Buncher Cavity for Erl
نویسنده
چکیده
Design of the buncher cavity for Cornell / JLab ERL project is presented. This is a reentrant spherical copper cavity at a frequency of 1300 MHz. It will be installed between a 500 keV electron gun and superconducting accelerating sections in the injector part of ERL. The cavity has Q of 20,000 and a shunt impedance of 2.1 MOhm. For a design cavity voltage of 200 kV, power dissipated in cavity is as much as 9.6 kW. The cavity has a coaxial loop coupler and will be driven by a 17.5 kW klystron. The estimates of cavity influence on beam dynamics are also discussed.

Design of Three-cavity Coaxial Gyroklystron Circuits for Linear Collider Applications
* Work supported by the US Department of Energy. In this paper we consider the preliminary designs of three-cavity microwave circuits for coaxial gyroklystrons. These tubes are predicted to produce over 100 MW of power in 1 μs pulses in Xand Ku-Band for linear collider applications with efficiencies exceeding 40% and gains above 50 dB. In particular, we examine the effect of first and second ha...
متن کاملDesign of a Multi-Cell Superconducting Cavity for the Cornell ERL Main Linac
The Cornell ERL is a proposed x-ray source. Part of the design of this ERL is the design of the main linear accelerator (linac) by the Superconducting Radio Frequency group at Cornell. One of the main components of this linac is a network of 7-cell superconducting cavities. Each cavity is a resonator that accelerates beams with the electric field of the so-called fundamental electromagnetic mod...

A conceptual design of the input coupler for superconducting injector cavities of Cornell ERL project is presented. The injector cavities are two-cell structures operating at 1300 MHz in CW mode. The coupler has a symmetric design to accommodate requirements for small transverse kick, high RF power delivery to the cavity, and high coupling value. It consists of two identical antenna type couple...

Five rf systems, each operating in cw mode, have so far been specified for the ISAC accelerator system; a prebuncher, an RFQ, a MEBT re-buncher, five DTL cavities and three DTL bunchers. The pre-buncher was designed and built to operate at a frequency of 11.66 MHz plus three harmonics. So far it has operated successfully at full nominal voltage with fundamental plus the addition of two harmonic...
متن کامل6 Ju n 20 01 New 357 MHz Sub Harmonic Buncher
KEK-ATF is doing R&D establishing high-current and low-emittance electron beam for the future linear colliders. In ATF, 15 ps length electron beam is generated by combination of a thermionic gun, a couple of 357 MHz SHBs, and a S-band TW buncher. In the linac, beam instability caused by the fluctuated amplitude and phase of SHBs has been observed. The reason of the fluctuation is considered to ...
