本文给出了CVD金刚石在300 MeV/c介子和24 GeV/c质子辐照下的耐辐照性的新结果。测量的电荷信号光谱进行比较，在几个照射水平与由模型计算的光谱。粒子的辐照会造成损害，导致电荷信号的降低。然而，测量结果和模型的结果都表明，对于跟踪器应用，该缺点至少部分地通过缩小电荷信号的分布曲线来抵消。因此，CVD金刚石跟踪器的效率受照射的影响小于平均电荷信号。
The paper gives new results on the radiation tolerance of CVD diamond for irradiation with 300MeV/c pions and 24GeV/c protons. The measured charge signal spectrum is compared at several irradiation levels with the spectrum calculated by a model. Irradiation by particles causes damage leading to a decrease of the charge signal. However, both the measurements and the outcome from the model show that for tracker applications this drawback is at least partly counterbalanced by a narrowing of the distribution curve of the charge signal. As a result, the efficiency of a CVD diamond tracker is less affected by irradiation than the mean charge signal.
