Abstract

Presented herein are systems, methods, and nonvolatile computer-readable storage devices for informing a particle event processor of a particle detector of events arising within a sensor period. The systems, methods, and nonvolatile computer-readable storage devices involve the generation of a sensor data set detected by a particle event sensor and representing the events arising within the particle detector during the sensor period. The systems, methods, and nonvolatile computer-readable storage devices also involve the compression of the sensor data set with a waveform compression technique to generate a compressed sensor data set, and the transmission of the compressed sensor data set to the particle event processor.
