论文摘要
这里研究了基于MAPBBR3钙钛矿单晶的质子检测器的性能和辐射耐受性。检测器可以在低施加的偏置电场（0.01 $ v/μm$）的剂量范围内监测通风率和剂量。由于dember效应，检测器也可以在零偏置下工作。检测器的暗电流被质子辐照到$ 7.3 \ times 10^{13} p/cm^2 $（1 mgy）后，降低至初始值的20％，但是，可以在室温下在数小时内将其回收。这些结果表明，这种检测器在质子治疗和质子成像等中具有有希望的应用。
The performance and radiation tolerance of the proton detector based on MAPbBr3 perovskite single crystal are investigated here with 3MeV protons. The detector can monitor fluence rate and dose quantificationally at a low applied bias electric field(0.01$V/μm$) within a dose range of 45 kGy. The detector can also be worked at zero bias due to the Dember effect. The dark current of the detector reduced to 20% of the initial value after being irradiated with protons to a total fluence of $7.3\times 10^{13} p/cm^2$ (1 MGy), however, it can be recovered at room temperature within hours. These results suggest that this kind of detector has a promising application in proton therapy and proton imaging etc.
