lens thickness

Likelihood separation as a function of the NLak-layer's thickness of the lens.

  • 2017 prototype setup (plate +3-layer cylindrical lens +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
  • lens radii: r1 =33 mm, r2 = 25 mm
  • d - thickness of the NLak layer at the middle
  • lens8 design, with total thickness of 12 mm
