Revision as of 14:04, 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)
