Proceedings ArticleDOI
Time - resolved Gamma Ray spectral analysis of planetary neutron and Gamma Ray instrumentation
J. Bodnarik,Dan Burger,Arnold Burger,L. G. Evans,S. R. Floyd,Lucy F. Lim,T. McClanahan,M. Namkung,Suzanne F. Nowicki,A. M. Parsons,Jeffrey Schweitzer,R. Starr,Keivan G. Stassun,Jacob I. Trombka +13 more
TL;DR: In this paper, the authors presented the results of their experimental data using the time tagged event-by-event data analysis technique compared with non-time-gated data taken at the test facility at NASA Goddard Space Flight Center.
Journal ArticleDOI
Neutron-induced gamma-ray measurements on soft landers
TL;DR: A recent advance is the combination of a gamma-ray spectrometer with a compact, pulsed neutron generator, which increases the neutron flux by orders of magnitude as mentioned in this paper, allowing elemental compositions to be inferred to determine different mineral compositions and to characterize the nature of the area studied.
Journal ArticleDOI
Spectral analysis and compositing techniques for the Near Earth Asteroid Rendezvous (NEAR Shoemaker), X-ray and Gamma-Ray Spectrometers (XGRS)
T. P. McClanahan,Jacob I. Trombka,Larry R. Nittler,William V. Boynton,J. Brückner,S. W. Squyres,Larry G. Evans,J. S. Bhangoo,Pamela Elizabeth Clark,S. R. Floyd,E. McCartney,I. Mikheeva,R. D. Starr +12 more
TL;DR: An X-ray and Gamma-Ray Spectrometer (XGRS) is on board the Near Earth Asteroid Rendezvous (NEAR) spacecraft to determine the elemental composition of the surface of the asteroid 433 Eros as mentioned in this paper.
A unique outside neutron and gamma ray instrumentation development test
L. Evans,S. R. Floyd,T. McClanahan,M. Namkung,A. M. Parsons,J. Schweitzer,R. Starr,J. Trombka +7 more
TL;DR: An outside neutron and gamma ray instrumentation test facility has been constructed at NASA's Goddard Space Flight Center (GSFC) to evaluate conceptual designs of gamma ray and neutron systems that are intended for future planetary lander and rover missions as mentioned in this paper.
