From 17th-19th February 2026, the 21st “Trento” Workshop on Advanced Silicon Radiation Detectors will take place in Perugia, Italy. The CiS research institute will be represented with a contribution on improving the sensitivity of Low Gain Avalanche Detectors (LGADs) to low-energy electrons. Building on pathbreaking work by Pellegrino et al. [1], LGADs at CiS Forschungsinstitut have been further developed to achieve quantum efficiencies of up to 450% for electrons with an energy of 1 keV. Conventional detectors exhibit no sensitivity to electrons at this energy. The key factors were minimizing the thickness of the entrance window and positioning the amplification region close to the surface. Dr. Kevin Lauer will present these research findings on Wednesday, 18th February 2026, as part of the session LGAD.
The aim is to bring together experts on sensor technology (design, simulation and processing), front-end electronics, system issues, detector applications (e.g., particle tracking, medical and biological imaging), etc. for discussions of the present state of the art, establishment of requirements of the fields and future programs.
The research and development work described was funded by the German Federal Ministry for Economic Affairs and Climate Protection (BMWE) as part of the research project “Low Gain Avalanche Detectors for 1keV Electrons” (eLGAD).
