University of Michigan Researchers Create Tabletop Antimatter “Gun”
At the University of Michigan, an international team of physicists has begun experimenting with its tabletop-sized super laser, modding it into an antimatter “gun.”
…Up until now, machines capable of creating positrons — coupled with electrons, they comprise the energy similar to what’s emitted by black holes and pulsars — have needed to be as large as they are expensive.
Creating these antimatter beams on a small scale will hopefully give astrophysicists greater insight into the “enigmatic features” of gamma ray bursts that are “virtually impossible to address by relying on direct observations,” according to a paper published at arXiv.
While the blasts only last fractions of a second each, the researchers report each firing produces a particle-density output level comparable to the accelerator at CERN.
