UHV E-Beam Sources
For the highest purity thin films, ultra-high vacuum or near ultra-high vacuum environments are necessary. Some of the applications are MBE, surface analysis, mono-layer and high other high purity film needs. Telemark has a complete line of ebeam sources (e-gun) for these applications.
Telemark offers 26 different models of e-beam sources, each with many crucibles options. This decision tree can help you find the right source for your situation. Telemark E-beam Source Model Decision Tree
