Reverse-biased silicon p-n junction arrays using Silicon-On-Insulator technology have been proposed as microdosimeters. The performance of such detectors in boron neutron capture therapy (BNCT) is discussed. This work provides the first reported measurements using boron-coated silicon diode arrays as microdosimeters in BNCT. Results are in good agreement with measurements with gas proportional counters. Various boron-coating options are investigated along with device orientation effects. Finally, a 235U coating is tested to simulate the behavior of the device in a heavy-ion therapy beam.
已提出使用绝缘体上硅技术的反向偏置硅 p-n 结阵列作为微剂量计。讨论了此类探测器在硼中子俘获疗法（BNCT）中的性能。这项工作首次报道了使用涂硼硅二极管阵列作为 BNCT 中的微剂量计的测量结果。结果与气体正比计数器的测量结果吻合良好。研究了各种涂硼选项以及器件取向效应。最后，测试了 235U 涂层以模拟该器件在重离子治疗束中的行为。
