Simultaneous iterative learning control of mode entrainment and error field
Wilkie Choi, Francesco Volpe
It is shown that static error fields (EFs) can severely limit the maximum rotation frequency achievable in mode entrainment by applied rotating fields. It is also shown that the ro…
Large vacuum flux surfaces generated by tilted planar coils
Jessica L. Li, Jacob Austin, Ben Y. Israeli +2
Helical equilibria can be generated by arrangements of planar coils similar to tokamaks, but without a central solenoid and with the toroidal field (TF) coils tilted with respect t…
Passive and active electromagnetic stabilization of free-surface liquid metal flows
S. M. H. Mirhoseini, R. R. Diaz-Pacheco, F. A. Volpe
Free-surface liquid metal flows tend to be uneven due to instabilities and other effects. Some applications, however, require constant, uniform liquid metal thickness. This is for…
Conceptual design of first toroidal electron cyclotron resonance ion source and modeling of ion extraction from it
C. Caliri, D. Mascali, F. A. Volpe
Electron Cyclotron Resonance Ion Sources (ECRIS) progressed to higher and higher ion currents and charge states by adopting stronger magnetic fields (beneficial for confinement) an…
Multi-pole multi-zero frequency-independent phase-shifter
M. A. Bitar, A. Gallo, F. A. Volpe
A multi-pole, multi-zero design allowed realizing a "true" phase-shifter (not time-delayer) of flat frequency-response over more than 3 decades (30Hz-100kHz), which can be extended…
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…
