Some number of years ago, the television transmitter at my station used  2 
Varian Klystrons running in parallel to make 60 Kw output power. The 
collector of these klystrons was surrounded by a large bucket thru which 
large quantities of de-ionized water (DI) flowed for cooling. These 
collectors were made of pure finned copper. I do not remember any problems 
with corrosion or degradation of the collector after years of operation in 
direct contact with DI water.
