Abstract
A detector includes an outer shell having a shell profile in which a welded portion of the shell profile extends as an annular flange in an outward direction relative to a center axis of the outer shell. The detector further includes an end cap positioned adjacent the welded portion of the outer shell. The end cap and the welded portion of the outer shell are welded together to form a seal. A method of making a detector is also provided.
Claims20
A detector including:
- an outer shell having a shell profile in which a welded portion of the shell profile extends as an annular flange in an outward direction relative to a center axis of the outer shell;
- and
- an end cap positioned adjacent the welded portion of the outer shell, the end cap and the welded portion of the outer shell being configured to be welded together to form a seal.
A detector including:
- an outer shell, acting as a cathode, extending along an axis, the outer shell having a shell profile in which a welded portion of the shell profile extends as an annular flange in a radially outward direction relative to the axis;
- an anode extending along the axis within the outer shell;
- and
- an end cap supporting the anode and extending within an end of the outer shell, the end cap including a cap profile that matches the shell profile of the outer shell, wherein the end cap includes a welded annular shoulder that extends radially outward with relative to the axis, and the welded shoulder and the welded portion of the outer shell are adjacent each other and welded together to form a seal.

A method of making a detector, the method including:
- providing an outer shell, acting as a cathode, extending along an axis,
- providing an anode extending along the axis within the outer shell;
- positioning an end cap within an end of the outer shell to support the anode, the end cap including a cap profile in which a shoulder of the end cap extends in a radially outward direction;
- crimping a portion of the outer shell to form a shell profile that matches the cap profile of the end cap, wherein a welded portion of the outer shell extends in a radially outward direction adjacent the shoulder of the end cap;
- and
- welding the welded portion of the outer shell and shoulder of the end cap together from the radially outward direction.
