Abstract

The Compact Doppler Magnetograph (CDM) is a space-qualified, miniaturized Doppler magnetograph, tailored to the requirements of a solar polar mission, and designed to provide photospheric line-of-sight magnetic field and Doppler velocity measurements of the solar surface. CDM is derived from the proven GONG (Global Oscillations Network Group) instrument design (Harvey et al., 1988, 1996), with a space qualified prototype developed for the Solaris solar polar MIDEX mission (Hassler et al., 2020). CDM has roughly 1/3 the mass of current state-of-the-art Doppler magnetographs (e.g., SOHO/MDI, SDO/HMI, SolO/PHI), with greatly increased sensitivity to the magnetic field (B) and Doppler velocity (v) and the capability to perform over an expanded spacecraft orbital velocity range, which is required to fit within the mission design constraints of currently feasible high latitude solar polar missions.
