Preamp 4: Comparison of cosmic data with original preamp
From GlueXWiki
The pictures below show ADC amplitude histograms for cosmic ray data with 50/50 Ar/CO2 gas mixture. The maximum ADC amplitude for each event contributes one entry (at that amplitude) in the histogram. These compare data taken using the old and new preamps - the "old" preamp is the original one and the "new" preamp is Preamp4, described in Table 2 row 2 of GlueX-doc-1364 and labelled 27.
