Beam-beam interaction in FCC-ee can be seriously affected by the vacuum chamber coupling impedance resulting in a safe tune areas reduction, tune shifts and spread, bunch length and energy spread variation. The interplay of the two effec... Y Zhang,M Migliorati,M Zobov - 《Journal of Physi...
parietal and occipital poles, where consistent activations in response to cVEP stimulation are expected10,15. The ground (GND) and reference (REF) electrodes were located at AFz and FCz, respectively (Fig.2). Conductive gel was applied at each electrode site and impedances were kept below 2 ...
where Vi represents the signal strength of electrode i, Z(ω) is the transfer impedance of a BPM pickup electrode depending on the design, I(ω) is the beam spectrum, and s is a sensitivity function. Compared to s, which determines the signal strength on an electrode, we are more conce...
multi-beam relativistic klystron amplifier (CMB-RKA), in which (i) the perveance is reduced by the multi-beam to improve efficiency; (ii) the fundamental-mode coaxial cavity enhances the characteristic impedance (R/Q) and coupling coefficient (M) to achieve high-efficiency beam-wave interaction...
These mirrored L-slots effectively mitigate the open stopband phenomenon and thus improve the impedance matching and realized gain of the antenna at the broadside radiation frequency. Third, a rapid method for developing periodic leaky-wave antennas is demonstrated for the first time. This method is...
The E-plane T-junction is employed to realize 3 dB power divider in the broadband. To achieve good input impedance matching in a wider bandwidth, the rectangular groove is adopted in the symmetry plane of T-junction, the diagram of T-junction is shown inFigure 5d. Unlike the triangular wed...
Beam 4 is the output port and terminated by a load of impedance 𝑧𝐿zL. Transmission into this port is described by the scattering parameter 𝑆21S21. Additional loads are provided to damp the motion of the outer beams; for simplicity, these are also 𝑧𝐿zL. We now show that this...
