A wide range of applications require the measurement of event times to nanosecond or picosecond resolution The event may be the arrival time of an electronic pulse, or the time at which a photon or charged particle strikes a detector.

Overview
Features & Benefits
The positron is the antiparticle of the electron
A positron collision with an electron results in the annihilation of both particles and the emission of two characteristic 511-keV gamma rays
This phenomenon is useful to test predictions of quantum theory with regardto the differences between electron and positron interactions with matter
In addition, the positron has proven to be a useful tool in the study of various structures and processes
The lifetime of the positron is a measure of the local electron density at the point of annihilation
The annihilation can be easily detected by virtue of the gamma rays emitted
