Arcus, a free-flying spacecraft featuring a high resolution X-ray spectrometer, was a Medium-class Explorer concept proposed to NASA in a recent (2016) Explorer announcement of opportunity. Arcus utilizes advancements in X-ray transmission grating technology (Critical-Angle Transmission, or CAT gratings) and cost-effective silicon pore optics (SPO), enabling it to take soft X-ray (300 - 2000 eV) spectra of astronomical point sources with unprecedented sensitivity and resolution.
