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.

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