The experiment had the flexibility to tag each event with its pulse height ( proportional to its energy ), and a one or two byte time tag, allowing precision timing of objects such as gamma-ray bursts and pulsars.

The Spectra were taken in two 31-channel pulse height analyzers ( PHAs ), of which the first eight were measured with 1 / 16 s time resolution and the remaining with variable time resolutions depending on the count rate.

Essential elements of such systems include fast detectors for charged particles, discriminators for separating them by energy, counters for counting the pulses produced by individual particles, fast logic circuits ( including coincidence and veto gates ), for identification of particular types of complex particle events, and pulse height analyzers ( PHAs ) for sorting and counting gamma rays or particle interactions by energy, for spectral analysis.

Stassinopoulos micro-miniaturized two prototype space-qualified and pedigreed radiation monitors / dosimeters / spectrometers into a single pill-box sized hybrid instrument, a Pulse Height Analyzer ( PHA ) called the Miniature High-LET Radiation Spectrometer, weighing less than 90 grams, and was awarded a US Patent ( No . 7465926 B2 ) on December 16, 2008 for his " Device system and method for a miniaturized radiation spectrometer . " The instrument has been used for flight measurements on commercial jets, the Concorde, and the DSCOVR satellite which was launched on February 11, 2015.
