Scientists Create Clearer Images with New Plasma Technique

Topic: Physics

Researchers from Czech Technical University and University of Michigan used a new plasma technique to accelerate protons to 3 mega electron volts. This breakthrough will help scientists create clearer images of ultra-fast events in plasmas.

Plasma pinches are current-carrying columns of ionized gas that can be compressed by their own magnetic field. Scientists have been studying these pinches for years, hoping to achieve controlled nuclear fusion.

In a recent study, researchers used a hybrid X-pinch configuration to create a clearer image. This technique emits protons from a short pinch column, producing a more focused source of radiation. The team accelerated protons to 3 mega electron volts (MeV) on relatively small-scale devices operating at a 400-kiloampere (kA) peak current.

The researchers conducted experiments on two pulse generators: the MAIZE facility at University of Michigan and the XP facility at Cornell University. Both facilities operated at a maximum of 400 kA. The new technique will allow more laboratories to conduct proton radiography experiments, opening up new opportunities in high-energy-density plasma research and fusion science.

The study was led by Ryan McBride from University of Michigan and published in Physical Review Letters and Physics of Plasmas.
