An electronic system includes an external jacket; a wall of an internal cavity that is to be cooled; at least one fixed connection fixing the external wall of the internal cavity that is to be cooled to the external jacket; a heat-transport fluid cooling circuit comprising grooves on the external surface of the wall of the internal cavity and a sleeve comprising a flexible portion positioned flush with the external surface of the external wall of the internal cavity, thereby forming mini-canals with said grooves; a radial extension of the wall of the internal cavity creating connecting points intended to hold the sleeve in place; and a space between the external jacket and the sleeve at the flexible portion of the sleeve.

An annular cathode for a vacuum tube includes a central cylindrical support whose axis is that of the cathode; an outer peripheral electron emitter with annular section whose axis is that of the cathode, extending over the outer perimeter of the cathode; and a folded skirt, secured at an inner end to the central support, and secured, at its outer end, to a plurality of lugs; each lug being disposed in series with the folded skirt, and secured with the folded skirt and with the inner surface of the electron emitter.
