Abstract
A microprocessor controlled Field Emission Microscope is presented. It is capable of measuring changes in work function on different single crystal surfaces present on a field emission tip. During experiments the tip temperature can be measured with an accuracy of 1K. The field emission set up was tested with a series of experiments in which hydrogen was desorbed from a few selected rhodium surfaces.
