Profiles in Diagnostics: A Hot Pursuit to Understand ICE

Kathreen Thome studies how particles travel through fusion plasmas using high frequency magnetic fluctuations known as ion cyclotron emission (ICE). The tokamak approach to magnetic confinement fusion uses a toroidal solenoid to confine high temperature plasmas. With peak plasma temperatures above 100 million degrees Celsius, no physical measurements are possible beyond the very edge of…
