Electrostatic Analyzer for Selection of Homogeneous Ion Beam

Abstract

An electrostatic analyzer has been built for use with the high pressure electrostatic generator at the University of Wisconsin. The proton beam from the generator is deflected through a 90° arc of 40″ radius by means of a radial electric field between curved metal plates spaced 516′′ apart. Suitably disposed slits select a beam which has a very small energy spread. The apparatus has been operated with energy resolutions up to 5000, and preliminary tests have been made, using the 985- and 1020-kv γ-ray resonances in the reaction Al27+H1→Si28+hν.

Single-pulse and multipulse longitudinal phase space and temperature measurements of an intense ion beam

“…Warren first presented a spectrometer, which is capable of measuring the longitudinal beam distribution, in 1947 [16]. The spectrometer consists of a cylindrical electrostatic dipole with a 90 bend (Fig.…”

Diagnostics for intense heavy-ion beams in the HIF-VNL

“…An electrostatic energy analyzer (EEA) is used to measure the beam energy and beam energy distribution. We have used cylindrical 90-degree-bend analyzers with first order focus [7] to measure the time evolution of the mean beam energy in HCX [2] and the rate of charge exchange of beam ions in a gas source on STS-100 [8]. In addition to its utility as an energy analyzer, the EEA can also be used to discriminate and analyze beam ions that have been doubly ionized by interaction with ambient gas.…”
