چکیده
Resolve is a payload hosting an x-ray microcalorimeter detector operated at 50 mK in the imaging and spectroscopy mission. It currently under development as part of international collaboration planned to be launched 2023. A primary technical concern microvibration interference sensitive caused by spacecraft bus components. We conducted series verification tests 2021 2022 on ground, results which are reported here. defined interface between instrument. In instrument-level test, flight-model hardware was tested against level injecting it with microvibrations evaluating instrument response using stage temperature stability, adiabatic demagnetization refrigerator magnet current consumption rate, noise spectra. found strong responses when ∼200, 380, 610 Hz. former two cases, beat injected frequency cryocooler harmonics were observed spacecraft-level acceleration measured without suspension entire spacecraft. The reaction wheels (RWs) inertial reference units (IRUs), major sources among components, operated. conclusion, within acceptable levels nominal operational range RWs IRUs. There no evidence that resultant energy resolution degradation beyond allocation budget.

We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar flares. This is part of a trilogy of white papers discussing science, instrument (Bandler et al. 2010), and missions (Bookbinder et al. 2010) to exploit major advances recently made in transition-edge sensor (TES) detect...
