Stable Plasma Jet Created In The Lab For The First Time In History

Maybe you didn’t know, but what you see into the night sky is plasma, an amount of hot atomic particles, to be more precisely. The plasma was studied from the stars and other space forms with the help of telescopes, but now, a new method has been found by scientists. They can recreate the stable plasma jet in the laboratory for more detailed examinations. A team of scientists has created that for the first time.

The team of scientists is composed and led by physicists Lan Gao from the U.S. Department of Energy’s (DOE), Princeton Plasma Physics Laboratory (PPPL), and Edison Liang of Rice University. Together they have recreated for the first time one particular form of the magnetized plasma jet. From this creation, they are hoping to understand how the plasma jets are streaming from the young stars and maybe from the black holes as well. They are especially studying the massive stellar objects that have the key to trap light, space, and time.

However, by creating this stable and robust magnetized plasma jets in the laboratory, they could study more and more astrophysical objects that are light years away from Earth. The plasma jets were created by using the OMEGA Laser Facility from the University of Rochester in the Laboratory for Laser Energetics (LLE). The team has used twenty of OMEGA’s laser into a round shaped area and on a plastic target, where each laser has created little puff of plasma.

Moreover, when the plasma puff has begun to expand, more pressure has been put into the inner region of the shaped area. With the help of that pressure, the plasma jet has reached over four millimeters in length, and a magnetic field was created with the strength of 100 Tesla. To sum up, all the tools used for measurements, temperature, density, lengths, and the magnetic shape, have helped the scientists to make a comparison between the plasma jet from the laboratory and the plasma jet from space objects. After this first experiment, the scientist will expand their research to other types of phenomenon.
