FPGA Fault Tolerance in Particle Physics Experiments — •Jano Gebelein, Heiko Engel, and Udo Kebschull — Kirchhoff-Institute for Physics, Heidelberg University

The behavior of matter in physically extreme conditions is in focus of many high-energy-physics experiments. For this purpose, high energy charged particles (ions) are collided with each other and energy- or baryon densities are created similar to those at the beginning of the universe or to those which can be found in the center of neutron stars. In both cases a plasma of quarks and gluons (QGP) is present, which immediately decomposes to hadrons within a short period of time. At this process, particles are formed, which allow statements about the beginning of the universe when captured by large detectors, but which also lead to the massive occurance of hardware failures within the detector's electronic devices. This contribution is about methods to mitigate radiation susceptibility for Field Programmable Gate Arrays (FPGA), enabling them to be used within particle detector systems to directly gain valid data in the readout chain or to be used as detector-control-system.
