Orbital soft protons can severely degrade the performance of astronomical X-ray observatories. On the one hand, they may cause permanent radiation damage to X-ray detectors; on the other hand, they introduce an irreducible background component. Our low-energy grazing-incidence scattering setup provides experimental data for the validation of radiation transport simulations used in the assessment of future X-ray missions. Recent measurements indicate that a significant fraction of protons scattered from X-ray optics undergo charge exchange and therefore cannot be mitigated by magnetic diverters. In addition, we present initial proton-transmission measurements through a thin X-ray filter and compare them qualitatively with TRIM simulations. Quantitative measurements of energy loss and charge-exchange fractions, together with comparisons with TRIM and Geant4, are planned. In this publication, we present the upgraded experimental setup together with commissioning measurements for grazing-incidence scattering and proton transmission through thin X-ray filters.
