Instead of a wire filament, the TUBO source uses a tubular filament that encloses the entire crucible. The heating current flows along the source axis, up through the heat insulation shields and down through the filament. The crucible temperature is controlled via a thermocouple at the bottom of the crucible. This concept enables a reproducible temperature control of a standard effusion source at a high temperature range so far only accessible with e-beam evaporation. For extremely high temperatures, the TUBO-e includes an electron emission booster heater.

Linear shutter are used for the most demanding applications in production MBE. The design is based on CreaTec`s EDGE toolkit, allowing linear motion without gliding friction. The shutter does not contain PEEK, bronze, permanent magnets or other UHV problematic materials or substances. It is made entirely from stainless steel. Endurance tests have shown failure free operation with practically no wear of the UHV mechanism after more than 10 million strokes at high speed (~2 Hz test frequency over several months).

CreaTec designs and manufactures highly customized heating systems for any kind of application. Temperatures up to 1300°C are standard and temperatures up to 2000°C are possible on small area sizes.

CreaTec designs and manufactures highly customized Quartz Rod Heaters. The equipment is designed for rapid heating avoiding contamination by resistive heaters. Only the sample region is heated. It can be used with any gases (i.e. Oxygen) and in abrassive atmospheres. Compared to laser applications no additional safety precautions are required.
