摘要:

本文介绍了一种测试CMOS传感器与耐辐射的像素单元设计的80 keV和100 keV的电子的响应的研究结果。对于20微米像素,测量的点扩散函数在100 keV下为(13.0+/- 1.7)微米,在80 keV下为(12.1 +/- 1.6)微米。结果与Geant-4和专用电荷收集模拟预测的值吻合良好。

英文摘要:

This paper presents the results of a study of the response of a test CMOS sensor with a radiation tolerant pixel cell design to 80 keV and 100 keV electrons. The point spread function is measured to be (13.0+/- 1.7) microns at 100 keV and (12.1 +/- 1.6) microns at 80 keV, for 20 micron pixels. Results agree well with values predicted by a Geant-4 and dedicated charge collection simulation.
