Abstract:
A proposal of a new telescope/auxiliary instrumentation system for the solar
coronal station at Lomnicky Stit (2632 m asl) is described in both the general
concept and some particular technical details. The main aim of the system is
to observe the near-limb photospheric and chromospheric layers of the solar
atmosphere by the white-light and narrow-band imaging, as well as to perform
the visible and near-infrared spectroscopy and spectropolarimetry of the parts
of solar disk already mentioned. These sorts of data, measured simultaneously
with the coronal emission line profiles which are regularly obtained at this
time by coronagraph, could give us a great amount of physical information
about the solar activity events (such as the height distribution of energy,
mass, magnetic fields and their time evolution). The initial ideas and
motivation of the project are explained. The parameters of the system
components - refractors, narrow band filters, focal plane detectors and fibre
optics positioners, telescope-spectrograph coupling via fiber optics,
spectrographs, detectors and computers for the control of observations and the
data acquisition - are discussed. TV CCD detectors connected with the advanced
frame grabbers and the IBM PC computers are especially taken into account for
the data acquisition. We also briefly mention advantages and disadvantages of
the system as a whole. Finally, the future prospects of the project proposal
are briefly described.
