Title (EN) RADIATION EMISSION DEVICE
(FR) DISPOSITIF D’ÉMISSION DE RAYONNEMENT
Abstract:
(EN) A radiation emission device (100,200,800) is provided. The radiation emission device (100,200,800) may include a cathode (126) configured to emit an electron beam and an anode (122,230) configured to rotate on a shaft (112,220). The anode (122,230) may be situated to receive the electron beam from the cathode (126). The radiation emission device (100,200,800) may further include a rotor (120) configured to drive the anode (122,230) to rotate. The rotor (120) may be mechanically connected to the shaft (112,220). The radiation emission device (100,200,800) may further include a sleeve (110,236,812) configured to support the shaft (112,220) via at least one bearing (114,234). The cathode (126), the anode (122,230), and the rotor (120) may be enclosed in an enclosure (124,810) that is connected to the sleeve (110,236,812). At least a portion of the sleeve (110,236,812) may reside outside the enclosure (124,810).
(FR) L’invention porte sur un dispositif d’émission de rayonnement (100,200,800). Le dispositif d’émission de rayonnement (100,200,800) pourra comporter une cathode (126) configurée pour émettre un faisceau d’électrons et une anode (122,230) configurée pour tourner sur un arbre (112,220). L’anode (122,230) pourra être placée de manière à recevoir le faisceau d’électrons issu de la cathode (126). Le dispositif d’émission de rayonnement (100,200,800) pourra comporter en outre un rotor (120) configuré pour faire tourner l’anode (122,230). Le rotor (120) pourra être relié mécaniquement à l’arbre (112,220). Le dispositif d’émission de rayonnement (100,200,800) pourra comporter en outre un manchon (110,236,812) configuré pour porter l’arbre (112,220) par l’intermédiaire d’au moins un palier (114,234). La cathode (126), l’anode (122,230) et le rotor (120) pourront être confinés dans une enveloppe (124,810) reliée au manchon (110,236,812). Au moins une partie du manchon (110,236,812) pourra résider en dehors de l’enveloppe (124,810).
