ABSTRACT
All particle scattering experiments, both fixed target and collider types, require particle detectors to find and possibly identify all the particles emerging from a scattering event. The electronics associated with particle detectors can be separated into two groups: on-detector electronics that are mounted in close proximity to the sensors and off-detector electronics located many meters, perhaps a few hundred meters, away from the sensors. The picture of the ATLAS detector demonstrates one of the design requirements for the electronics for collider physics experiments, reliability. Power dissipation of the electronics is a serious constraint. As the size of collider detectors has increased with increasing channel count and the beam intensities have increased, the resulting rates of data needed to be transmitted out of the detectors have also increased. The colliders are typically designed to operate for at least 10 years with only minor repairs.
