CDC tracked and untracked cosmics 1950

The pictures below show ADC amplitude histograms for tracked and untracked cosmic ray data with 50/50 Ar/CO2 gas mixture (the maximum ADC amplitude for each event contributes one entry for that amplitude in the histogram) and energy spectra obtained by integrating the amplitude histograms.

1950V - cosmics - amplitude, old preamp (left) and new preamp (right) - ADC range is halved for new preamp
