Laser used to generate 700 Tesla magnetic field to guide laser fusion | NextBigFuture.com

A laser-driven capacitor–coil target was used to generate a strong 600-700 Tesla magnetic field. The strength of the magnetic field was measured on GEKKO-XII23,24, LULI200025, Shengguang-II26, and OMEGA-EP laser facilities. Experimental results revealed that a 600–700-T magnetic field was generated by using a tightly focused kilo-joule and nano-second infrared (λL = 1.053 μm) laser beam. A diverging relativistic electron beam (REB) will be guided to a dense core. The gyroradius of a 1-MeV electron under the influence of a 1-kT (1000 tesla) magnetic field is 5 μm (microns), which is smaller than a typical core radius (20 μm – microns). A kilo-Tesla-level magnetic field is
