Transport characteristics of a Glaser magnet for an axisymmetric and nonaxisymmetric space charge dominated beam
Abstract
This paper describes the dynamics of space charge dominated beam through a Glaser magnet which is often used to focus charged particle beams in the low energy section of accelerators and in many other devices. Various beam optical properties of the magnet and emittance evolution that results from the coupling between the two transverse planes are studied. We have derived ten independent first order differential equations for the beam sigma matrix elements assuming the linear spacecharge force consistent with the assumption of the canonically transformed KV like distribution. In addition, the feasibility of using a Glaser magnet doublet in a low energy beam injection line to match an initial nonaxisymmetric high intensity beam with net angular momentum to an axisymmetric system to suppress effective emittance growth after transition back to an uncoupled system, has also been studied.

The predictions of the smoothapproximation theory for the effective radius of a spacecharge dominated beam in a periodic solenoid focusing channel were checked experimentally over a wide range of focusing conditions. Electron beams with an energy of 5 keV and currents of 50 to 70 mA were transported through a 5mlong periodic channel and beam radii were measured by an axially moveable phosphor screen and a chargecoupled device camera. The phase advance of betatron oscillation per period without spacecharge, [sigma][sub 0], was varied from [sigma][sub 0]=45[degree] to [sigma][sub 0]=90[degree]. The tune depression due to spacecharge, [sigma]/[sigma][sub 0], was in themore »

Studies of spacechargedominated multispecies beam in a solenoid based beam transport line
A selfconsistent particleincell (PIC) simulation is used to study the transport properties of a spacechargedominated multispecies beam propagating through a solenoidbased low energy beam transport line. The evolution of the beam radius and emittance growth of each species arising due to the nonlinear spacecharge forces has been investigated. The selfconsistent PIC simulation shows the formation of hollow density profiles of subdominant unwanted species around the primary beam, downstream of the transport line. We have utilized this effect for efficient removal of unwanted species by making use of a slit at a suitable location in the beam line. 
On space charge dominated beam transport without emittance growth
Possible mechanisms of beam emittance conservation in high current transport lines and in RF linacs are discussed. Invariance of beam emittance is treated as a problem of proper matching of the beam with focusing and accelerating channels. To obtain matching conditions for a beam with an arbitrary distribution function in transport channel, it is necessary to accept that the potential of the external focusing field is a highly nonlinear function of radius. The solution for external potential is obtained from the stationary Vlasov{close_quote}s equation for beam distribution function and Poisson{close_quote}s equation for electrostatic beam potential.

Experimental, theoretical, and numerical investigation of the homogenization of density nonuniformities in the periodic transport of a spacecharge dominated beam
The homogenization of a beam with a transversely nonuniform initial density distribution is examined by masking the ouput from a Pierce electron gun into five parallel beamlets, which are then propagated down a channel of periodically spaced solenoid focusing magnets. Experimental measurements, theoretical predictions, and PIC simulations are in excellent agreement for averaged beam quantities such as rms emittance and envelope radius. In addition, the finestructure characteristic of the nonlinear evolution of the beam, including the formation of downstream images, is reproduced in detail by the simulations. 
Generation of spacecharge waves due to localized perturbations in a spacecharge dominated beam
It has been found for the first time in experiments with an electron beam that spacecharge waves can be generated not only in pairs. A single slow wave, a single fast wave, or combinations of the two waves with different amplitude and polarity relations have been produced experimentally in a spacecharge dominated beam. Analytical solutions derived from onedimensional fluid equations show the amplitude and polarity of each spacecharge wave as a function of the initial perturbation parameters. The theory provides the correct interpretation of the experimental observations.
