论文摘要

Sun Cube One(请参阅)是向意大利航天局进行A/B期研究的12U立方体任务,该研究将研究伽马和X射线通量和紫外线(UV)太阳能发射,以支持在Sun-Ear-Ear-Earth Coothaction和Leo的空间天气中进行支持。更详细地,请参见主要目标是测量从软X到伽马射线能量范围的耀斑发射,并利用完整的磁盘成像器有效载荷,以280 nm的频率监测Fraunhofer MG II Doublet的太阳能。伽马和X射线通量将通过前所未有的时间分辨率进行研究,并采用多波长的方法研究,这要归功于硅光电二极管和基于硅光电峰(SIPM)的检测器的综合使用。耀斑光谱将通过相同的有效载荷从KEV探索到MEV的能量范围,并且具有高达10 kHz的节奏,并且具有单光子检测能力,以揭示太阳能弹性的来源。能量范围涵盖了GOOS卫星使用的相同带,这是耀斑幅度定义的标准带。同时,SIPM探测器与闪烁器结合使用,可以覆盖伽马能范围内的非热BREMSSTRAHLUNG发射。鉴于其紫外线成像能力,请参见将是支持太阳能活动的详细研究的关键空间资产,尤其是与紫外线辐射有关,该辐射与地球大气层的上层强烈相互作用,并且与空间安全性有关,包括人类空间探索领域。紫外线有效载荷的主要目标是在两个不同的时间尺度上研究MG II频段中太阳紫外线发射的演变:沿太阳周期的年度变化和耀斑事件期间的瞬态变化。

The Sun cubE onE (SEE) is a 12U CubeSat mission proposed for a phase A/B study to the Italian Space Agency that will investigate Gamma and X-ray fluxes and ultraviolet (UV) solar emission to support studies in Sun-Earth interaction and Space Weather from LEO. More in detail, SEE's primary goals are to measure the flares emission from soft-X to Gamma ray energy range and to monitor the solar activity in the Fraunhofer Mg II doublet at 280 nm, taking advantage of a full disk imager payload. The Gamma and X-ray fluxes will be studied with unprecedented temporal resolution and with a multi-wavelength approach thanks to the combined use of silicon photodiode and silicon photomultiplier (SiPM) -based detectors. The flare spectrum will be explored from the keV to the MeV range of energies by the same payload, and with a cadence up to 10 kHz and with single-photon detection capabilities to unveil the sources of the solar flares. The energy range covers the same bands used by GOES satellites, which are the standard bands for flare magnitude definition. At the same time SiPM detectors combined with scintillators allow to cover the non-thermal bremsstrahlung emission in the gamma energy range. Given its UV imaging capabilities, SEE will be a key space asset to support detailed studies on solar activity, especially in relation to ultraviolet radiation which strongly interacts with the upper layers of the Earth's atmosphere, and in relation to space safety, included in the field of human space exploration. The main goal for the UV payload is to study the evolution of the solar UV emission in the Mg II band at two different time scales: yearly variations along the solar cycle and transient variations during flare events.
