keyword=Target status from physics replayIn order to study the status of the Pb+C and Bi+C targets, the variables rb.Raster.target.dir.y vs rb.Raster.target.dir.x (Position of the Raster at the target) have been ploted for most of the runs. 4 plots are made for each run (or group of runs):
1 ) With the whole number of events 2 ) With a cut in Emiss corresponding to the main Carbon peak 3 ) With a cut in Emiss corresponding to the outermost states of Pb or Bi, no carbon is expected within this cut 4 ) The large Emiss region, dominated by Pb or Bi.
It can be seen that the bismuth content from the C+Bi+C target is
irregular in the lower half from the very beginning of the experiment
(run 1324), and that the lead in C+Pb+C is gone (run 1308) in a large
area. The onset of the lead is in run 1209 and was gradually (and very
slowly) growing during the following runs.
Lead (Runs prior 1209)
Lead (Runs 1209-1216) Initial problems
Lead (Runs 1307-1308) Big problems
Bismuth (First run: 1324)
Bismuth (Better statistics: run 1326)
