Proton damage
Quote from Lecomte et al., NIM A 587 (2008) 266-271, "Comparison between high-energy proton and charged pion induced damage in PbWO4 calorimeter crystals":
"...at eta = 2.2 and for an integrated luminosity of 5.10**5 pb-1, the expected induced absorption coefficient corresponds to the one observed for a proton fluence of 10**13 p/cm2 (Fig. 15 in Ref. [3])."

Note from F Nessi, 3 Apr 2014, "...the star densities for CMS, that are used to scale the damage observed in proton and pion irradiations, come from a full FLUKA propagation of minimum bias events in CMS. Thus, high-energy neutrons are included already. Just the low energy ones that fall below the FLUKA thresholds, are not."
