R. Michaels, May 2015Recently, the PREX collaborators have been considering an idea to run PREX and C-REX back-to-back using a simplified target chamber geometry, see figures below. The idea came ultimately from Rolf, though the details here may differ.
Here are some pictures to illustrate the concept
Some merits of this idea:
At this stage, we need to do enough engineering and design work to know that the approach is feasible. After we have a feasibility check we'll make a better sketch and our collaboration can re-do the shielding and radiation simulations.
