radii scan for pbf2

Likelihood separation as a function of the lens parameters for different polar angles of the prototype.

  • 2017 prototype setup (bar +3-layer shperical lens +33 degree prism)
  • realistic beam profile
  • pions and protons @ 7 GeV/c
  • time resolution 200 ps
  • time-imaging reconstruction with full-simulated pdfs
  • time=[0,40] ns
