A rugged GEM board photomultiplier uses titanium, ceramic, and atmospheric-pressure operation to withstand heat and vibration.
Intersecting antenna and bias portions convert polarization components into electron emission, simplifying electromagnetic wave detection.
An alkali metal layer lowers work function and suppresses charge-up, helping metasurface electron emitters achieve higher sensitivity.
Integrating data-handling circuitry inside the active display area removes opaque borders and beam splitters, cutting night vision bulk and weight.
A trivalent metal oxide barrier blocks alkali migration and gas permeation, preserving photomultiplier sensitivity and limiting after-pulses at high temperature.
Placing display circuitry within the active area removes opaque borders, shrinking night vision overlays and avoiding bulky beam splitters.
An electron backscatter layer redirects primary electrons onto a booster layer, raising MCP first strike efficiency and low-light SNR.
