APTech LaB₆/ CeBix™ Rebuilding Services

Certain cathode types are very expensive to purchase.  Some e-beam lithography systems use a full Vogel mount cathode with a very complicated structure.  Some Auger systems require the cathode and grid cap be assembled with very high precision using specialized equipment.  As a service to our customers, Applied Physics Technologies refurbishes used cathodes of these types at a fraction of the price of a new cathode.  The used cathode or grid cap assembly is first disassembled and all parts that are to be reused are carefully inspected and cleaned.  The unit is then reassembled with whatever new parts are necessary.  In the case of grid cap assemblies, the cathode tip is properly aligned and the spacing with the cap is adjusted to the original manufacturer's specifications.

CeBix™ - An APTech Exclusive

Available exclusively from Applied Physics Technologies, CeBix (ultra-high purity cerium hexaboride) is characterized by 30% to 70% longer lifetimes and better contamination resistance.  For an additional charge, you may have your cathode rebuilt with a CeBix crystal instead of a LaB6 crystal.
