Correlation between distances wire-cathode and coincidence rates 03/12/2003


We try to find a correlation between distances wire-cathode and coincidence rate from the mapping of profile2.
From measurements of distances we calculate the distance wire-cathode in corrispondence of each ortogonal strip for each wire, then following we plot coincidence rate versus distances.


Profile 2


  • The best thing it should be to find high rates for low distances and viceversa, while from our measurements we can only say that for low distances we could have high rates, but also low rate.
  • We don't see high rates for high distances.
  • Probably low distances are not all causes of high rates.
