Title: Beam dynamics studies for transverse electromagnetic mode type rf deflectors

Abstract

We have performed three-dimensional simulations of beam dynamics for transverse electromagnetic mode (TEM) type RF deflectors: normal- and super-conducting. The compact size of these cavities as compared to the conventional TM₁₁₀ type structures is more attractive particularly at low frequency. Highly concentrated electromagnetic fields between the parallel bars provide strong electrical stability to the beam for any mechanical disturbance. An array of six 2-cell normal conducting cavities or a single cell superconducting structure is enough to produce the required vertical displacement at the target point. Thus, both the normal and super-conducting structures show very small emittance dilution due to the vertical kick of the beam.

Beam self-excited rf cavity driver for a deflector or focusing system

Conference Wadlinger, E A

A bunched beam from and accelerator can excite and power an rf cavity which then drives either a deflecting or focusing (including nonlinear focusing) rf cavity with and amplitude related to beam current. Rf power, generated when a bunched beam loses energy to an rf field when traversing an electric field that opposes the particle`s motion, is used to drive a separate (or the same) cavity to either focus or deflect the beam. The deflected beam can be stopped by an apertures or directed to a different area of a target depending on beam current. The beam-generated rf power canmore »« less

Ultrafast harmonic rf kicker design and beam dynamics analysis for an energy recovery linac based electron circulator cooler ring

Journal Article Huang, Yulu ; Wang, Haipeng ; Rimmer, Robert A. ; ... - Physical Review Accelerators and Beams

An ultrafast kicker system is being developed for the energy recovery linac (ERL) based electron circulator cooler ring (CCR) in the proposed Jefferson Lab Electron Ion Collider (JLEIC, previously named MEIC). In the CCR, the injected electron bunches can be recirculated while performing ion cooling for 10–30 turns before the extraction, thus reducing the recirculation beam current in the ERL to 1/10–1/30 (150mA–50 mA) of the cooling beam current (up to 1.5 A). Assuming a bunch repetition rate of 476.3 MHz and a recirculating factor of 10 in the CCR, the kicker is required to operate at a pulse repetitionmore »« less

A 3-cell deflecting rf cavity for emittance exchange experiment at ANL.

Journal Article Power, J G ; Jing, C ; Kim, K J ; ... - Nucl. Instrum. Methods Phys. Res. A

An RF deflecting structure has been designed and fabricated for a transverse-to-longitudinal emittance exchange experiment at Argonne National Laboratory (ANL) [Y.-E. Sun, et al., Design study of a transverse-to-longitudinal emittance exchange proof-of-principle experiment, in: Proceedings of PAC-2007, Albuquerque, NM, USA, 2007, pp. 3441-3443]. The structure is a 1300 MHz normal conducting RF cavity consisting of three cells operating in a dipole (TM{sub 110}-like) mode. As high as 3.4 MV deflecting voltage is required for the experiment. In this paper, we present detailed RF design of the cavity, particle tracking simulations in the cavity and low power RF measurement results inmore »« less
Investigation of an Ultrafast Harmonic Resonant RF Kicker

Thesis/Dissertation Huang, Yulu

An Energy Recovery Linac (ERL) based multi-turn electron Circulator Cooler Ring (CCR) is envisaged in the proposed Jefferson Lab Electron Ion Collider (JLEIC) to cool the ion bunches with high energy (55 MeV), high current (1.5 A), high repetition frequency (476.3 MHz), high quality magnetized electron bunches. A critical component in this scheme is a pair of ultrafast kickers for the exchange of electron bunches between the ERL and the CCR. The ultrafast kicker should operate with the rise and fall time in less than 2.1 ns, at the repetition rate of ~10s MHz, and should be able to runmore »« less
