Folded Ferrite Loaded Cavities for Impedance Matching in the AGS

Reduction of the Q-Loss-Effect in Ferrite-Loaded Cavities

The performance of cavities loaded with Ni-Zn ferrites under parallel DC-biasing is often limited by the highloss-effect (HLE) or quality-loss-effect (QLE) [1]. After some milliseconds at fixed frequencies, a sudden drop of the resonator's voltage occurs above a specific threshold level. The mechanism of this loss has not been fully understood yet. At GSI, a simple method has been found to work...

Transverse Impedance Measurement in Rhic and the Ags

The RHIC luminosity upgrade program aims for an increase of the polarized proton luminosity by a factor 2. To achieve this goal a significant increase in the beam intensity is foreseen. The beam coupling impedance represents a source of detrimental effects for beam quality and stability at high bunch intensities. In this paper, we evaluate the global transverse impedance in both the AGS and RHI...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

Impedance Matching Why Impedance Match ?

Also, the power-handling capacity of a transmission line is maximum when it is "flat", i.e., operating at low SWR. Lastly, it is important to be able to interconnect a number of different components into a system, and the only way that can be done reliably and predictably is by constraining the reflection coefficients of the various interfaces through impedance matching. Multiple reflections ca...
