1) A weighted Monte-Carlo ray trace of particles exiting the target/magnet assembly for 
all primary beam energies showing:
  a) Where the scattered "good" events go.
  b) Where the un-scattered primary beam goes.
  c) Where the "photon" beam produced goes - and what it hits.
  d) Where the inelastic "sheet of flame" (the fan of in-elastics sweep out of the 
     target/magnet) goes and what structures it hits.

2) The proximity of significant magnetic material (support structures, other magnets, 
   shielding, etc) and some argument or calculation that these won't effect the 
   trajectories of charged particles discussed in (1) above.

3) A design for thin target exit window safety shielding (plastic or Al cover) that 
   has cut outs only for the places where the "good" events exit. Or a credible 
   argument that this cannot be done geometrically without compromising the measurement.

4) A clear written statement in the conduct of operation that they will never leave 
   the target/magnet energized with no experiment personnel on duty in either the 
   counting house or Hall A - 24/7 coverage when it is energized. With no ambiguous 
   wording or wiggle room on this one.
