STAIB Electron Sources

Electron sources manufactured by STAIB Instruments are compact, light weight, high performance instruments. The state-of-the-art electron optical design is unique and provides many important benefits.

• Variable spot size, high beam current at the sample, and large working distance.
• Highly stable voltage and current supplies, within 10^-4 or better, current, and beam position.
• Unique electron optical design that is factory pre-aligned and needs no on-site adjustments. Final focusing and beam positioning (X, Y) are easily accomplished, manually or through a remote control box, over the entire operational current and voltage range of the source.
• Low cathode temperature ensures long life and compatibility with pressures up to 10^-4 torr (up to 10^-2 torr with the efficient differential pumping option). Cathode assemblies are field replaceable without disturbing the electron source assembly.
• Unique remote control of beam focus, intensity, and position ensures ease of use, allowing these adjustments at the chamber rather than at the instrument rack.
• Outgassing from the source is not detectable in typical UHV systems.
• Optional beam blanking and fast pulsing, to synchronize the beam or minimize the load on the sample.
• Computer control plug allows gun parameters to be computer controlled.
• Built-in diagnostic capabilities.
• Technical support of the equipment is provided by phone and fax, free of charge.

Electron sources are available from STAIB Instruments across the range of 10 eV - 125 keV. Some models may be upgraded for higher energy and additional options. Special modifications are available to meet the needs of a given experiment. Please contact our office for further information.
