A team of researchers working at the National Ignition Facility, part of Lawrence Livermore National Laboratory, has found that covering a cylinder containing a small amount of hydrogen fuel with a magnetic coil and firing lasers at it triples its energy output—another step toward the development of nuclear fusion as a power source.
In their paper published in the journal Physical Review Letters, the team, which has members from several facilities in the U.S., one in the U.K. and one in Japan, describes upgrading their setup to allow for the introduction of the magnetic coil.
