Metrology for Measuring Custom Periodicities on Diffraction Gratings
Ningxiao Zhang, Randall McEntaffer, Ross McCurdy +1
We present a new, inexpensive, bench-top method for measuring groove period over large areas with high mapping resolution and high measurement accuracy, dubbed the grating mapper f…
Performance Testing of a Large-Format Reflection Grating Prototype for a Suborbital Rocket Payload
Benjamin D. Donovan, Randall L. McEntaffer, Casey T. DeRoo +8
The soft X-ray grating spectrometer on board the Off-plane Grating Rocket Experiment (OGRE) hopes to achieve the highest resolution soft X-ray spectrum of an astrophysical object w…
Limiting Spectral Resolution of a Reflection Grating Made via Electron-Beam Lithography
Casey T. DeRoo, Jared Termini, Fabien Grise +3
Gratings enable dispersive spectroscopy from the X-ray to the optical, and feature prominently in proposed flagships and SmallSats alike. The exacting performance requirements of t…
Line Spread Functions of Blazed Off-Plane Gratings Operated in the Littrow Mounting
Casey T. DeRoo, Randall L. McEntaffer, Drew M. Miles +13
Future soft X-ray (10 - 50 Angstrom) spectroscopy missions require higher effective areas and resolutions to perform critical science that cannot be done by instruments on current…
Performance Testing of a Novel Off-plane Reflection Grating and Silicon Pore Optic Spectrograph at PANTER
Hannah Marlowe, Randall L. McEntaffer, Ryan Allured +12
An X-ray spectrograph consisting of radially ruled off-plane reflection gratings and silicon pore optics was tested at the Max Planck Institute for extraterrestrial Physics PANTER…
