Abstract

Experiment 8.1: E-T Detector Collection Efficiency. The solid angle and efficiency of a specific E-T detector for direct collection of BSEs is:
  1. (a)

    Area, A, of scintillator (cm2) = 1.5 cm2.

     
  2. (b)

    Distance, r, from specimen to scintillator (cm) = 4 cm.

     
  3. (c)

    Solid angle, Ω = A/r2 = 1.5/16 = 0.094 steradians.

     
  4. (e)

    For a specimen set normal to the beam (0° tilt), approximate take-off angle = 45°.
