Calabazas Creek Research is nearing completion of an Atomic Layer Deposition system to mitigate corrosion in copper cooling channel in RF sources and similar devices. The system applies a thin ceramic coating over all internal surfaces to separate the metal structure from the coolant fluid, effectively eliminating corrosion. The technology has been extensively tested, including accelerated life testing.
The photograph shows the prototype system nearing completion. First operation is scheduled for the end of August with installation into a traveling wave tube factory in September. This development is funded by the U.S. Navy.
