Abstract
We have used silver-ion irradiation and proton irradiation to produce point-like and spherical defects in REBa2Cu3O7
coated conductors.We compare the resulting pinning landscape for
optimized fluences and show that proton irradiation gives a slightly
greater pinning enhancement at 20 K, but in the same samples
silver irradiation gives significantly better pinning enhancement at
65 K. We attribute this to the relative sizes of the defects and to
the distribution of defects resulting from the different ion collision
rates
