Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
An ion beam source comprising a vacuum tight enclosure, means for generating ions in the enclosure, means for ejecting the ions from the enclosure in a rectangular section beam from an extraction slit, attachment means for attaching the enclosure in vacuum tight communication with an enclosed beam passageway so as to permit limited movement of the enclosure relative to the passageway and thereby provide for adjustment of the relative inclination of the ejected ion beam to the passageway, and constraining means for constraining the enclosure, in its said limited movement, to follow a pivotal motion about either of two perpendicular intersecting axes, one of which is parallel with the said extraction slit and coincident with the origin or apparent origin of the ion beam.
Claim 2
Dependent Claim
124 words
An ion beam source comprising a vacuum tight enclosure, means for generating ions in the enclosure, means for ejecting the ions from the enclosure in a rectangular section beam from an extraction slit, attachment means for attaching the enclosure in vacuum tight communication with an enclosed beam passageway so as to permit limited movement of the enclosure relative to the passageway and thereby provide for adjustment of the relative inclination of the ejected ion beam to the passageway, and constraining means for constraining the enclosure, in its said limited movement, to follow a pivotal motion about either of two perpendicular intersecting axes, one of which is parallel with the said extraction slit and coincident with the origin or apparent origin of the ion beam.
Claim 3
Dependent Claim
22 words
An ion beam source as claimed in claim 1, wherein the enclosure is attached to the beam passageway through a vacuum bellows.
Claim 4
Dependent Claim
20 words
An ion beam source as claimed in claim 1, wherein the said constraining means comprise spherically machined relatively slidable surfaces.
Claim 5
Dependent Claim
22 words
An ion beam source as claimed in claim 1, wherein the said constraining means comprise gimbals upon which the enclosure is mounted.
