FEI FEG Module – Emitter Replacement Service for FEI FE-SEMs
Across the FEI range of FE-SEM models e.g. XL30 FEG/SFEG, SIRION, Quanta FEG, DualBeam, Nova NanoSEM etc) two electron gun types (FEI) are commonly used:
- FEG Module, Re-tip (P/N: 5322 695 16084, 23900)
- Sirion SFEG Module, Re-tip (P/N: 97236)
We stock and refurbish both types (exchange basis). The FEI emitter replacement process comprises of the following key steps:
- Removal of old emitter and physical inspection of exchange FEG module.
- Used emitter replaced with a newly fabricated Thermal Field Emitter (TFE) by YPS.
- Optical alignment of TFE using specialist jigs and testing equipment.
- Technical datasheet detailing key characteristics for TFE supplied (collected by operating the FEG on test system).
- 6” Copper Seal and Technical datasheet provided with each FEG.
- Wooden crates and metal transportation containers are available on request.
This service is aimed at customers who know how to exchange FEG modules, observing standards of UHV cleanliness and high voltage operation.
