On October 18th,a research team from the University of Erlangen Nuremberg in Germany successfully manufactured the world's smallest particle accelerator,which is only 0.2 millimeters long and can be mounted on a pen tip.The relevant research results have been published in the journal Nature.

  This device is the first micro accelerator capable of quickly and well focused electron beam generation,capable of accelerating electrons to 100000 kilometers per second.The accelerator uses light waves to accelerate particles,forming a narrow electron beam through thousands of 2-micron high silicon columns arranged in two parallel lines.When they produced a version that was 0.5 millimeters long,they found that it could accelerate electrons at a faster speed,increasing the energy carried by electrons by 43%.
  This new technology is expected to be applied in the medical field,providing doctors with new treatment tools or small disinfection tools for biological laboratories.This innovation provides new possibilities for the medical field,and in the future,we can look forward to more research and applications on small particle accelerators.
