SUMMARY:From ASDEX Upgrade to ITER: Preparing the Next Step in Fusion 
 Research\, Physics Department Colloquium\, Hartmut Zohm\, Max Planck I
 nstitute
DESCRIPTION:Nuclear Fusion research has progressed steadily over the p
 ast 40 years from small table top experiments to large facilities that
  allow to create on earth hydrogen plasmas hotter than the centre of t
 he sun. In the area of magnetic plasma confinement\, the technological
  development goes together with huge progress in the understanding of 
 magnetized hot\, nearly collisionless plasmas\, covering a wide range 
 of phenomena\, the most prominent areas being turbulent transport of h
 eat and particles\, large scale MHD stability and plasma wall interact
 ion. Based on this the Next Step in fusion research\, the ITER experim
 ent\, is aimed at generating significant amounts of fusion power\, i.e
 . at least 10 times the external power used to heat the plasma. The ta
 lk will briefly review our present knowledge of fusion plasma physics 
 and the related fields and then describe the role of the ITER experime
 nt on the way to a fusion reactor. In the second part of the talk\, I 
 will discuss the role of present day fusion experiments in preparing I
 TER\, exemplified by experimental results and plans from the ASDEX Upg
 rade tokamak\, a medium size fusion facility operated by Max-Planck-In
 stitut für Plasmaphysik in Garching. Experimental results from ASDEX 
 Upgrade range from improving central plasma parameters by optimizing c
 onfinement and stability properties to the first successful operation 
 of a fusion machine with plasma facing components fully covered by Tun
 gsten\, the material foreseen for a fusion reactor\, that was achieved
  in ASDEX Upgrade this year.
