SUMMARY:Fusion Energy\, Solar Flares and Black Holes in the Wisconsin 
 Plasma Physics Lab\, Plasma Physics (Physics/ECE/NE 922) Seminar\, Car
 y Forest\, UW–Madison Physics
DESCRIPTION:Plasma Physics is the overarching discipline describing pl
 asma\, the hot and energetic state of matter that makes up 99% of the 
 visible universe. In my talk I will introduce you the exciting world o
 f experimental plasma physics in which we build devices\, here on Eart
 h that replicate and mimic what we see in the Universe: from fusion en
 ergy powered stars\; planetary and stellar magnetic fields spontaneous
 ly created by flows of plasma and liquid metals\; spontaneous explosiv
 e bursts of plasma in solar flares that hammer our planet\, satellites
 \, and astronauts\; and accretion of plasma onto supermassive black ho
 les that gives rise to the galaxy sized radio jets that accelerate cos
 mic rays in the Universe. Each of these systems is built up from plasm
 as and have processes that can be studied terrestrially\, which is wha
 t we do in the Wisconsin Plasma Lab. Experiments consist of big rooms\
 , heavy equipment like large vacuum chambers\, intense amounts of elec
 tric energy in the form of magnetic fields\, high voltage power\, and 
 microwave heating\, and specialized diagnostics to measure properties 
 of plasma at temperatures greater than 100000 degrees. I will tell two
  stories in my talk. The first will describe a recent experiment we ca
 rried out to investigate how plasma might break away from the magnetos
 phere of our Sun and give rise to the Solar Wind that fills our solar 
 system. This experiment complements a recently launched NASA mission c
 alled Parker Solar Probe that is a satellite that is now probing close
  to the sun. The second will be about revisiting an old idea called th
 e magnetic mirror with new technology for making fusion in a simpler a
 nd more useful way than currently envision in reactors along the path 
 that Iter is going. We are now building a new experiment called the Wi
 sconsin High-Temperature-Superconductor Axisymmetric Mirror (WHAM) at 
 the Physical Sciences Lab to test our ideas.<br>
