First Claim
Patent Images
1. Apparatus for redirecting a particle beam from an initial direction lying along an initial axis, to a final direction lying in a plane which intersects said axis, said final direction being other than radially away from said axis, said apparatus comprising:
- a first redirection structure for redirecting said beam from said initial direction to an intermediate direction lying in said plane, anda second redirection structure for redirecting said beam within said plane from said intermediate direction to said final direction.

Abstract
A beam is redirected from an initial direction lying along an initial axis to a final direction lying in a plane which intersects the initial axis (the final direction being other than radially away from the axis) by first redirecting the beam from the initial direction to an intermediate direction lying in the plane, and then redirecting the beam within the plane from the intermediate direction to the final direction.

24. A method for redirecting a particle beam from an initial direction lying along an initial axis, to a final direction lying in a plane which intersects said axis, said final direction being other than radially away from said axis, said method comprising redirecting said beam from said initial direction to an intermediate direction lying in said plane, and redirecting said beam within said plane from said intermediate direction to said final direction.

25. A gantry for redirecting a particle beam from a fixed source to any one of a range of paths each of which is aimed at an object of interest, said paths all lying in a common plane intersecting said object, said gantry comprising:
-
first means for bending said beam to lie in said plane in a direction not aimed at said object, second means for bending said beam within said plane to cause said beam to be aimed at said object, and means for rotating said second bending means about said object to cause said beam aimed at said object to traverse said range of paths.
