SUMMARY:Using magnetic fields and microgravity to explore the physics 
 of dusty plasmas\, Plasma Physics (Physics/ECE/NE 922) Seminar\, Ed Th
 omas\, Jr. (Auburn)
DESCRIPTION:Over the last three decades\, plasma scientists have learn
 ed how to control a new type of plasma
\n<br>
\nsystem known as a “c
 omplex” or “dusty” plasma. These are four-component plasma syste
 ms that
\n<br>
\nconsist of electrons\, ions\, neutral atoms\, and cha
 rged\, solid\, nanometer- to micrometer-sized
\n<br>
\nparticles. The 
 presence of these microparticles allow us to “tune” the plasma to 
 have solid-like\,
\n<br>
\nfluid-like\, or gas-like properties. This m
 eans that dusty plasmas are not just a fourth state of matter<br>
\n�
 � they can take on the properties of all four states of matter.<br>
\n
  <br>
\nFrom star-forming regions to planetary rings to fusion experim
 ents\, charged microparticles can be<br>
\nfound in many naturally occ
 urring and man-made plasma systems. Therefore\, understanding the<br>

 \nphysics of dusty plasmas can provide new insights into a broad range
  of astrophysical and<br>
\ntechnological problems. This presentation 
 introduces the physical properties of dusty plasmas –<br>
\nfocusing
  on how the small charge-to-mass ratio of the charged microparticles g
 ives rise to many<br>
\nof the characteristics of the system. In parti
 cular\, dusty plasmas can be used to study a variety of<br>
\nprocesse
 s in non-equilibrium or dissipative systems such as self-organization 
 and energy cascade<br>
\nas well as a variety of transport and instabi
 lity mechanisms. This presentation will discuss results<br>
\nfrom our
  studies of dusty plasmas in high (B ≥ 1 T) magnetic fields using th
 e Magnetized Dusty<br>
\nPlasma Experiment (MDPX) device at Auburn Uni
 versity and in microgravity experiments using<br>
\nthe Plasmakristall
 -4 (PK-4) laboratory on the International Space Station.
