lens 2 vs. lens 6 RMI

Likelihood separation and the photon yield for 2 layer vs. 3 layer cylindrical lens.

  • 2017 prototype setup (plate +33 degree prism)
  • realistic beam profile
  • pions and protons @ 7 GeV/c
  • time resolution 150 ps
  • time-imaging reconstruction with full-simulated pdfs
  • time=[0,40] ns
  • 3LC according RMI Rev. B except lens radii : r1 =33 mm, r2 = 24 mm
