Abstract

HEX-P is a probe-class mission concept that will combine high angular resolution (⪅15 arcsec) x-ray imaging with broad band spectral coverage (0.2-80 keV) to enable revolutionary new insights into important astrophysical questions identified by the 2020 Decadal Survey. The bandpass is achieved with a 20-meter focal length provided by an extendable boom from Northrop Grumman, Deployables, and a metrology system is required to measure the bench-to-bench deflections and reconstruct the point spread function. We describe the metrology system derived from NuSTAR, which is a laser metrology system monitoring the motion, normal to the optical axis, of the bench carrying the optics relative to the focal plane with a resolution better than 50 micrometers. We also describe the boom and show that the metrology system is well matched to the predicted behavior of the boom and capable of meeting the angular requirement.
