Increases in grid perveance through reductions in grid spacings without the attendant tendency toward arcing and shorting between grids at close spacing are shown to be achievable through substitution of higher-perveance dished grids for flat grids. Such dished grids can be spaced more closely than flat grids without exhibiting a propensity for shorting because their thermal warpage characteristics are more uniform and predictable.
