Abstract

In order to develop a high brightness ion source using plasma, the ion beam extraction system with an aperture of $100{\mu}m$ in diameter has been designed and constructed. It is observed that over 500nA of He ion beam current can be extracted. With such an optimized condition, $\~10^3\;A/cm^2sr$ beam brightness can be measured by emittance scanner, which is believed to be a promising result for developing next generation FIB.
