2018 journal article

High resolution magnetic field measurements in hydrogen and helium plasmas using active laser spectroscopy

Review of Scientific Instruments, 89(10), 10D126.

By: A. Zafar n , E. Martin* & S. Shannon n 

TL;DR: The diagnostic relies on measuring a high resolution spectral profile using Doppler-free saturation spectroscopy (DFSS) and then fitting the spectrum to a quantum mechanical model and has been successfully employed to measure the magnetic field in magnetized, low-temperature, high-density, hydrogen and helium plasmas.

2014 journal article

Probing the plasma near high power wave launchers in fusion devices for static and dynamic electric fields (invited)

Review of Scientific Instruments, 85(11), 11E301.

By: C. Klepper *, E. Martin n, R. Isler *, L. Colas *, M. Goniche *, J. Hillairet *, S. Panayotis*, B. Pegourié* ...

Contributors: C. Klepper *, E. Martin n, R. Isler *, L. Colas *, M. Goniche *, J. Hillairet *, S. Panayotis*, B. Pegourie* ...

TL;DR: An exploratory study was carried out in the long-pulse tokamak Tore Supra to determine if electric fields in the plasma around high-power, RF wave launchers could be measured with non-intrusive, passive, optical emission spectroscopy, with a focus on the use of the external electric field Stark effect.

2013 journal article

Dynamic Stark Spectroscopic Measurements of Microwave Electric Fields Inside the Plasma Near a High-Power Antenna

PHYSICAL REVIEW LETTERS, 110(21).

By: C. Klepper *, R. Isler *, J. Hillairet *, E. Martin n, L. Colas *, A. Ekedahl *, M. Goniche *, J. Harris * ...

TL;DR: Fully dynamic Stark effect visible spectroscopy was used for the first time to directly measure the local rf electric field in the boundary plasma near a high-power antenna in high-performance, magnetically confined, fusion energy experiment, and confirmed that the electric field direction deviates substantially from the direction in which it is launched by the waveguides.
