高分辨软X射线光谱学和太阳活动区热（5-10 MK）等离子体的探索
High resolution soft X-ray spectroscopy and the quest for the hot (5-10 MK) plasma in solar active regions
摘要：
我们讨论了诊断可用于研究5-10 MK等离子体在太阳日冕，这是关键，了解太阳活动区的核心加热。我们提出了几个模拟光谱，并表明，良好的诊断是可在软X射线，约100埃，作为六个电离阶段的铁可以同时观察到，和电子密度的推导，在一个狭窄的光谱区域。由于这一光谱范围几乎是未开发的，我们提出了一个可用的和模拟的光谱分析，比较热发射与冷却组件。我们采用最近设计的多层提出的估计计数率的热线，与基线光谱仪设计。优秀的计数率被发现，开辟了令人兴奋的机会，以获得高分辨率的光谱热等离子体。
英文摘要：
We discuss the diagnostics available to study the 5-10 MK plasma in the solar corona, which is key to understanding the heating in the cores of solar active regions. We present several simulated spectra, and show that excellent diagnostics are available in the soft X-rays, around 100 Angstroms, as six ionisation stages of Fe can simultaneously be observed, and electron densities derived, within a narrow spectral region. As this spectral range is almost unexplored, we present an analysis of available and simulated spectra, to compare the hot emission with the cooler component. We adopt recently designed multilayers to present estimates of count rates in the hot lines, with a baseline spectrometer design. Excellent count rates are found, opening up the exciting opportunity to obtain high-resolution spectroscopy of hot plasma.
