Re: Bringing up to snuff a Tek 465M


 

The reason I think it is secondary emission and not an optical effect
I see both the outer, constant and abruptly delimited shape, which speaks for the secondary emission, *and* intensity-dependent amplitude and spread of bleeding around the trace, which I see as the scattering/dispersion in the phosphor and aluminium coating. Interesting to discuss this, David! Unfortunately, I think I'll have to stop soon since my observations aren't very sharp at this late hour...
