Prof. Aharon Levy participates in three international collaborations, FCAL, CLICdp and ILD, all three connected with detector R&D for future linear electron-positron colliders. In particular, his group develops a prototype electromagnetic calorimeter for measuring the luminosity, a physical entity necessary for any collider to turn measured events into cross sections.
Research achievements: succeeded to build ultra-thin (~700 microns) silicon sensor planes which allows to build a compact calorimeter. The width of the electromagnetic shower (Moliere radius) was reduced by more than a factor of two from the existing older version.
Future directions: double the size of the existing calorimeter prototype by the end of 2019. In the more-distant future, join the study and development of the LUXE experiment at the European XFEL in Hamburg whose aim is to reach the Schwinger limit predicted in non-perturbative QED in the presence of a high electromagnetic field.
