CDC tracked cosmics

At 1950V, 50/50 gas:

Tracked cosmics - amplitude spectra for channel 7. In software, threshold = pedestal-mean + n * pedestal-width. n=10. Chamber is horizontal (left) and then tilted at 45 degrees (right).

Old preamp, n=10

old preamp, cosmics, 50/50 Ar/CO2, 1950V

old preamp, cosmics, 50/50 Ar/CO2, 1950V, 45 degrees

New preamp, n=10, ADC range halved (scale doubled)

new preamp, cosmics, 50/50 Ar/CO2, 1950V

new preamp, cosmics, 50/50 Ar/CO2, 1950V, 45 degrees

Zoom in on first pic (old preamp, n=10)

old preamp, cosmics, 50/50 Ar/CO2, 1950V, scale expanded

Repeat with n=8 Old preamp, n=8

old preamp, cosmics, 50/50 Ar/CO2, 1950V, n=8

old preamp, cosmics, 50/50 Ar/CO2, 1950V, 45 degrees, n=8

New preamp, n=8, ADC range halved (scale doubled)

new preamp, cosmics, 50/50 Ar/CO2, 1950V, n=8

new preamp, cosmics, 50/50 Ar/CO2, 1950V, 45 degrees, n=8
