Interferometer
Interferometer
- The He-Ne interferometer provides a line-averaged electron density.
CUTOFF Probe
CUTOFF Probe
- In non-magnetized plasmas, there is a electro-magnetic dispersion relation from which we obtain a 'cutoff' frequency which is a function of electron density. This phenomenon can be used as a usuful diagnostics diagnosing plasma density.
- Images from KHYou, et al., Thin Solid Films (2013).
Simulation efforts
Simulation efforts
- BOUT++ is a open source, a framework for writing fluid and plasma simulations in curvilinear geometry.
- BOUT++ is used to better understand linear instabilites and its relations to nonlinear effects such as turbulence and magnetic reconnection.
