Abstract
A cavity for use in an accelerator is formed by an inner wall comprised of at least two different materials. According to embodiments of the present invention, a portion of the structure forming the inner wall of the cavity may be comprised of a first material (e.g., copper) while another portion forming the inner wall of the cavity may be comprised of a second material (e.g., steel). Using different materials for different portions of the inner walls forming a cavity may cause different Q-factors for the cavity while the shape of the cavity remains constant.
Claims27
An apparatus for an accelerator, comprising an inner wall forming a cavity that has an input aperture and an output aperture, wherein said inner wall includes a first portion that includes a first material and a second portion that includes a second material.
An apparatus for an accelerator, comprising a cavity formed, at least in part, by a first inner wall portion and a second inner wall portion, wherein said first inner wall portion comprises a first material, said second inner wall portion comprises a second material and said second inner wall portion forms an end plate.
An apparatus for use with an accelerator, comprising a plurality of cavities, wherein at least one of said plurality of cavities has a first inner wall portion and a second inner wall portion, wherein said first inner wall portion comprises copper and said second inner wall portion comprises steel.
An apparatus for use with an accelerator, comprising:
- a portion of a first metallic material;
- and
- a portion of a second metallic material coupled to said portion of a first metallic material to form a cavity having an input aperture and an output aperture.
A method for establishing the Q-factor of a cavity for an accelerator, comprising:
- constructing a cavity having a first inner wall portion and a second inner wall portion, wherein said first inner wall portion includes a first material and said second inner wall portion includes a second material that is different from said first material.
A method for determining a configuration of a cavity for an accelerator, comprising:
- determining an internal geometry for a cavity that produces a desired electron acceleration within said cavity when electrons are introduced into said cavity;
- determining a desired Q-factor for said cavity;
- and
- determining a position of a portion of a first material and a position of a portion of a second material for forming said cavity such that said cavity has said desired Q-factor and said internal geometry.
A computer program product in a computer readable medium for identifying configuration of a cavity for an accelerator, comprising:
- first instructions for identifying an internal geometry for a cavity that produces a desired electron acceleration within said cavity when electrons are introduced into said cavity;
- second instructions for identifying a desired Q-factor for said cavity;
- and
- third instructions for identifying a position of a portion of a first material and a position of a portion of a second material for forming said cavity such that said cavity has said desired Q-factor and said internal geometry.
