Abstract
There is a growing interest in the science uniquely enabled by observations in the MeV range, particularly in
light of multi-messenger astrophysics. The Compton Pair (ComPair) telescope, a prototype of the AMEGO
Probe-class concept, consists of four subsystems that together detect and characterize gamma rays in the MeV
regime. A double-sided strip silicon Tracker gives a precise measure of the first Compton scatter interaction
and tracks pair-conversion products. A novel cadmium zinc telluride (CZT) detector with excellent position
and energy resolution beneath the Tracker detects the Compton-scattered photons. A thick cesium iodide (CsI)
calorimeter contains the high-energy Compton and pair events. The instrument is surrounded by a plastic anticoincidence (ACD) detector to veto the cosmic-ray background. In this work, we will give an overview of the
science motivation and a description of the prototype development and performance.
