Accelerator-on-a-chip advance steers and accelerates electrons at the microchip scale

https://phys.org/news/2024-02-chip-advance-electrons-microchip-scale.html

"cheaper, smaller (microns, not miles) particle accelerator... steer (accelerating, defocusing, focusing) electrons for almost a mm, gaining 23.7 kilo-electron-volts, in silicon vacuum with sub-micron channel, illuminated with shaped laser pulse... future: 3d rather than 2D for greater energy... low-energy electrons given initial kick, fed into Broaddus' device, then fed to glass accelerator withstanding even greater pummeling by lasers than silicon, toward light-speed... high-energy physics, industry, medicine"
