摘要： PROBLEM TO BE SOLVED: To provide a system and a method for limiting emittance growth in an electron beam. SOLUTION: This system (10) includes an emitter element (26) configured to generate the electron beam (28) and an extraction electrode (20) positioned adjacent to the emitter element (26) to extract the electron beam (28) out therefrom. The extraction electrode (20) includes an opening (24) therethrough. This system (10) also includes a meshed grid (32) disposed in the opening (24) of the extraction electrode (20) to enhance intensity and uniformity of an electric field at a surface of the emitter element (26) and an emittance compensation electrode (ECE) (34) positioned adjacent to the meshed grid (32) on the opposite side of the emitter element (26) side of the meshed grid (32) and configured to control emittance growth of the electron beam (28).

摘要： PROBLEM TO BE SOLVED: To make a design of an insulator for an X-ray tube or an electron tube as a module type which has durability to high-voltage instability and insulator surface flashover and is compact for an advanced application and is easy for repairs and enables additional power supply routes to the inside and a passage of a coolant.
SOLUTION: A modular insulator assembly for the X-ray tube includes an annular insulator having a cylindrical perimeter wall made of an electrically insulating material. A wall member extends beyond the cylindrical perimeter wall by fixedly mounting on the cylindrical perimeter wall. A first shielding body is arranged by neighboring the wall member, and has an end extending by neighboring a corner section formed by the wall member and the insulator.
