HSX Graduate Students

Alexis Briesemeister
Alexis is in charge of installing and getting initial results from the CHERS system.
John Canik
John has been studying the effects of quasisymmetry on particle and heat transport. He has done this by measuring the plasma density and temperature profiles using a Thomson scattering system. He has also performed extensive three-dimensional modeling of the neutral gas in HSX plasma, which has yielded the particle source rate and neutral density.

John received his Ph.D. in Spring of 2007 and currently works at Oak Ridge National Laboratory.

Chris "The Hammer" Clark
Chris has taken the lead on the electron beam probe project resulting in confirmation of theoretical calculations of the magnetic axis shift in different modes.
Walter Guttenfelder
Area - examining fluctuations and anomalous transport in HSX especially through 3-D modeling.
Andrew Herr
Andrew is interested in wall condition in the HSX vacuum vessel. Initial one tesla operation showed radiation of all injected power due to impurity influx. Andrew is currently working on implementing a system to perform and monitor boronization of the vessel. Previously, Andrew worked on the soft x-ray profile diagnostic on HSX. He also maintains a list of plasma physics acronyms.
Jeremy Lore
Jeremy has finished implementing a displacement monitoring system and is now working install the reflectometer diagnostic on HSX.
Huijuan (Jane) Lu
Area - electron cyclotron emission imaging diagnostic to examine electron temperature radial profiles, and electron temperature fluctuations.
Jerahmie Radder
Area - rf heating and design and fabrication of a quasi-optical launching system for the high-power electron cyclotron resonance heating microwaves - 2 gyrotrons, 200 kilowatts each, for 50 to 75 milliseconds.
John Schmitt
Area - plasma flows, electric fields, and flow shear, in biased and non-biased ECRH plasmas.
