SoLEXS --用于日冕研究的低能X射线谱仪
SoLEXS - A low-energy X-ray Spectrometer for Solar Coronal Studies
摘要：
太阳低能X射线光谱仪（SoLEXS）是一种高光谱分辨率（\leq，250 eV，5.9 keV）仪器，具有软X射线能量覆盖范围（\leq，1.5 keV），拟作为Aditya-1号卫星上的额外有效载荷。这背后的动机是为了补充可见发射线空间太阳日冕，这是Aditya-1上的主要有效载荷。SoLEXS数据将补充主要有效载荷的科学目标是：（一）了解直流加热机制，（二）从同一平台研究耀斑与日冕物质抛射的关系，（三）对耀斑现场的温度和排放量进行独立和准确的估计，（四）研究日冕丰度及其在耀斑期间的变化。除了这四个主要科学目标外，该仪器原则上还可以为主有效载荷提供耀斑触发器，并有助于优化机载存储器。
英文摘要：
A Solar Low-energy X-ray Spectrometer (SoLEXS), a high spectral resolution (\leq 250 eV at 5.9 keV) instrument with soft X-ray energy coverage (\leq 1.5 keV), is being proposed as an additional payload on-board Aditya-1. The motivation behind this is to complement the visible emission line space solar coronagraph, the main payload on Aditya-1. The science goals in which SoLEXS data will compliment the main payload are: (i) Understanding of DC heating mechanism, (ii) Studies on the Flare-CME relations from the same platform, (iii) Independent and accurate estimates of temperature and emission measure at the flaring sites, and (iv) Coronal abundance studies and its variations during flares. Apart from these four major science goals, this instrument in principle can provide a flare trigger to the main payload and help in optimizing the on-board memory storage.
