A drawing of the irradiation set-up can be found here: Proton_Irradiation

Simulation of the proposed LANL setup (by Heinz Vincke):

We assumed a 800MeV circular proton beam with uniform distribution (r=1cm)

Shielding the sensor:

This was the initial idea, which was abandonned.

here is a drawing of principle for shielding the FE-I3 chips under proton irradiation:

Cold Bump Bonding:

here the sensor would be irradiated and then would be bump bonded to the FE-I3 chip, with cold bump bonds.

Use a staggered bonding:
