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 Mechanical Electronic Systems (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 MTP 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.
