Atomic Beams Shoot Straighter via Cascading Silicon Peashooters | Research Horizons

Atomic beams conjure fantasies of gigantic Space Force cannons. But tiny atomic beams now shoot out of newly engineered collimators, a kind of particle peashooter, that could land in handheld devices. The beams create precise inertia better than a gyroscope's that could help spacecraft navigate. The atomic beams from the new silicon collimators could also let physicist cheaply and easily produce exotic quantum states for study. Electronics and Nanotechnology
