SUMMARY:Electron Cyclotron Heating in the WHAM device\, Preliminary Ex
 am\, Jonathan Pizzo\, Physics Graduate Student
DESCRIPTION:The Wisconsin HTS Axisymmetric Mirror (WHAM) is an experim
 ent that will study the axisymmetric mirror as a candidate for magneti
 cally confined fusion energy. WHAM will use electron cyclotron heating
  (ECH) for many important functions that are necessary to achieve its 
 physics goals. The ECH system has been designed and built over the pas
 t 4 years to reliably deliver up to 500kW of 110 GHz power into the WH
 AM central cell\, with control over power level\, polarization\, pulse
  length\, and deposition location. When operational\, this will give W
 HAM the highest ECH power density of any plasma device to date. In thi
 s presentation I will discuss the design and construction of the ECH s
 ystem throughout the years\, including the gyrotron\, waveguide transm
 ission line\, launch system\, and other components. I will also discus
 s planned future experiments to be done with ECH on WHAM and the poten
 tial to use off-axis ECH heating to improve the MHD stability of an ax
 isymmetric mirror.
