Revision as of 15:32, 11 April 2011
- 50/50 mixed Ar, CO2
- Recalibrated MFCs
- Outer plenum added to CDC prototype to prevent leaks
- New preamp
- New HVB
Cosmics, 2050V, max amplitude histograms, new fADC with unmodified HVB (left), with modified HVB (center) and Struck fADCs with modified HVB (right), same straw for each.
NB different x axis scale, full scale is 4096 for both ADCs.
Cosmics, 2050V, drift time - untracked, new fADC (left) and Struck fADCs (right), same straw for both.
