Damage Function D(E) with an Example

Displacement damage functions for NIEL scaling in silicon

D(E)(1MeV n) ~ 100 MeV mb

=>NIEL=2.144 keV cm2/g

D(E)(24GeV p) ~ 60 MeV mb

=>NIEL=1.265 keV cm2/g

• have to apply 1.7 times as many 24GeV protons to reach same damage as with 1MeV neutrons

• count only for silicon !

1 MeV n

24 GeV p
