HEXTE
HEXTE, or High Energy X-ray Timing Experiment, was an instrument aboard NASA's Rossi X-ray Timing Explorer (RXTE). Operational from 1995 to 2012, HEXTE was designed to perform timing and spectroscopy of hard X-rays in the approximate 15 to 250 keV range, complementing the PCA instrument which operated at lower energies.
The instrument consisted of two independent detector clusters, A and B, each built around phoswich scintillation
HEXTE contributed to a wide range of high-energy X-ray studies, including timing analyses of X-ray binaries
After the mission ended in 2012, HEXTE data have remained publicly available through HEASARC, supporting continued
