ARTEMIS- IV太阳射电光谱仪十年
Ten Years of the Solar Radiospectrograph ARTEMIS-IV
摘要：
雅典大学的太阳射电光谱仪（ARTEMIS-IV）自1996年以来一直在塞莫皮莱卫星通信站运行。观测范围从日冕底部（650 MHz）到约2个太阳半径（20 MHz），时间分辨率为1/10-1/100秒。该仪器记录，是在动态光谱的形式，测量无线电通量作为高度的函数在日冕中，我们的意见相结合的空间数据从Nancay Radioheliograph每当需要的3D位置信息出现。ARTEMIS-IV在研究太阳射电爆发方面的贡献有两个方面：第一，在研究新的光谱特征方面，因为其高采样率有助于研究射电事件中的精细结构。另一方面，由于其扩展的频率范围与风/波接收器的范围互补，而且可以很容易地将观测结果结合起来，因此它被用于研究太阳爆发与行星际现象之间的联系。本报告简要介绍了这一行动。设想今后将与立体声/波和LOFAR低频接收器进行联合观测。
英文摘要：
The Solar Radiospectrograph of the University of Athens (ARTEMIS-IV) is in operation at the Thermopylae Satellite Communication Station since 1996. The observations extend from the base of the Solar Corona (650 MHz) to about 2 Solar Radii (20 MHz) with time resolution 1/10-1/100 sec. The instruments recordings, being in the form of dynamic spectra, measure radio flux as a function of height in the corona; our observations are combined with spatial data from the Nancay Radioheliograph whenever the need for 3D positional information arises. The ARTEMIS-IV contribution in the study of solar radio bursts is two fold- Firstly, in investigating new spectral characteristics since its high sampling rate facilitates the study of fine structures in radio events. On the other hand it is used in studying the association of solar bursts with interplanetary phenomena because of its extended frequency range which is, furthermore, complementary to the range of the WIND/WAVES receivers and the observations may be readily combined. This reports serves as a brief account of this operation. Joint observations with STEREO/WAVES and LOFAR low frequency receivers are envisaged in the future.
