keyword=Photos of added shielding on BB beamline sideFigure 1: 1" thick Teflon(?) plate shielding from low-E electrons from dump/downstream beamline. This is _not_ the heavy plastic, it's fairly light... (Added Nov. 13)
Figure 2: Lead (blue) and ??? (grey, not Pb) blocks roughly centered at bealine height. They are as far forward as possible, front edge is a few inches back from the front edge of the BB platform. (Added Nov. 11)
Figure 3, 4: Lead bags shielding from beamline closer to target. The
upstream bag has a neighbor on the other side of the black 'wing' on BB,
doubling the thickness to ~4" total. The downstream bag is by itself.
