摘要
Abstract
Taking particles in space radiation environment as the research background,the space par-ticle detection system using silicon micro-strip sensor as the probe and integrated chip IDE3160 for sig-nal processing is developed.The system is designed by using silicon micro-strip detection array,which is composed of two silicon micro-strip sensors as the front-end probe,and using digital signal processing method to obtain the position of space particle incident and the energy deposited in the unit length(Lin-ear Energy Transfer,LET)in the silicon micro-strip.From the perspective of the physical mechanism in-ducing single particle effects,the physical effects produced by contrasting heavy ions and pulsed lasers in silicon semiconductors are different.Pulsed laser of 1.064µm was used to test the system,and good LET linearity results were obtained:The time required for data acquisition is 2.47 ms,the detectable LET threshold is about 0.1 MeV·cm2·mg-1 and the Pearson correlation coefficient is about 0.998,indicating that the system measurement is in good agreement with the theoretical design.The system has a wide dynamic range,good linearity,high integration,scalability and portability,and can be mounted on a va-riety of space exploration satellites.关键词
