Revision as of 15:54, 23 June 2010

Comparing old and new runs with the old preamp. The pictures below show ADC amplitude histograms for first Fe55 and then 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.
Fe55
2100V - Fe55 - amplitude, old preamp, 2009 (left) and 2010 (right)

amplitude: old preamp, 55Fe, 50/50 Ar/CO2, 2100V, 2009
amplitude: old preamp, 55Fe, 50/50 Ar/CO2, 2100V, 2010

2100V - Fe55 - energy, old preamp, 2009 (left) and 2010 (right)
