Effects of proton irradiation on the superconducting properties of sintered MgB₂ samples were investigated as a function of proton fluence at fixed energy. All experimental data suggest that critical current densities, irreversibility field and creep activation energy are enhanced because of the complex disorder, which mainly affects the grain boundaries, brought on the crystalline structure by the energetic protons.

质子通量对MgB ₂超导性质的影响。用高能质子照射

研究了质子辐照对MgB ₂烧结样品超导性能的影响，它是质子注量在固定能量下的函数。所有实验数据均表明，由于高能质子带给晶体结构的复杂无序（主要影响晶界），从而提高了临界电流密度，不可逆场和蠕变活化能。
