Abstract
Arcus Probe, an X-ray and UV spectroscopy mission proposed for the 2023 NASA Astrophysics Probe call, uses two co-aligned spectrometers—the X-ray spectrometer (XRS) and the UV spectrograph (UVS). We discuss the process of aligning the XRS and UVS such that they acquire simultaneous spectra of astrophysical sources during the observatory’s operation. The definition of each instrument’s field of view and line of sight is given, informing the alignment strategy of the XRS to the UVS. Comprehensive error budgets, beginning with the internal alignment of the XRS optics and proceeding through on-orbit commissioning, are detailed. The mechanism for achieving such alignment on orbit exceeds the required alignment tolerances by ≥14x in all six degrees of freedom, lending confidence that the alignment required for successful science operations can be achieved.
