Future instrumentation for solar physics: a double channel MOF imager on board ASI space mission ADAHELI

A Magneto-Optical Filter-based system has been proposed as an optional payload for ASI’s low-budget Solar Mission ADAHELI, which has completed its Phase A feasi- bility study.

Description
Summary:A Magneto-Optical Filter-based system has been proposed as an optional payload for ASI’s low-budget Solar Mission ADAHELI, which has completed its Phase A feasi- bility study. The instrument is capable of providing simulta- neous Dopplergrams, intensity and magnetic solar full-disk maps using the potassium 770 nm and sodium 589 nm solar Fraunhofer lines. The instrument is a version, re-designed for a space environment, of the one which has run an observ- ing campaign at the South Pole in 2008 with unprecedented performance. The MOF-based system we present here is a low-cost, low-weight instrument, thus particularly fit to space applications, capable of providing stability and sensi- tivity of signals on long-term observations. The instrument will explore regions of the oscillation spectrum not available to other missions’ instruments.
