174.png

The YPS-174 is the most common standard Schottky field emitter module, equivalent in dimensions to both FEI – and Denka – standard Schottky field emission cathodes. The suppressor aperture has a diameter of 400µm. The emitter protrudes 250µm from the suppressor electrode. The YPS-174 is compatible with thermal field emission sources used on systems from Amray, Hitachi, JEOL, ZEISS/LEO, FEI (pre 2002), PHI and Riber.
