Abundance Diagnostics from Slitless Imaging Spectrometer: A Proof-of-Concept for MaGIXS-2
Biswajit Mondal, Amy R. Winebarger, P. S. Athiray
Elemental abundance diagnostics in the solar corona are crucial for understanding energy transport, plasma heating, and magnetic activity. Most earlier imaging-spectroscopic studie…
The need for focused, hard X-ray investigations of the Sun
Lindsay Glesener, Albert Y. Shih, Amir Caspi +46
Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a hug…
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),…
Use of a ray-tracing simulation to characterize ghost rays in the FOXSI rocket experiment
J. C. Buitrago-Casas, S. Christe, L. Glesener +12
Imaging X-rays by direct focusing offers greater sensitivity and a higher dynamic range compared to techniques based on indirect imaging. The Focusing Optics X-ray Solar Imager (FO…
Experimental validation of XRF inversion code for Chandrayaan-1
P. S. Athiray, M. Sudhakar, M. K. Tiwari +5
We have developed an algorithm (x2abundance) to derive the lunar surface chemistry from X-ray fluorescence (XRF) data for the Chandrayaan-1 X-ray Spectrometer (C1XS) experiment. Th…
Mapping lunar surface chemistry: new prospects with the Chandrayaan-2 Large Area Soft x-ray Spectrometer (CLASS)
S. Narendranath, P. S. Athiray, P. Sreekumar +4
Surface chemistry of airless bodies in the solar system can be derived from remote x-ray spectral measurements from an orbiting spacecraft. X- rays from planetary surfaces are exci…
Modeling charge transport in Swept Charge Devices for X-ray spectroscopy
P. S. Athiray, S. Narendranath, P. Sreekumar +3
We present the formulation of an analytical model which simulates charge transport in Swept Charge Devices (SCDs) to understand the nature of the spectral redistribution function (…
