When Target T1 goes in and Accelerator side lights up( as viewed by scintillator Kelly) and Illyusha (when next to the beam exit window) also lights.

There is no Pb around T1.

Lets directionally shield Illyusha (when positioned next to the hallway) to determine how much lead to add around T1.

Area Conditions
800 \pm 130 pVs No shielding T1 in
No signals observed 1 Pb brick (2") shielding T1 in
