TetraCal: A 4D Calorimeter Prototype for Next Generation High Energy Detectors

TetraCal is a concept for a calorimeter capable of withstanding high radiation damage (compatible to FCC-ee) while at the same time featuring high spatial and time granularity. The detector is based on scintillation, wavelength-shifting technologies and photosensors including SiPM or LGADs. The concept is born as a spin off from the RADiCAL Detector concept which successfully proved to be able to resolvethe to 12ps timing resolution with a Moliere radius of 1 cm. In this talk, the detector performance to an electron beam from 20 to 150 GeV/c will be presented.
