Ray-tracing simulations of the iMott electron optics. (a) The HSA focal plane. This is the source for the iMott optics, with the electron trajectories in each point being inherently divergent in both E and θ directions. (b) The Au target. For better visibility, the broadening in (a) and (b) is shown artificially inflated by ×2 in both directions. (c, d) The position-sensitive eCCD1 (and the opposite eCCD3) and eCCD2 (eCCD4). The images are rendered into the E and θ coordinates using a n = 3 polynomial morphing transformation. |
