Photodiode based multi-modal diagnostic for low-energy neutral beam injection in the LTX- spherical tokamak
A. Maan, Tosh Le, D. P. Boyle +8
We present a compact photodiode-based diagnostic array developed to study low-energy neutral beam injection in the LTX- spherical tokamak. The in-vacuum diagnostic combines filt…

Metamaterial lens of specifiable frequency-dependent focus and adjustable aperture for electron cyclotron emission in the DIII-D tokamak
K. C. Hammond, W. J. Capecchi, S. D. Massidda +1
Electron Cyclotron Emission (ECE) of different frequencies originates at different locations in non-uniformly magnetized plasmas. For simultaneous observation of multiple ECE frequ…

Reverse Chromatic Aberration and its Numerical Optimization in a Metamaterial Lens
W. J. Capecchi, N. Behdad, F. A. Volpe
In planar metamaterial lenses, the focal point moves with the frequency. Here it is shown numerically that this movement can be controlled by properly engineering the dimensions of…
