Bayesian inference of plasma parameters from collective Thomson scattering technique on a gas-puff near stagnation [PDF]
Scientific Reports, 2023 The Collective Thomson scattering technique has been implemented to study the stagnation of a single liner gas-puff. The plasma parameters are determined by theoretically modelling the scattering form factor in combination with Bayesian inference to ...

Direct observations of pure electron outflow in magnetic reconnection [PDF]
Scientific Reports, 2022 Magnetic reconnection is a universal process in space, astrophysical, and laboratory plasmas. It alters magnetic field topology and results in energy release to the plasma.

Neutronics analysis of the ITER Collective Thomson Scattering system [PDF]
Fusion Engineering and Design, 2018 Abstract The Collective Thomson Scattering (CTS) will be the ITER diagnostic responsible for measuring the alpha-particle velocity distribution. Using mirrors, a powerful microwave beam is directed into the plasma via an opening in the plasma-facing wall. The microwaves will scatter off fluctuations in the plasma, and the scattered signal is recorded
