Diagnostics
Phosphorus screen
- Startup diagnostic to to track electrons in the stellarator field - map out flux surfaces
Multiple external electrostatic probes
- Average electron density
- Poloidal and toroidal structure of perturbations (diocotron modes)
Edge gridded energy analyzer
- Electron distribution function information - Te
- Determination of maximum electron energy confined by the device
Internal diagnostics (perturbative)
- Helium puff (electron excitation of helium lines)
- Miniaturized internal probes
- Development of new diagnostics
-
