Cathode Ray Tubes/Electron Beam Tubes TRIZ Cases

Conical waveguides concentrate light-induced electric fields to emit electrons across a gap, collecting broad-spectrum solar energy without semiconductors.

An expanded metal extraction grid with a clamped curved holder limits thermal deformation, keeping plasma beams uniform over long operation.

Time-varying acceleration shapes ultracold-atom electron bunches to boost coherent X-ray and EUV brilliance for higher-resolution metrology.

Step-graded and overshoot buffer layers on GaAs cut defects and extend InGaAs photocathode sensitivity beyond the 900 nm limit.

Step-graded and overshoot layers on GaAs enable InGaAs photocathodes to reach 1064-1200 nm with fewer defects and higher quantum efficiency.

A multilayer, patterned cathode structure improves emission uniformity, suppresses hot spots, and reduces screening for higher current density.

An off-axis ion beam is chromatically dispersed and aperture-filtered to tune energy spread and beam current while reducing workpiece damage.

Chromatic dispersion and aperture filtering let a focused ion beam deliver selectable current and energy spread while limiting Coulomb-driven spot growth.

A spacer-fixed photocathode and lens assembly removes in-gun distance adjustment, simplifying electron gun installation and reducing size.

Inductive coupling replaces melting electrodes in a compact plasma chamber, boosting EUV brightness while improving source stability and lifetime.

Partially transmissive UV windows and aligned sensing elements improve flame detection while blocking ambient light and lowering assembly cost.

Selective metal deposition on one side of MCP channel openings boosts first-strike efficiency, OAR, and SNR without weakening the plate.

An electrodeless plasma chamber uses inductive coupling and insulated grounding to cut debris, limit ion attraction, and keep backside optical access.

Series FETs with current feedback hold load current constant at high voltage, helping field emission electron sources respond quickly and stay stable.

A thermal barrier between the cathode carrier and holder cuts heat loss, limits contamination, and stabilizes electron beam quality.

A reduced carrier-holder contact area creates a thermal barrier that cuts heat loss, lowers energy use, and improves electron beam quality.

A correction detector measures beam-to-beam electron crosstalk so brightness signals can be corrected and ghost images reduced.

Selective one-sided metallization of tapered MCP channel openings cuts electron scattering while raising open area ratio, gain, and SNR.

High-reduction cold rolling and short recrystallization annealing cut directional property variation in Fe-Ni thin plates for accurate cutting.

Segmented transparent display zones balance power draw, light transmission, and image quality in night vision and heads-up viewing.

A hydrogenated liquid metal emitter stabilizes the electron surface at high temperature, extending gun life while keeping beam output uniform.

Segmenting the coil chamber via a vacuum barrier prevents heat-induced deformations that compromise dimensional precision in multipole elements.

Calcining silicon nitride reactants below 1550°C yields fine-grained precursors, eliminating extensive grinding and contamination risks.
