Abstract
Arcus is a concept for a probe class mission to deliver high-resolution FUV and x-ray spectroscopy. For x-rays, it combines cost-effective Silicon Pore Optics (SPO) with high-throughput Critical-Angle Transmission (CAT) gratings to achieve R 3000 in a bandpass from 12-50 Å. We show in detail how the x-ray and the UV spectrographs (XRS and UVS) on Arcus will be aligned to each other. For XRS we present ray-tracing studies to derive performance characteristics such as the spectral resolving power and effective area, study the effect of misalignments on the performance, and conclude that most tolerances can be achieved with mechanical means alone. We also present an estimate of the expected on-orbit background.
