Abstract (en)

The collector (22) in a linear-beam electron tube is insulated from its heat sink (32) so that it can be operated at a depressed potential. The insulation comprises two bands (24,40) of dielectric sequentially in contact between the collector (22) and heat sink (32). The intervening space (44) is sealed off and preferably filled with a dielectric fluid to improve heat transfer and inhibit voltage breakdown. Gaps in one band (24) are preferably aligned with solid parts of the other to reduce electric leakage.
