Revision as of 16:38, 17 June 2011
- 50/50 mixed Ar, CO2 at 60 sccm
- Recalibrated MFCs
- Outer plenum added to CDC prototype to prevent leaks
- 2050V
- Modified preamp (preamp4 with terminating resistors removed)
- Comparison of pre-production modified CDC HVB prototype from manufacturer with modified HVB from Fernando (the two should be identical)
Below: 55Fe: max amplitude histograms (left) and amplitude integrated over 96ns (right), new prototype HVB, cosmics rejected in software
Below: 55Fe: max amplitude histograms (left) and amplitude integrated over 96ns (right), Fernando's modified HVB, cosmics rejected in software
Below: Cosmics: max amplitude histograms (left) and amplitude integrated over 700ns (right), new prototype HVB
Below: Cosmics: max amplitude histograms (left) and amplitude integrated over 700ns (right), Fernando's modified HVB
