Products > Cathodes CeBix > Product Information

Applied Physics Technologies exclusively offers CeBix (Cerium hexaboride) cathodes to its customers. CeBix cathodes are ideal for many small spot size applications such as SEM, TEM, surface analysis and metrology, and for high current applications such as microwave tubes, lithography, electron-beam welders, X-ray sources and free electron lasers.

In laboratory tests at Applied Physics Technologies, CeBix has proven to be more resistant to the negative impact of carbon contamination than LaB6, which gives it an edge in potential cathode lifetime. Additionally, the evaporation rate for CeBix at normal temperatures near 1800 K is less than the rate for LaB6. As long as the cathode is being operated below 1850 K, CeBix should maintain the tip shape longer and therefore last longer.'
