The disclosure relates to very high power (one megawatt and more) electron tubes with cylindrical anodes. To cool the anode, which receives about one kilowatt per square centimeter, water is usually made to circulate in a jacket surrounding the anode with grooves to facilitate ebullition. The invention proposes a structure where the anode wall is drilled in its thickness and throughout its height with very fine and very numerous water circulation conduits. The anode is made in many superimposed sections brazed to one another by their edges. The conduits are formed in the individual sections before this brazing operation. The channels all lead into a structure for the distribution of cooling water which distributes the water uniformly in all the tubes. The anode can thus distribute a flux with power of over 2 kW/cm.sup.2 on a surface area of over 1000 cm.sup.2.
A high power vacuum electron tube with an essentially cylindrical anode, wherein the anode is formed by at least one generally cylindrical section, a cylindrical wall of each of said at least one generally cylindrical section having a plurality of drilled longitudinal conduits symmetrically distributed around each cylindrical section for the circulation of cooling fluid said plurality of conduits extending linearly throughout the height of the section, wherein each of the longitudinal conduits lead, at one end of the anode, into a structure for the distribution of cooling water which is uniformly supplied to each of said plurality of longitudinal conduits that lead into said structure.
