RF plugging of multi-mirror machines
Tal Miller, Ilan Be'ery, Eli Gudinetsky +1
One of the main challenges of fusion reactors based on magnetic mirrors is the axial particle loss through the loss cones. In multi-mirror (MM) systems, the particle loss is addres…
Rate equations model for multiple magnetic mirrors in various thermodynamic scenarios
Tal Miller, Ilan Be'ery, Ido Barth
Axial particle loss is one of the main challenges for fusion aimed, linear magnetic mirror plasma configurations. One way to mitigate this disadvantage and increase the confinement…
Multi-frequency Raman amplifiers
Ido Barth, Nathaniel J. Fisch
In its usual implementation, the Raman amplifier features only one pump carrier frequency. However, pulses with well-separated frequencies can also be Raman amplified while compres…
Kinetic simulations of ladder climbing by electron plasma waves
Kentaro Hara, Ido Barth, Erez Kaminski +2
The energy of plasma waves can be moved up and down the spectrum using chirped modulations of plasma parameters, which can be driven by external fields. Depending on whether the wa…
Plasma Wave Seed for Raman Amplifiers
Kenan Qu, Ido Barth, Nathaniel J. Fisch
It is proposed to replace the traditional counterpropagating laser seed in backward Raman amplifiers with a plasma wave seed. In the linear regime, namely, for a constant pump ampl…
Reducing parametric backscattering by polarization rotation
Ido Barth, Nathaniel J. Fisch
When a laser passes through underdense plasmas, Raman and Brillouin Backscattering can reflect a substantial portion of the incident laser energy. This is a major loss mechanism, f…
Beyond nonlinear saturation of backward Raman amplifiers
Ido Barth, Zeev Toroker, Alexey A. Balakin +1
Backward Raman amplification is limited by relativistic nonlinear dephasing resulting in saturation of the leading spike of the amplified pulse. Pump detuning is employed to mitiga…
Ladder Climbing and Autoresonant Acceleration of Plasma Waves
Ido Barth, Ilya Y. Dodin, Nathaniel J. Fisch
When the background density in a bounded plasma is modulated in time, discrete modes become coupled. Interestingly, for appropriately chosen modulations, the average plasmon energy…
Quantum phenomena in a chirped parametric anharmonic oscillator
Ido Barth, Lazar Friedland
The parametric ladder climbing (successive Landau-Zener-type transitions) and the quantum saturation of the threshold for the classical parametric autoresonance due to the zero poi…
Two-photon ladder climbing and transition to autoresonance in a chirped oscillator
Ido Barth, Lazar Friedland
The two-photon ladder climbing (successive two-photon Landau-Zener-type transitions) in a chirped quantum nonlinear oscillator and its classical limit (subharmonic autoresonance) a…
Quantum and Classical Chirps in an Anharmonic Oscillator
Yoni Shalibo, Ya'ara Rofe, Ido Barth +4
We measure the state dynamics of a tunable anharmonic quantum system, the Josephson phase circuit, under the excitation of a frequency-chirped drive. At small anharmonicity, the st…
Quantum Fluctuations in the Chirped Pendulum
K. W. Murch, R. Vijay, I. Barth +4
An anharmonic oscillator when driven with a fast, frequency chirped voltage pulse can oscillate with either small or large amplitude depending on whether the drive voltage is below…
