观测太阳日冕结构的动力学对于研究空间天气现象和日冕的全球加热是必要的。热等离子体发射的高温线的轮廓通常通过窄带滤光片积分或通过经典光谱学记录。我们在本文中介绍了一种用于成像光谱的新型便携式仪器(正在建设中)的详细信息:太阳线发射多普勒计(SLED)。它采用多通道减法双通(MSDP)技术,结合了滤光片和窄缝光谱仪的优点,即高时间、空间和光谱分辨率。 SLED 将以高节奏 (1 Hz) 测量 FeX 6374 Å 和 FeXIV 5303 Å 禁线内热日冕环的视线速度(多普勒频移)。它将跟踪太阳活动快速演变事件的动态,例如耀斑或日冕物质抛射(CME),并研究短周期波的日冕加热。观测将在 Lomnický Štít 天文台(LSO,斯洛伐克)或日全食期间使用日冕仪进行。当安装在比亚库夫日冕仪(波兰弗罗茨瓦夫附近)上时,SLED 还将观测 Hα6563 Å 或 He D3 5876 Å 线中日珥的动态。它与各种技术的偏振测量完全兼容。
Observations of the dynamics of solar coronal structures are necessary to investigate space weather phenomena and global heating of the corona. The profiles of high temperature lines emitted by the hot plasma are usually integrated by narrow band filters or recorded by classical spectroscopy. We present in this paper details of a new transportable instrument (under construction) for imaging spectroscopy: the Solar Line Emission Dopplerometer (SLED). It uses the Multi-channel Subtractive Double Pass (MSDP) technique, which combines the advantages of both filters and narrow slit spectrographs, i.e. high temporal, spatial and spectral resolutions. The SLED will measure at high cadence (1 Hz) the line-of-sight velocities (Doppler shifts) of hot coronal loops, in the forbidden lines of FeX 6374 Å and FeXIV 5303 Å. It will follow the dynamics of fast evolving events of solar activity such as flares or Coronal Mass Ejections (CMEs), and also study coronal heating by short period waves. Observations will be performed with the coronagraph at the Lomnický Štít Observatory (LSO, in Slovakia) or during total eclipses. The SLED will also observe the dynamics of solar prominences in Hα6563 Å or He D3 5876 Å lines when mounted on the Białków coronagraph (near Wrocław, Poland). It is fully compatible with polarimetric measurements by various techniques.
