## Abstract

A particle accelerator random number generator system comprises a particle accelerator, a particle event detector, and a processing application. Operation steps include initiating the particle accelerator; detecting a particle event by the particle event detector; recording a binary event from the detected particle event; determining if sufficient binary events have been recorded for the desired random number strength; if not, return to the step of detecting a particle event; if so, converting the random number binary string to a random number generated hexadecimal; applying the random number generated hexadecimal string for an encryption key; and using the random number hexadecimal key to encrypt an application.
