New fADC with cosmics

• 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.

Struck fADC max amplitude histo for cosmics, mixed 50/50 at 60 sccm, 2050V, modified HVB

Cosmics, 2050V, drift time - untracked, new fADC (left) and Struck fADCs (right), same straw for both.
