Abstract
A method and apparatus are disclosed for generating X-rays employing a vacuum tube containing a cathode and an anode. A heat conducting member is connected to the anode. Equal amounts of heat are transmitted from different locations alone the length of the heat conducting member to an extended cooling surface remote from the anode, and the extended cooling surface is cooled.
Claims5
In apparatus for generating high intensity radiation having an evacuated housing, means for directing an electron beam from a cathode within said housing for impingement on different parts of an anode within said housing, the improvement comprising:
- means for conducting heat from said anode through an elongate conductor;
- means for transferring substantially equal amounts of heat from different locations along the length of said elongate conductor to a cooling surface, and
- means for directing a cooling fluid over said cooling surface to cool said surface and thus said anode.
In a method of generating X-rays by directing an electron beam from a cathode onto different parts of an anode within a housing, with the anode connected to an anode heat conductor the improvement comprising:
- transferring substantially equal amounts of heat from different locations along the length of said anode heat conductor to an extended cooling surface remote from said anode to produce a substantially uniform temperature over said cooling surface, and
- cooling said extended cooling surface to cool said anode.
Apparatus for generating high intensity radiation comprising:
- an evacuated housing,
- means for directing an electron beam from a cathode for impingement on an anode inside said housing,
- means for conducting heat from said anode through an elongate conductor,
- means for transferring substantially equal amounts of heat from different locations along the length of said elongate conductor to a cooling surface, and
- means for directing a cooling fluid over said cooling surface to cool said cooling surface and thus said anode.
The method of generating x-rays comprising the steps of:
- directing an electron beam from a cathode onto an anode,
- conducting heat from said anode to an anode heat conductor,
- providing relative movement between said electron beam and said anode,
- transferring substantially equal amounts of heat from different locations along the length of said anode heat conductor to an extended cooling surface remote from said anode to produce a substantially uniform temperature over said cooling surface, and
- cooling said extended cooling surface to cool said anode.
