Description

A new imaging system for Electron Cyclotron
Resonance Ion Sources (ECRIS) has been designed
and is being built. This K- and Ka-band camera will
extract localized measurements of absolute energy
and relative number density for ECRIS plasma
electrons by imaging their Electron Cyclotron
Emission (ECE) spectra, as the frequency, shape, and
strength of the ECE harmonics correlate directly with
the local magnetic field, electron energy, and plasma
density. The design of the overall quasi-optical
system will be presented, including novel ceramic
optics for the radial viewports of the Cyclotron
Institute's ECRIS and metamaterial mirrors with
electronically controllable reflectivity. Spatial
resolution sufficient to distinguish important plasma
regions and temporal resolution sufficient to study
dynamic plasma processes is expected.
