CMEx: The Chromospheric Magnetism Explorer

CMEx is a proposed SMEX mission that uses NUV spectropolarimetry to diagnose magnetism from the solar photosphere to the transition region. CMEx explores how the magnetic field evolves from the β ≫ 1 photosphere to the β ≪ 1 corona to form twisted non-potential flux ropes in the corona that are the energy storage devices for magnetic eruptions. This key β transition happens in the chromosphere where NUV spectropolarimetry can give us access to the highly complex dynamics where plasma properties change rapidly.
