Beam bending snout for mobile electron accelerators
A method and system for in situ cross-linking of polymers, Bitumen, and other materials to produce arbitrary functional or ornamental three-dimensional features using electron beams provided by mobile accelerators comprises defining a desired pattern for imparting on a target area, mapping the target area, defining at least one discrete voxel in the target area according to the desired pattern to be imparted on the target area, assigning an irradiation value to each of the at least one discrete voxels, and delivering a dose of irradiation to each of the at least one discrete voxels according to the assigned irradiation value.
1. A beam bending snout comprising:
a beam transport tube;
a second beam tube connected to the beam transport tube;
a rotatable vacuum seal connecting the beam transport tube and second beam tube;
a first bending magnet configured in the rotatable vacuum seal configured to direct a beam in the beam transport tube into the second beam tube; and
a second bending magnet configured to bend the beam toward a desired surface.
2. The beam bending snout of claim 1 further comprising:
a particle accelerator configured to generate the beam.
3. The beam bending snout of claim 1 wherein the beam comprises an electron beam.
4. The beam bending snout of claim 1 further comprising:
a target configured at an end of the second beam tube, the target comprising a material that converts the beam into a different particle beam.
5. The beam bending snout of claim 1 wherein the beam transport tube is substantially vertically oriented in relation to the desired surface.
6. The beam bending snout of claim 1 further comprising:
a beam window configured at an end of the second beam tube, wherein a vacuum is maintained within the beam bending snout.
7. The beam bending snout of claim 6 wherein the second beam tube further comprises:
a bend between the rotatable vacuum seal connecting the beam transport tube and second beam tube, and the beam window.
8. The beam bending snout of claim 1 further comprising:
a mechanical drive configured to rotate the second beam tube about an axis defined by the beam.
9. The beam bending snout of claim 8 wherein the mechanical drive comprises a motor.
10. The beam bending snout of claim 8 wherein the mechanical drive can rotate the second beam tube in a sweep comprising 360 degrees about the axis defined by the beam such that the beam is incident with the desired surface along a beam arc.
11. The beam bending snout of claim 10 further comprising:
a control system configured to control the mechanical drive.
