基于PAMELA太阳高能粒子观测的GOES-13/15高能质子探测器的校准

Calibration of the GOES-13/15 high energy proton detectors based on the PAMELA solar energetic particle observations

Alessandro Bruno

摘要:

GOES航天器上的EPEAD和HEPAD仪器多年来一直用作太阳粒子强度监测器,对太阳进行观测并现场测量其对近地日地环境的影响。然而,重建的微分能谱的影响,大的不确定性与差的能量分辨率,小的几何因子和高污染的接受外的粒子。在这项工作中,来自PAMELA空间任务的高质量数据集用于校准GOES-13和-15上的EPEAD和HEPAD传感器的高能(>80 MeV)质子通道,使测量的光谱强度与PAMELA记录的光谱强度一致。建议的修正大大减少了GOES探测器响应的不确定性,从而提高了太阳高能粒子事件的光谱观测的可靠性。

英文摘要:

The EPEAD and HEPAD instruments on the GOES spacecraft have served over many years as monitors of the solar particles intensities, surveying the Sun and measuring in situ its effect on the near-Earth solar-terrestrial environment. However, the reconstruction of the differential energy spectra is affected by large uncertainties related to the poor energy resolution, the small geometrical factor and the high contamination by out-of-acceptance particles. In this work, the high quality data set from the PAMELA space mission is used to calibrate the high energy (>80 MeV) proton channels of the EPEAD and the HEPAD sensors onboard the GOES-13 and -15, bringing the measured spectral intensities in-line with those registered by PAMELA. Suggested corrections significantly reduce the uncertainties on the response of GOES detectors, thus improving the reliability of the spectroscopic observations of solar energetic particle events.
