Multiplier Cathode Arrangements TRIZ Cases
- GEM Board Photomultiplier for High-Temperature Vibration Environments
A rugged GEM board photomultiplier uses titanium, ceramic, and atmospheric-pressure operation to withstand heat and vibration.
- Meta-Surface Photoelectric Conversion for Polarization Detection
Intersecting antenna and bias portions convert polarization components into electron emission, simplifying electromagnetic wave detection.
- Alkali-Coated Metasurface Electron Emitter for Charge-Up Suppression
An alkali metal layer lowers work function and suppresses charge-up, helping metasurface electron emitters achieve higher sensitivity.
- Borderless Overlay Display Layout for Compact Night Vision
Integrating data-handling circuitry inside the active display area removes opaque borders and beam splitters, cutting night vision bulk and weight.
- Photomultiplier Tube Oxide Barrier for High-Temperature Sensitivity
A trivalent metal oxide barrier blocks alkali migration and gas permeation, preserving photomultiplier sensitivity and limiting after-pulses at high temperature.
- Borderless Overlay Display Layout for Low-SWaP Night Vision
Placing display circuitry within the active area removes opaque borders, shrinking night vision overlays and avoiding bulky beam splitters.
- Microchannel Plate Backscatter Layer for First Strike Efficiency
An electron backscatter layer redirects primary electrons onto a booster layer, raising MCP first strike efficiency and low-light SNR.
- Photocathode Capacitive Interface for Higher Quantum Yield
A biased transparent conductive and dielectric interface pulls photoelectrons from the recombination zone to raise photocathode quantum yield.
- Meta-Surface Photoelectric Conversion for Multi-Wavelength Gas Detection
Multiple meta-surface conversion units with different patterns broaden detectable wavelengths, enabling simultaneous gas component detection.
- Pt Resistance Layer Structure for Wide-Temperature Electron Multipliers
A Pt particle resistance layer stabilizes MCP resistance and current across -60°C to +60°C, extending electron multiplier operation.
- Semi-Transparent Photocathode Assembly With Bimetal Sapphire Sealing
A bimetal coupling matched to sapphire limits thermal stress, keeps vacuum tightness, and supports high-temperature GaN photocathode activation.
- Electron Tube Photocathode Mounting for Stable Voltage Contact
Elastic biasing portions hold the photocathode plate in stable electrical contact despite assembly tolerances and thermal deformation.
- Reflective Photocathode Array PMT Design for Quantum Efficiency
A reflective photocathode array generates photoelectrons directed toward nested dynode structures within a compact photomultiplier tube housing.
- Electron Tube Module Prism Alignment and Quantum Efficiency
Bonding a prism parallel to the casing wall simplifies electron tube alignment while reflecting light back to the photocathode to increase quantum efficiency.
