A Next Generation Spectrometer: The EUV High-Throughput Spectroscopic Telescope (EUVST)
Abstract
An advanced spectrometer and slit-jaw imaging system has been proposed by an international team to JAXA's competitively selected M-class missions science program. The main scientific goal of the proposed instrument, the EUV High-Throughput Spectroscopic Telescope (EUVST), is to understand the transfer of mass and energy from the solar surface to the solar corona and interplanetary space by observing fundamental processes occurring in the solar atmosphere. The mission has two specific scientific objectives: (I) to understand how fundamental processes lead to the formation of the solar atmosphere and the solar wind, and (II) to understand how the solar atmosphere becomes unstable, releasing the energy that drives solar flares and eruptions. EUVST will make major advances by combining a seamless temperature coverage of the solar photosphere, chromosphere, transition region, and corona with very high spatial resolution (0.4ʺ or 300km) and unprecedented cadence (as high as 0.1s). This instrument will complement new solar observatories such as DKIST, the Parker Solar Probe, and Solar Orbiter that will be operational during the proposed mission.
