We are well
aware of the expediency of creating the new instrument meeting all demands of the near future. Therefore, we fully support the
ideas behind the creation of the
above-mentioned radio telescopes. Considering the realistic financial
conditions in Russia, the ISTP is working on
two versions of SSRT conversion to MVRH which differ by the speed, the methods of frequency
conversion, collection of signals from the antennas, and by the rate of obtaining radio images (in
the modes of frequency scanning and
aperture synthesis). They show that in Russia it is possible to create - with moderate expenses - a multiwave radioheliograph in the
frequency range 2-10 GHz. This instrument cannot compete with FASR as regards the number
of frequencies and spatial
resolution but will provide the necessary data for successful investigations in the field of highly important problems in
solar physics, including the space weather
prediction problem. The difference of the longitudinal location of the SSRT (MWRH in the future) and FASR will make it
possible to carry out mutually complementary
observations of the Sun on a 24-hour basis. The basic expenses incurred by the implementation of the ISTP
project reduce virtually to reequipment of the SSRT by additional instrumentation; the
antenna system, the receiving-recording complex, the automation system, all civil engineering part
and infrastructure of the SSRT complex
will be used in full measure. Alterations may apply to the method and, hence, the system of signal collection.
Substantially smaller expenses will be required for the replacement of the obsolescent CAMAC-modules (by
modern microprocessors), cables, as well
as for the overhaul of the waveguide tunnel (water proofing, protection devices). MWRH will be
accessible to all interested observatories.
