Re: Rejuvenating Magic eye Valves?
I wondered about how long it would take to get up to temperature, too, given that it can only really be heated by radiation.
If the hypothesis about the degradation of the target being due to ion damage is true, then heating the target using its own dissipation will indeed be counter-productive: more current presumably means more ions. The key difference with the types with the phosphor on the glass is that the phosphor is then remote from the target, so is less likely to be bombarded with slow, heavy ions.
The DM70 is directly-heated - I wonder if that makes any difference?
I would like to find a means of heating the target of a Y63 or similar by infra-red, to get it nice and hot without bombardment, and see if that makes matters better or worse!
