Hanks HM2 Hydra e-Gun™

The Hydra design consists of a compact array of crucibles and electron emitters which translate linearly with respect to each other to provide for the co-deposition of up to six different materials simultaneously.


The Hydra configuration's efficient utilization of space, four different combinations of six crucibles, up to forty-two permutations of two-metal combinations, are available for co-deposition in a single vacuum pumpdown.

The Hydra eliminates adjacent source interactions without complex beam directions and bulky field shunting components. Thus, the design allows close source proximity for uniform coating and material interaction. Additionally, individual water cooling for each source prevents steam build-up and the inclusion of separate sweep coils for each source and promotes the total independence of the operation parameters of each source from the adjacent source.
