SUMMARY:“The Challenge of Fusion - Being Caught between Plasma and W
 all"\, Plasma Physics (Physics/ECE/NE 922) Seminar\, Dr. Jan W. Coenen
 \, Institute for Energy and Climate Research (IEK-4)\, Juelich\, Germa
 ny\; and UW-Madison
DESCRIPTION:Making nuclear fusion a reality faces a pivotal challenge 
 at its core – striking the delicate balance between containing and s
 tabilising the intensely hot plasma within a fusion reactor while safe
 guarding the surrounding wall materials from extreme heat and radiatio
 n. This balance is critical for realising fusion as a clean and sustai
 nable energy source. Here\, we elaborate on the scientific\, engineeri
 ng\, and materials aspects of this challenge\, highlighting innovative
  solutions and ongoing research efforts with a focus on the plasma wal
 l interface.<br>

\nBio<br>
\nDr. Coenen completed his Ph.D. at
  Heinrich Heine University Duesseldorf in 2006\, and since then\, he h
 as been deeply involved in the field of plasma physics and materials\,
  particularly in the context of extreme environments like those encoun
 tered in nuclear fusion. He holds the role as a project leader at the 
 Institute for Energy and Climate Research (IEK-4)\, research center Ju
 elich in Germany. In this capacity\, he leads the development of mater
 ials and components capable of withstanding the extreme conditions ass
 ociated with nuclear fusion.
\n<br>
\nWith over a decade of experience
  in this domain\, Dr. Coenen has been instrumental in devising innovat
 ive solutions utilising high-Z metal composite materials\, notably tun
 gsten\, known for their exceptional resilience against high temperatur
 es\, radiation\, and erosion.
\n <br>
\nMoreover\, Dr. Coenen plays a 
 vital role in coordinating European initiatives related to plasma-wall
  interaction and the qualification of high-Z materials for future fusi
 on devices\, including ITER\, JET\, AUG\, and W7-X. These projects are
  pivotal in the field of nuclear fusion research and development.
\n <
 br>
\nHis contributions extend internationally as he is part of a grou
 p of experts within the International Tokamak Physics Activity (ITPA-D
 iv/Sol)\, working to enhance the knowledge base required for the opera
 tion of ITER\, a significant international fusion research project.
\n
  <br>
\nDr. Coenen's academic influence is also noteworthy\, as he hol
 ds adjunct professorships at UW Madison\, an honorary professorship at
  the Chinese South West Institute (SWIP)\, and serves as a lecturer at
  the University of Bochum in Germany. These academic appointments unde
 rscore his dedication to both teaching and advancing research in the f
 ield.
