摘要

为鉴别击中搭载水稻种子的空间重离子

一种固体核径迹探测器（SSNTD）CR-39被用作“三明治”式探测系统的一部分

通过测量离子在CR-39中的射程R和蚀刻率V

就可得到斜率（dR/dV-1）。根据自建的一个数学模型R*=0.015AZ3.13V-1

可利用已知离子标定实验数据来拟合得到该模型的系数。为此

CR-39对C、Ne、Si、Ar和Fe离子的标定实验分别在中国科学院近代物理研究所的重离子研究装置（HIRFL-IMP）上和日本国立放射医学综合研究所的重离子医用加速器（HIMAC-NIRS）上进行。拟合得到了一个离子鉴别公式Z3.13=3.75×104+1.50（dR/dV-1）和一条标定直线。

Abstract

In order to identify the space heavy ions hitting loaded-seeds

the solid-state nuclear track detector (SSNTD) CR-39 was used as a part of a “sandwich” detecting system. By means of measurements of ion range R and etched rate V of CR-39

a slope (dR/dV-1) was acquired. Based on a mathematical model R* = 0.015AZ3.13V-1 estab- lished by ourselves

the coefficients of the model were fitted by using data from the calibration experiments of known ions. The calibration experiments of CR-39 for C

Ar and Fe ions were carried out at HIRFL-IMP in China

and HIMAC-NIRS in Japan. A fitted formula identifying ions Z3.13=3.75×104 +1.50(dR/dV-1) and a calibration line were obtained.
