Summary

DescriptionMars Observer - GRS.png	English: When a gamma ray interacts with the detector, hole-electron pairs are created that are quickly swept to the appropriate electrodes. This small charge is collected by a sensitive preamplifier, which produces a pulse whose height (voltage) is proportional to the energy deposited in the crystal. This pulse is then shaped and amplified and passed to a pulse-height analyzer, which counts the events in the form of a histogram sorted according to energy.
