Chinese Giant Solar Telescope (CGST) is the next generation ground-based solar telescope which was formally listed into the National Plans of Major Science and Technology Infrastructures. We have got series progresses of CGST in the recent years, from site testing to detailed designs. CGST is currently designed to be an 8m Ring Solar Telescope (RST). As an 8-meter solar telescope, the designing of CGST still faces some serious problems, although the ring structure is propitious to the thermo controlling and the high precision magnetic field measuring. The active control and the optical system of CGST are introduced. Then, simulations and the key calculations of the telescope, including the polarization analysis and the thermo calculation result are displayed. The present site testing methods and some results are introduced too. Finally, as the comparison in science and technology, the Chinese space solar telescope plans, such as the Deep Space Solar Observatory (DSO) and its progress are simply introduced.
SMESE (SMall Explorer For the study of Solar Eruptions) is a Franco-Chinese microsatellite mission. The scientific
objectives of SMESE are the study of coronal mass ejections and flares. Its payload consists of three instrument
packages : LYOT, DESIR and HEBS. LYOT is composed of a Lyman α (121.6 nm) coronagraph, a Lyman α disk imager and a far UV disk imager. DESIR is an infrared telescope working at 35 μm and 150 μm. HEBS is
a high energy burst spectrometer working in X rays and γ rays covering the 10 keV to 600 MeV range. SMESE
will be launched around 2011, providing a unique opportunity of detecting and understanding eruptions at the
maximum activity phase of the solar cycle in a wide range of energies. The instrumentation on board SMESE is
described in this paper.
Solar activity is one of the main sources of space disturbances, which are primarily responsible for space disaster weather. Solar activity is concerned with 11 years period and has many exhibitions such as the change of sunspot's number and solar radio flux in 10.7cm wavelength. The 1.0-2.0 GHz, 2.6-3.8 GHz, and 5.2-7.6 GHz solar radio spectrometers and 2840 MHz solar radio telescope of National Astronomical Observatory in Huairou Solar Observational Station have got considerable radio flux data since 1999. In order to make further researches on solar action and develop space weather forecast, the real-time observed data should be well utilized. Therefore we designed the data acquisition, antenna control and real-time web-based database system for the 2840 MHz solar radio telescope. The paper introduces the whole design of a PCI-based data acquisition, antenna control and real-time web-based database system for the solar radio observation at HuaiRou in China. The popular PCI controller-PCI9052 is utilized to implement the interface between PCI bus and peripheral devices. PLD chip is applied for the data transferring and antenna control. The device driver of Windows is developed based on Driverworks and Windows DDK. The real-time database is based on MySQL and Apache.
