A9.3 Chapter 3 - The Specific Problem (continued)

The detector itself is circular and has an effective response area of 1 cm2. As previously mentioned, the detector must be broken up into small DA's. Figure A9-8 shows how this has been done; at the center of each square is a starting coordinate.  The starting coordinate marks the point where the trajectories of the electrons for this particular element of area are to begin. For a listing of the coordinates of these starting points, see Appendix B.

Figure A9-8 The detector is broken up into finite area elements, and a starting coordinate assigned to each.
