Antimatter knows when the chips are down

By Ian Sample A MICROSCOPE that fires pulses of antimatter can pick up defects that no other microscope can detect, say the German scientists who designed it. Antimatter microscopes could be invaluable to people who make silicon chips. Werner Triftshäuser at Munich’s Military University used a radioactive isotope of sodium that produces positrons—anti-electrons—as it decays. The positrons pass through a series of electric fields that bunch them into pulses before they strike the target on the microscope stage. When positrons collide with a material, they recombine with electrons,
