This paper reports on recent beam measurements of higher order modes in the TESLA Test Facility (TTF) accelerating modules. Using bunch trains of about 0.5 ms with 54 MHz bunch repetition and up to 90 % modulated intensity, transverse higher order modes are resonantly excited when the beam is offset and their frequency on resonance with the modulation frequency. With this method, the trapped mo...
We report experimental studies of bright-state polaritons of four-wave mixing (FWM) and six-wave mixing (SWM) signals through cascade nonlinear optical parametric amplification processes in an atom-cavity composite system for the first time. Also, the coexisting cavity transmission modes of parametrically amplified FWM and SWM signals are observed. Finally, electromagnetically induced absorptio...
This paper investigates the excitation of various natural modes in a magnetized bi-ion or dusty plasma. The excitation is provided by parametrically pumping the magnetic field. Here two ionlike species are allowed to be fully mobile. This generalizes our previous work where the second heavy species was taken to be stationary. Their collection of charge from the background neutral plasma modifie...
The problem of reconstruction of the pulsar magnetospheres nearby the light cylinder surface is studied. It is shown that, on the basis of the Euler, continuity and induction equations, there is a possibility of parametrically excited rotational energy pumping process into the drift modes. As a result, the toroidal component of the magnetic field increases very rapidly. The increment is analyze...
This article presents an analytical study of the dynamics a micromechanical integrating gyroscope with disk resonator. A discrete dynamic model resonator is obtained, taking into account axial anisotropy its mass and stiffness properties, as well action electrical control system oscillations. An analysis spectral problem vibrations in plane carried out. The nonlinear regimes free parametrically...
