Description

YPS Schottky TFE sources

YPS supplies standard designs, refurbishes legacy designs and designs and supplies custom TFE sources. These products are aimed to customers who are comfortable with changing field emission sources and know how to change, load and align the TFE sources in a clean environment. Operating vacuum for Schottky TFE sources is typically better than 1×10-9mbar. This is higher than the operating vacuum for tungsten or Lab6 sources, but less stringent than for cold field emission sources. The YPS Schottky thermal field emission sources exhibit excellent stability over a wide range of acceleration voltages and long operating times. Electron Source Performance Table

YPS-174 Standard Schottky TFE emitter module

The YPS-174 Schottky TFE module is a drop-in replacement for the most common standard Schottky thermal field emitter module. It is equivalent in dimensions with both Denka and FEI standard Schottky field emission cathodes. The supprossor aperture has a diameter of 400µm. The emitter typically protrudes 250µm from the suppressor electrode. The YPS-174 is covmpatible with thermal field emission sources used on E-beam systems from AmRay, Hitachi, JEOL, Zeiss, LEO, Philips, PHI and Riber. Dimensions of the YPS-174 TFE module
