Abstract
A system and method for collecting backscattered electrons within a substantially evacuated vessel containing both an electron-emitting cathode assembly and an electron-attracting anode assembly. The system and method comprises an electron collector assembly including a first plate, a second plate, an internal member, a fluid inlet, and a fluid outlet. The first plate is mounted within the vessel closest to the anode assembly. The second plate is mounted within the vessel closest to the cathode assembly. The internal member is positioned between the first plate and the second plate, and includes an internal conduit for conveying a heat absorbing cooling fluid therethrough.
Claims18
An electron collector assembly for collecting backscattered electrons within a substantially evacuated vessel that contains an electron-emitting cathode and an electron-attracting anode spaced apart therein, said electron collector assembly comprising:
- a first plate mounted proximate to said anode within said vessel, said first plate having a first side at least partially facing said anode and a second side facing opposite said first side;
- a second plate mounted proximate to said cathode within said vessel, said second plate having a first side and a second side at least partially facing said cathode;
- an inner member positioned between said first plate and said second plate, said inner member having an internal conduit for conveying a heat absorbing cooling fluid therethrough;
- an inlet in fluid communication with said internal conduit;
- and
- an outlet in fluid communication with said internal conduit;
- wherein the second side of the first plate is substantially conterminous with a first side of the inner member, and the first side of the second plate is substantially conterminous with a second side, opposite the first side of the inner member.
An electron collector assembly for collecting backscattered electrons within a substantially evacuated vessel that contains an electron-emitting cathode and an electron-attracting anode spaced apart therein, said electron collector assembly comprising:
- a first plate mounted proximate to said anode within said vessel, said first plate having a first side at least partially facing said anode and a second side facing opposite said first side;
- an inner member integral with said first plate, said inner member having an internal conduit for conveying a heat absorbing cooling fluid therethrough;
- a second plate mounted proximate to said cathode within said vessel, said second plate having a first side and a second side at least partially facing said cathode;
- an inlet in fluid communication with said internal conduit;
- and
- an outlet in fluid communication with said internal conduit;
- wherein the second side of the first plate is substantially conterminous with a first side of the inner member, and the first side of the second plate is substantially conterminous with a second side, opposite the first side of the inner member.
