- 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 new fADC, preamp4 (left) and newest modified preamp (right) Blue histograms are tracked hits, runtimes were not equal. The fADC range is 4096.
Earlier new fADC results are on this page: New_fADC_with_cosmics
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
