Abstract
An x-ray target assembly including a housing having a recess, a cooling fluid contained within the recess and an x-ray target attached to the housing, wherein the x-ray target does not directly contact the cooling fluid.
Claims45
An x-ray target assembly, comprising:
- a housing having a recess;
- a cooling fluid contained within said recess;
- an x-ray target attached to said housing, wherein said x-ray target does not directly contact said cooling fluid.
An x-ray generator comprising:
- a particle source that accelerates particles;
- and
- an x-ray target assembly comprising:
- a housing having a recess;
- a cooling fluid contained within said recess;
- an x-ray target attached to said housing, wherein said x-ray target does not directly contact said cooling fluid and said particles strike said x-ray target so that x-rays are emitted from said x-ray target.
3 more elements
An x-ray target assembly, comprising:
- a housing having a recess;
- an x-ray target attached to said housing;
- a cooling fluid contained within said recess, wherein said cooling fluid is sealed within said recess via a joint not susceptible to galvanic corrosion.
An x-ray generator comprising:
- a particle source that accelerates particles;
- and
- an x-ray target assembly comprising:
- a housing having a recess;
- an x-ray target attached to said housing, wherein said particles strike said x-ray target so that x-rays are emitted from said x-ray target;
- and
- a cooling fluid contained within said recess, wherein said cooling fluid is sealed within said recess via a joint not susceptible to galvanic corrosion.
4 more elements
A joint assembly comprising:
- a first piece made of a first material;
- a second piece made of a second material that is different than said first material, where said first piece is separated from said second piece by a gap;
- and
- a high quality electron beam weld joint formed between said first piece and said second piece within said gap.
1 more element
A method of forming a high quality electron beam joint, comprising:
- positioning a first piece made of a first material from a second piece made of a second material that is different than said first material so that a gap is formed therebetween;
- and
- applying an electron beam to said gap so that a high quality weld joint is formed that is not susceptible to galvanic corrosion.
