High voltage cascade

A high voltage cascade comprising:

• input terminals configured to receive an input voltage for the high voltage cascade;
• output terminals configured to emit an output voltage;
• and
• a number of cascade half stages, the cascade half stages having respective stage inputs and respective stage outputs, and having a respective capacitor circuit and a respective diode circuit between the respective stage inputs and the respective stage outputs, wherein
• stage inputs of a first cascade half stage are connected to the input terminals,
• a stage output of a last cascade half stage is connected to one of the output terminals,
• stage outputs of each respective cascade half stage are connected to stage inputs of a respective next cascade half stage, so that the cascade half stages form an electrical sequence of cascade half stages,
• the respective diode circuit of each cascade half stage is arranged on a separate first additional circuit board of the high voltage cascade, which is connected electrically and mechanically to a main board of the high voltage cascade,
• the separate first additional circuit boards are oriented orthogonally to the main board and are arranged corresponding to the electrical sequence of the cascade half stages, viewed in a direction of extension, following on sequentially from one another,
• the separate first additional circuit boards are oriented essentially orthogonally to the direction of extension, and
• the respective capacitor circuits of the cascade half stages are arranged to a side next to the separate first additional circuit boards on the main board and are arranged corresponding to the electrical sequence of the cascade half stages and alternating on sides of the separate first additional circuit boards.
