Eh, no ;-) But it's called grid 4. Grid 3 however has the same potential
as the anode.

Well,
apparently only in Great Britain since in Germany, we call that
'screen grid', too. Only the final anode is called anode.
Waht, even in CRTs? In the UK, the electrodes of a pentode -- a signal
ampiifying valve are :
cathode, control grid, screen grid, supressor grid, anode.
Yes, the same here.
But for a CRT they're cathode, (control) grid,
first anod, second (or
focus) anode, somethimes third anode and final anode.
Or, as we say, cathode, grid 1 (or Wehnelt), grid 2 (or screen grid), grid
3, grid 4 and anode.
All other
electrodes in a normal tube besides the cathode are called
'control grid' (or just grid), 'screen grid', 'supressor grid'
and so on.
Are you seriously saying that in Germany, the focus electrode in a CRT is
called a 'supressor grid'?
