Abstract
A simple, demountable glass field-ion microscope design is described which utilizes a series arrangement of liquid nitrogen cooled zeolite pellet sorption traps that actively pump during operation. This scheme allows atomic surface features of etched wire tips to be continuously observed in a clean He image gas environment with good resolution at liquid nitrogen temperature. The complete design details and operational procedures are outlined to allow the results presented to be duplicated with a minimum effort, and for an investment below $3500. Typical results are illustrated with images of W and W-3% Re.Keywords
