YPS Field Emission Sources

Ted Pella has been appointed exclusive distributors for the YPS (York Probe Sources) Schottky Field Emission Sources. The YPS Schottky or thermal field emission (TFE) sources can be used in many brands of focused electron beam systems including SEM, TEM, Auger and CD-SEM systems. The YPS TFE sources are an excellent and cost effective drop-in replacement for existing TFE sources. The YPS TFE source comes as a complete assembly including the pre-centered TFE cathode and a cylindrical suppressor electrode. Normal lifetime for the YPS TFE sources is around 8000 hrs.
