Miniature Evaporation System
e-Vap 3000 system

MDC’s 3kW Electron Beam Source is a versatile and economical deposition tool used for thin film coating processes in high and ultrahigh vacuum environments. The e-Vap® 3000 system evaporates virtually all rare earth refractory and dielectric materials. It provides researchers a simple, relatively low-cost means of depositing high purity thin film coatings. The source is manufactured using all metal sealed gaskets, is extremely compact and has a high level of ruggedness, reliability and efficiency. The compact source design allows the entire source assembly to fit through a 2.75" Del-Seal™ CF port opening and eliminates internal water and electrical connections. This 3kW source is available free standing or as a complete turnkey system. The filament/emitter assembly has a heat-sink and features a unique single piece high voltage insulator design. The entire emitter assembly slides out for easy maintenance. 

A new 3kW Switching Power Supply is available to drive these miniature sources. State-of-the-art switching technology renders a compact rack mountable power supply. The built-in source controller also employs switching technology and provides extremely accurate power control. MDC recommends using crucible liners with all e-Vap® evaporation sources. These liners offer improved thermal stability while reducing the transfer of heat to the crucible. Liners provide the ability to easily and quickly switch evaporant materials without removing the crucible for cleaning. They also reduce power requirements to achieve specific evaporation rates. For detailed list of crucible liner materials go to crucible liners.
