近地轨道囚禁粒子模型的比较
A Comparison of Trapped Particle Models in Low Earth Orbit
摘要:
众所周知,空间辐射对固态高能传感器构成严重问题。因此,辐射模型在对探测器的辐射损害、工作周期、性能和寿命进行预防性评估方面发挥着关键作用。在HERMES-SP任务的背景下,我们提出了我们的调查AE 8/AP 8和AE 9/AP 9规范的近地俘获辐射环境。我们考虑不同的圆形低地球轨道。捕获的粒子通量,从该辐射区域的地图计算,估计占空比在不同的通量阈值。结果也与发表的结果进行了比较,在原位测量。
英文摘要:
Space radiation is well-known to pose serious issues to solid-state high-energy sensors. Therefore, radiation models play a key role in the preventive assessment of the radiation damage, duty cycles, performance and lifetimes of detectors. In the context of HERMES-SP mission we present our investigation of AE8/AP8 and AE9/AP9 specifications of near-Earth trapped radiation environment. We consider different circular Low-Earth orbits. Trapped particles fluxes are obtained, from which maps of the radiation regions are computed, estimating duty cycles at different flux thresholds. Outcomes are also compared with published results on in-situ measurements.
