A Transverse RF Deflecting Structure for Bunch Length and Phase Space Diagnostics
A traveling wave transverse rf deflecting structure is discussed as a tool for bunch length measurement and as an aid to detailed phase space diagnostics in future FEL projects. The high frequency time variation of the deflecting fields is used to ‘pitch’ or ‘yaw’ the electron bunch where the resulting transverse beam width measured on a simple profile monitor represents a reliable, single-shot...
متن کاملDeflecting Forces for the Case of Multi Mode Beam - Rf Cavity Interaction in Linear Accelerators
Abstract The formulae for the deflecting rf forces have been derived for the train of charged bunches, traversing a rf cavity. These forces originate from the deflection action of non symmetrical modes excited by the misalined bunches, the infinite set of the cavity eigen modes being taken into account. Various dependencies are explored, including the effect of "mode saturation" and non lineari...
متن کاملBeam Emittance Growth Caused by Transverse Deflecting Fields in a Linear Accelerator*
The effect of the beam-generated transverse deflecting fields on the emittance of an intense bunch of particles in a high-energy linear accelerator is analyzed in this paper. The equation of motion is solved by a perturbation method for cases of a coasting beam and a uniformly accelerated beam. The results are applied to obtain some design tolerance specifications for the recently proposed SLAC...
متن کاملTransverse Beam Dynamics in Plasma-based Linacs
The transverse beam dynamics in plasma channels of possible future plasma-based linacs is discussed. We represent the transverse focusing of both a beam-driven and a laser-driven plasma wake eld accelerator by a uniform focusing channel. The transverse beam sizes and a basic o set tolerance are calculated, nding that sub-micron beams must be transported with even smaller o set tolerances. The r...
متن کاملTransverse and longitudinal beam dynamics studies at the Fermilab photoinjector
The Fermilab photoinjector produces electron bunches of 1–12 nC charge with an energy of 16–18 MeV. Detailed measurements and optimization of the transverse emittance have been carried out for a number of beam line optics conditions, and at a number of beam line locations. The length of the bunches has also been measured, first for an uncompressed beam (as a function of the charge) and then for...
