Concept of a Double Tilted Rowland Spectrograph for X-rays
Hans Moritz Günther, Casey T. DeRoo, Ralf K. Heilmann +1
High-resolution spectroscopy in soft X-rays ( keV) requires diffractive elements to resolve any astrophysically relevant diagnostics, such as closely spaced lines, weak absorpt…
Transmission grating arrays for the X-ray spectrometer on Arcus Probe
Ralf K. Heilmann, Alexander R. Bruccoleri, James A. Gregory +6
The Arcus Probe mission concept has been submitted as an Astrophysics Probe Explorer candidate. It features two co-aligned high-resolution grating spectrometers: one for the soft x…
The First Flight of the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
Sabrina L. Savage, Amy R. Winebarger, Ken Kobayashi +34
The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) sounding rocket experiment launched on July 30, 2021 from the White Sands Missile Range in New Mexico. MaGIXS is a unique…
X-ray performance of critical-angle transmission grating prototypes for the Arcus mission
Ralf K. Heilmann, Alexander R. Bruccoleri, Vadim Burwitz +12
Arcus is a proposed soft x-ray grating spectrometer Explorer. It aims to explore cosmic feedback by mapping hot gases within and between galaxies and galaxy clusters and characteri…
Calibration of the MaGIXS experiment II: Flight Instrument Calibration
P. S. Athiray, Amy R. Winebarger, Patrick Champey +21
The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) is a sounding rocket experiment that observes the soft X-ray spectrum of the Sun from 6.0 - 24 Angstrom (0.5 - 2.0 keV),…
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…
The Interface Region Imaging Spectrograph (IRIS)
B. De Pontieu, A. M. Title, J. Lemen +85
The Interface Region Imaging Spectrograph (IRIS) small explorer spacecraft provides simultaneous spectra and images of the photosphere, chromosphere, transition region, and corona…
MMT & Magellan Infrared Spectrograph
Brian McLeod, Daniel Fabricant, George Nystrom +19
The MMT and Magellan infrared spectrograph (MMIRS) is a cryogenic multiple slit spectrograph operating in the wavelength range 0.9-2.4 micron. MMIRS' refractive optics offer a 6.9…
Hectospec, the MMT's 300 Optical Fiber-Fed Spectrograph
Daniel Fabricant, Robert Fata, John Roll +6
The Hectospec is a 300 optical fiber fed spectrograph commissioned at the MMT in the spring of 2004. A pair of high-speed six-axis robots move the 300 fiber buttons between observi…
