Research Interests

Eric Eisenhandler is Emeritus Professorial Research Fellow in the Particle Physics Research Centre, having retired in September 2009. He worked on the ATLAS Experiment at the CERN Large Hadron Collider, in Geneva, from the early 1990s. Earlier, he worked on the H1 Experiment on the HERA Collider at DESY, in Hamburg, and on the UA1 Experiment at CERN that discovered the W and Z intermediate vector bosons unifying the electromagnetic and weak forces of nature.

Eric's main interests have focused on instrumentation for particle physics experiments, and he has worked for many years on calorimeters and most importantly on trigger systems. His current speciality is fast, massively parallel, programmable custom electronics for the first-level triggers that typically must reject well over 99% of the potential event data within microseconds of the particle collisions whilst retaining with high efficiency all the rare and exciting physics events that might occur only every few hours or days. For 10 years he was international Project Leader and UK Project Manager of the ATLAS Level-1 Calorimeter Trigger project.

Earlier work on H1 included the Time-of-Flight System used to reject backgrounds, the Forward Muon Trigger, and leadership of the timing electronics project for the Spacal (calorimeter for the backwards region).

On UA1 he did much of the development work for the Hadron Calorimeter, was deeply involved in the first-generation Calorimeter Trigger, and led the project to build a Calorimeter Trigger for the upgrade.


His recent teaching included six years as Course Organiser for Scientific Measurement, the first-year laboratory course. Currently he guest lectures on home energy conservation and microgeneration in Physics of Energy and the Environment.
