A theoretical investigation of radiation field produced by a charge moving through the dielectric concentrator for Cherenkov radiation is performed for the general case where a charge trajectory is shifted with respect to the target axis. The idea of dielectric target with specific profile of the outer surface was presented and investigated in our previous papers for the symmetric case. Here we show how non-symmetric field components generated in the bulk of target affect field distribution near the focus where strong concentration of the energy occurs. Possible applications of this target are discussed. arXiv:1904.05188v3 [physics.acc-ph]

“…Accelerator structures, and are considered as an advanced prospective technology to adjust the frequency of high power high gradient dielectric accelerating structures, such as wakefield accelerators [1,2]. The frequency is varied in the waveguide structure by placing a ferroelectric layer (ε ∼ 400-500; thickness t ∼ 200 μm) between a layer of linear dielectric ceramic (ε ∼ 10-100, t ∼ 2 mm) and the outer conducting skin of the waveguide.…”

Tunability and leakage currents of (Ba,Sr)TiO3 ferroelectric ceramics with various additives

The Ba x Sr 1−x TiO 3 ferroelectric ceramics with magnesium (BSM) and neodymium (BSN) additives were studied. Measurements were made of tunability, dielectric losses (tan δ), leakage currents, the correlations between current-voltage I (U ) and capacitance-voltage C(U ) characteristics. I (U ) characteristics of high quality BSM ceramics have four regions: Ohmic, where the conductivity is linear; the horizontal region (or negative differential resistivity); the exponential dependence; and the vertical current enhancement. These BSM samples (∼20% Mg additives) were distinguished by highest breakdown strength (more than 1000 V), low tan δ (less than 10 −3 at 1 MHz) and high tunability (up to 10% at E max ∼2 V/μm).

“…The advantage of the dielectric wakefield accelerator is that it operates at a much lower frequency than the plasma wakefield accelerator that is suitable for obtaining large transformer ratio through a desired pulse shaping. Ferrite loaded waveguide was also proposed for wakefield acceleration [11][12][13] as an alternative to dielectric wakefield acceleration. However, the ferrite loaded waveguide was more susceptible to dielectric breakdown and less popular in comparison to dielectric wakefield accelerator.…”

Abstract-A dual grating waveguide accelerator structure is investigated and compared with the dielectric wakefield accelerator at THz frequencies. In a dielectric wakefield accelerator, thinner liners for a given current and liners having lower dielectric constant are not preferable due to the fact that they generate much lower axial wakefields. This limits the operation of the device at THz. On the other hand, it is shown that a grating waveguide is tuned at THz with shallower slot heights with competitive wakefield gradients than a dielectric wakefield accelerator.
