Abstract (en)
[origin: ES8101324A1] The electrodes of an electron-gun system of a color-picture tube are heated less as their distance from the cathode of the system increases. The electrode materials are so chosen with respect to their coefficients of expansion that no mechanical stresses are caused in the system structure despite the different temperatures.
