E-beam processing is a powerful technique
for enhancing and improving the properties of advanced materials. FMT has successfully used E-beam
for:
●
joining ceramic to super-alloy;
●
improving electric breakdown field in OFE copper and Stainless Steel
electrodes; and
●
reducing dark current in OFE electrodes.
Photographs:
Left: An electron beam system designed to generate an intense pulsed
electron beam for material processing. Processing can be in single or multiple shot modes. The electron beam system is
presently used for irradiating metal components to suppress electrical
breakdown at high voltage, reduce undesirable electron emission and shorten
conditioning time of RF components.
Right: Comparison of the same surface location
before and after electron beam irradiation. Each photo extends 0.15 mm ´ 0.22 mm in actual dimensions. Breakdown measurements on
the optimally irradiated surfaces produced an average breakdown of 109 MV/m
while the non-irradiated surfaces had an average breakdown value of 58
MV/m, an 88% improvement.
