 |Introduction              |We have a Varian e-Gun 980-0003, powered by the e-Gun Control Unit Model 922-0020. Read the manuals FIRST before working on the instrument; {{::ebeam:e-Gun Evaporation Source Manual.pdf|here is the e-Gun manual}}, and {{::ebeam:e-Gun Source Control Unit Manual.pdf|here is the Control Unit manual}}. They are short and informative. However the information about changing the filament (in the e-Gun Manual) is a little confusing, and we ended up successfully completing this task using our own method. This guide will explain the steps for how we changed the filament. You'll need several small Allen keys, some flathead screwdrivers, and 0.01" and 0.04" feeler gauges.|
