- 50/50 mixed Ar, CO2
- Recalibrated MFCs
- Outer plenum added to CDC prototype to prevent leaks
- New modified HVB
- 2050V
- Comparison of modified preamp (preamp4 with terminating resistors removed) and its predecessor (preamp4)
Below: cosmics with newest modified preamp (left) and preamp4 (right) Blue histograms are tracked hits, runtimes were not equal.
Below: 55Fe spectra with preamp 4 and Struck ADCs set to half-range, 550mV
Below: 55Fe spectra with newest preamp (preamp4 minus terminating resistors) and Struck ADCs set to full-range, 1.1V
