Performance of a high brightness field ionization ion source
Description
A Gas Phase Field Ionization Ion Source has been built specifically for use with the University of Melbourne Proton Microprobe. The source is extremely bright making it suitable for use with high resolution probe forming systems. Beam current stability and emitter lifetime is greatly enhanced by the use of iridium field emitters, allowing for reproducible source performance. Current output as a function of source parameters has been measured indicating that nano amps of current are available in a beam up to 105 times brighter than that presently used in the Melbourne probe
