Description

We describe our measurements of the depletion voltage and change in effective doping concentration obtained from capacitance measurements after irradiation and annealing of four types of silicon diodes: n- and p-type in both Float Zone (Fz) and Magnetic Czochralski (MCz) silicon. The samples were irradiated with 800 MeV protons to fluences reaching 1.1x10$^{15}$ n$_{eq}$/cm$^2$ and then annealed in several time steps at 60~$^\circ$C. The results were then fit using the Hamburg Model to extract annealing behavior constants.
