Electron Source ES 40C1
Scanable electron source with small spot profile.
Manufacturer
Prevac
Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.
Key Features
- Fine focus microformed tip cathode
- Scannable electron source with a small spot profile
- Correction of incident electron beam angle (provided by ES40-PS power supply)
- Integrated scan and deflection unit
Description
Due to the high transmission of its Einzel-Lens, the ES 40C delivers a high electron beam current over a wide energy range. The ES 40C1 is designed for a stable and reliable operation in e.g. AES, scanning applications, imaging, EELS and electron pulse or desorption experiments (ESD).
