2. Irradiated 3D SINTEF sensors
Irradiated at Los Alamos LANCE facility in 2010 with 800 MeV protons
Integrated fluence is 1,2, and 5E15 neq/cm2
Total 6 sensors
Sensors seem fine but ROCs are dead except one
3D plaquettes placed in the environmental chamber
Only working sensors is 4E_B2-10_1
Fluence = 1E15 neq/cm2
4 electrodes
200 µm thick
