Colorado State University produces first ultracold neutral plasma with electron temperature below 1 kelvin
Researchers at Colorado State University have, for the first time, produced an ultracold neutral plasma by combining laser cooling techniques with strong magnetic fields. Measurements show that the electron temperature in this plasma is less than 1 kelvin above absolute zero, making it one of the lowest electron temperatures ever measured in a plasma. The research was published in Physics of Plasmas. The new method proposed in the paper helps test plasma theories under more controllable experimental conditions and improve computational models of plasma behavior in extreme environments. The researchers believe this achievement could contribute to future fusion energy...
