Gamma Ray Imager on the DIII-D Tokamak

This is a technical paper concerning the design and commissioning of a gamma ray camera on the DIII-D tokamak. The diagnostic, the Gamma Ray Imager (GRI), is a pinhole camera constructed of lead. This diagnostic is being used to study the behavior of relativistic electron beams in magnetically confined fusion plasmas. Gamma rays can be…

Keeping Fusion Plasmas Hot

The following article first appeared as David C. Pace, William W. Heidbrink, and Michael A. Van Zeeland, “Keeping Fusion Plasmas Hot,” Physics Today 68, 34 (2015). In the article, we discuss interactions between high energy ions and electromagnetic waves in magnetically confined plasmas. These plasmas are produced in nuclear fusion reactors known as tokamaks. My research…

Energetic Ion Loss Detector on the Alcator C-Mod Tokamak

This paper describes the Fast Ion Loss Detector (FILD) at the Alcator C-Mod tokamak. The FILD captures ions that are accelerated to high energies due to radio wave power injection into C-Mod. A couple of neat things about this diagnostic are that it is made of the same molybdenum material as the walls in C-Mod, and…
