A high voltage vacuum feed through (23) for an electron tube (25) has an anode (28) and an insulating body (1) of ceramic material, the insulating body (1) having a continuous hollow space (10). The anode (28) has a rear part (2) and a front part (3) mounted thereto. The rear part (2) consists of a first metallic material, having a thermal expansion coefficient corresponding to a thermal expansion coefficient of the ceramic material. The rear part (2) is arranged in the hollow space (10) of the insulating body (1) and is soldered into the insulating body (1) in a vacuum-tight fashion. The front part (3) has a second metallic material whose heat conductivity is larger than that of the first metallic material. The high voltage vacuum feed through reliably remains vacuum-tight during operation and can be easily provided with different target materials.

An anode target, a ray light source, a computed tomography device, and an imaging method, which relate to the technical field of ray processing. The anode target comprises a first anode target, a second anode target, and a ceramic plate. The first anode target is used for enabling, by means of a first voltage carried on the first anode target, an electron beam emitted by a cathode to generate a first ray on a target spot of the first anode target. The second anode target is used for enabling, by means of a second voltage carried on the second anode target, an electron beam emitted by the cathode to generate a second tray on a target spot of the second anode. The ceramic plate is used for isolating the first anode target from the second anode target. By means of the anode target, the ray light source, the computed tomography device and the imaging method, dual-energy distributed ray imaging data can be provided and the imaging quality of a ray system can be improved.
