The QUAD-EV series is available in five models: M-EV (1 x 1000mm3), M-EV-ANGLED (1 x 1000mm3), QUAD-EV-C (4 x 390mm3), QUAD-EV-90 (4 x 390mm3) and QUAD-EV-HP (4 x 1000mm3).
The Mantis EV Series mini e-beam evaporators are constructed from high-quality, strictly UHV-compatible materials and are fully bakeable to 250°C. The mounting hearths for the source materials and the surrounding evaporation head are highly efficient cooled, ensuring a rapid heat transfer to the cooling water. This allows all but the emission filament and the source material to remain at near ambient temperature, effectively eliminating the structural outgassing which often presents a problem with traditional electron beam evaporators, effusion cells and thermal evaporation boats.
All of the M-EV and QUAD-EV models have integrated flux monitoring plates. These provide real-time feedback of the deposition rate and also can be used in a closed loop control for absolute rate stability and control. The flux monitoring plates are located at the top of the source and below the shutter and can provide an accurate reading of the evaporation rate even with the shutter closed.
The QUAD-EV evaporators use independent filaments, flux-monitoring plates and high-voltage connections to allow each material to be evaporated independently of the other three. The QUAD-EV-C is employed to allow independent co-evaporation of up to four materials. Since each material uses and independent high-voltage connection, the evaporator will still function if a short-circuit occurs. The power supplies are of a rugged construction, enabling seamless operation without malfunction during discharges between the filament and source material (as can happen during initial operation after pump-down).
All evaporators can be equipped with either rods or crucibles interchangeably. The choice depends on the evaporation rate required, the material capacity required and the properties of the source material. Please contact us for recommendations.
All e-beam models utilize a user filament that can be replaced quickly.
