A Multichannel CCD Spectroheliograph for Studying Nonstationary Phenomena in the Chromosphere of the Sun

Аннотация

A multichannel spectroheliograph (SHG) based on an Alta U16M (4096 × 4096) high-performance cooled CCD camera has been created for studying the active regions and flares on the Sun in the wavelength range of 0.32–1.10 μm with a very low noise level. The SHG is intended for use in the ATB-1 solar tower telescope at the Solar Physics Department of the SAI. This will make it possible to obtain tomographic sections and record the field of plasma-flows rates at different levels in the chromosphere of the Sun.
