Two-Color interferometry as a fluctuation diagnostic on Alcator C-Mod
The two-color interferometer diagnostic on Alcator C-Mod has been upgraded to measure line-integrated electron density fluctuations for turbulence and transport studies. Heterodyne signals from ten vertical-viewing CO2 laser chords are demodulated relative to a local oscillator using high bandwidth …

Propellant Surface Temperature and Plume Characteristics of Micro-Pulsed Plasma Thrusters
… The microPPT plume is characterized using two-color interferometry to simultaneously measure electron and neutral densities during the discharge. As the microPPT operates, the solid propellant recesses into the outer electrode tube, possibly changing thruster performance. Recession shape …

Two-Color Heterodyne Interferometry for PI3 Line-Averaged Plasma Density Measurements
This thesis investigates two-color heterodyne interferometry, which is a technique used for plasma density diagnostics in fusion experiments. Funded through a Mitacs Accelerate internship, this work focused on improving vibration compensation of the existing multi-chord interferometer used at …
