利用马歇尔掠入射X射线光谱仪（MaGIXS）从高温辐射诊断太阳活动区加热
Solar Active Region Heating Diagnostics from High Temperature Emission using the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
摘要：
高温等离子体的相对量已被发现是一个有用的诊断，以确定次分辨率结构上的日冕加热的频率。当回路不经常加热时，预计在更宽的温度范围内进行广泛的排放测量（EM）。对于环路更接近平衡的高频加热，预期EM更窄。软X射线光谱包含许多提供高温诊断的谱线，包括来自Fe XVII-XIX的谱线。2020年，马歇尔掠入射光谱仪（MaGIXS）将对这一太阳光谱区域进行观测。在本文中，我们得出预期的谱线强度在MaGIXS不同量的高温等离子体，以证明一个简单的线比，这些提供了一个强大的诊断，以确定加热频率。同样，我们检查AIA通道强度的比率，从XRT的过滤器比率，和从FOXSI探空火箭的能量带，以确定它们对这个参数的敏感性。我们发现，FOXSI和MaGIXS提供了良好的诊断能力的高温等离子体。然后，我们将预测的线比率与数值模型的输出进行比较，并确认MaGIXS比率为加热频率提供了极好的诊断。
英文摘要：
The relative amount of high temperature plasma has been found to be a useful diagnostic to determine the frequency of coronal heating on sub-resolution structures. When the loops are infrequently heated, a broad emission measure (EM) over a wider range of temperatures is expected. A narrower EM is expected for high frequency heating where the loops are closer to equilibrium. The soft X-ray spectrum contains many spectral lines that provide high temperature diagnostics, including lines from Fe XVII-XIX. This region of the solar spectrum will be observed by the Marshall Grazing Incidence Spectrometer (MaGIXS) in 2020. In this paper, we derive the expected spectral lines intensity in MaGIXS to varying amounts of high temperature plasma to demonstrate that a simple line ratio of these provides a powerful diagnostic to determine the heating frequency. Similarly, we examine ratios of AIA channel intensities, filter ratios from a XRT, and energy bands from the FOXSI sounding rocket to determine their sensitivity to this parameter. We find that both FOXSI and MaGIXS provide good diagnostic capability for high-temperature plasma. We then compare the predicted line ratios to the output of a numerical model and confirm the MaGIXS ratios provide an excellent diagnostic for heating frequency.
