Analytical Fitting of Gamma-ray Photopeaks in Germanium Cross Strip Detectors
Steven E. Boggs, Sean N. Pike
In an ideal germanium detector, fully-absorbed monoenergetic gamma-rays will appear in the measured spectrum as a narrow peak, broadened into a Gaussian of width determined only by…
2021 Effective Area calibration of the Nuclear Spectroscopic Telescope ARray (NuSTAR)
Kristin K. Madsen, Karl Forster, Brian W. Grefenstette +2
We present here the updated calibration of The Nuclear Spectroscopic Telescope ARray NuSTAR, which was performed using data on the Crab accumulated over the last 9 years in orbit.…
NuSTAR low energy effective area correction due to thermal blanket tear
Kristin K. Madsen, Brian W. Grefenstette, Sean Pike +4
A rip in the MLI at the exit aperture of OMA, the NuSTAR optic aligned with detector focal plane module FPMA, has resulted in an increased photon flux through OMA that has manifest…
