Although the magnetic field created during such an experiment lasted only a matter of nanoseconds, this period would be sufficient for modern physics experiments.
According to living science reports, it will be possible to generate magnetic fields comparable to those that exist in neutron stars and black holes, according to a new literature study.
According to media outlets, although no one has surpassed the results of the 2018 lab experiment where lasers were employed to create a magnetic field “1 kilotasla” (1,000 Tesla; to put it in perspective), magnetic resonance imaging machines used in hospitals typically have a magnetic field of about 1 Tesla. ), New research suggests that it is possible to generate megatasla (1 million Tesla) field.
Using computer simulation and modeling, the researchers found that shooting “ultra-inert laser pulses” on a hollow tube could stimulate electrons in the wall of a tube a few microns in diameter and cause the tube to “expand”. Pre-existing magnetic field by two-three orders “.
And although the Megatesla magnetic field will shrink after about 10 nanoseconds, media outlets have noted that “there is plenty of time for modern physics experiments, which often deal with particles and conditions that blink much less than the blink of an eye.” .
Researchers also argue that such an experiment should be possible with the technology currently available, as it should have a “laser system with a pulse energy of 0.1 to 1 kJ and a total power of 10 to 100 watts.” LiveScience added that ten-watt lasers have “already been set up as part of the European Extreme Light Infrastructure”, and that scientists in China are “demanding the creation of 100 sub-watt lasers known as Extreme Light Stations”.
“The concept promises to open new frontiers in many branches of basic physics and applications in terms of ultrahigh magnetic fields,” the authors of the study, published in Scientific Reports, said in an abstract word of their work.
