DESCRIPTION:Prof. Per Helander\, Max Planck Institut\, Greifswald\nAccordi
 ng to Ampere's law\, curl B = J\, an electric current produces rotation of
  magnetic field lines. In 1951\, legendary astrophysicist Lyman Spitzer di
 scovered that magnetic field lines may actually wind around each other eve
 n if J=0\, a result later rediscovered in other guises\, such as the "Berr
 y phase" in quantum mechanics. Spitzer proposed to use it as a key to achi
 eve fusion energy in the laboratory\, where it provides a way of thermally
  insulating a thermonuclear plasma from the surroundings in steady state. 
 His idea has recently been put to a billion-euro test by the Max Planck So
 ciety in the Wendelstein 7-X experiment. In this lecture\, I will explain 
 Spitzer's fundamental insight and describe this latest experiment in the w
 orldwide quest for fusion energy.\n\nMaster students in physics are partic
 ularly encouraged to attend this talk which should be enjoyable to non-spe
 cialist physicists.
