Description
The EUVST spectrograph (EUV High-throughput Spectroscopic Telescope) onboard the upcoming SOLAR-C spacecraft (JAXA), scheduled for launch in the late 2020s, will simultaneously observe a wide temperature range: from the 10,000-Kelvin chromosphere to the million-Kelvin corona, and even to 10 million-Kelvin solar flares, allowing the continuous tracking of plasma and energy transport. The spectrograph consists of three long wavelength (LW) CMOS cameras (NASA/NRL) and one short wavelength (SW) CCD camera (ESA/UCL-MSSL) and will act as a successor to Hinode/EIS.
In this work, we use simulations from multidimensional MHD code MURaM and an accurate camera response model to analyse the expected performance of the SW camera. We use our framework to perform a Monte Carlo study and calculate the expected spatial and spectral resolution of the SW detector, along with the expected accuracy in Doppler velocity and excess broadening (non-thermal velocity) for the pre-flare atmosphere modelled by Cheung et al. (2019). We compare these results to recent studies of pre-flare non-thermal velocity with Hinode/EIS.
