The Tipsy single soft photon detector and the Trixy ultrafast tracking detector

We present a new and generic type of detector for photons, electrons and energetic charged particles: a stacked set of curved miniature dynodes in vacuum, created through Micro Electro Mechanical System (MEMS) fabrication techniques on top of a CMOS pixel chip. This combination in itself is an efficient single free electron detector. By capping the system with a traditional photocathode, a highly sensitive timed photon counter can be realized. By capping it with an electron emission membrane `e-brane', a timed MIP tracking detector is realized with a time resolution far superior to current particle detectors. The core innovation, i.e., the stacked curved dynodes on top of a pixel chip, is also relevant for solid-state, atomic and molecular physics experiments.
