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.

Beam bending snout for mobile electron accelerators

Infrastructure-scale additive manufacturing using mobile electron accelerators

A system, method, and apparatus for wellbore inspection comprise an electron accelerator to generate X-rays, a rotating collimator assembly configured to produce a cone of X-rays, and at least one detector assembly configured to collect backscattered X-rays. A position assembly can be provided to move the electron accelerator, rotating collimator assembly, and detector through a wellbore. A computer system is configured to receive data from the detector and generate an image of the wellbore.

High-energy X-ray source and detector for wellbore inspection

An accelerator comprising at least one accelerator cavity, an electron gun, at least one cavity cooler configured to at least partially encircle the accelerator cavity, a cooling connector, an intermediate conduction layer formed between the at least one cavity cooler and the at least one accelerator cavity configured to facilitate thermal conductivity between the cavity cooler and the accelerator cavity, a mechanical support connected to the accelerator cavity via at least one endplate and configured for stabilizing the accelerator cavity, and a refrigeration source for providing refrigerant via the cooling connector to the at least one cavity cooler.

Compact SRF based accelerator

A conduction cooling system for linear accelerator cavities. The system conducts heat from the cavities to a refrigeration unit using at least one cavity cooler interconnected with a cooling connector. The cavity cooler and cooling connector are both made from solid material having a very high thermal conductivity of approximately 1&#xd7;10W mKat temperatures of approximately 4 degrees K. This allows for very simple and effective conduction of waste heat from the linear accelerator cavities to the cavity cooler, along the cooling connector, and thence to the refrigeration unit.

Conduction cooling systems for linear accelerator cavities

A method and system for treating and strengthening material filling a pothole. One or more electron accelerators can be integrated with a mobile unit. The electron accelerators are positioned on the mobile unit to heat, irradiate and treat in-situ, both the base material and a material filling a pothole located proximate to the mobile unit, wherein irradiation of the material by the electron accelerators results in in-situ cross-linking or polymerization of the material and therefore a strengthening and increased durability of the material filling the pothole. Deep heating of the substrate allows pothole repair even under extreme low temperature winter conditions. The in-situ treatment of the material filling the pothole in a road surface to toughens and strengthens the road surface and the filled pothole which results in improved material properties of the surface, enhanced durability, and improved lifetime of the pothole fill.

A method and system for treating and strengthening material. One or more electron accelerators can be integrated with a mobile unit. The electron accelerators are positioned on the mobile unit to irradiate and treat in-situ, a material located proximate to the mobile unit, wherein irradiation of the material by the electron accelerators results in in-situ cross-linking or polymerization of the material and therefore a strengthening and increased durability of the material. The in-situ treatment of a road surface to toughen and strengthen the road surface constructed with standard asphalt construction can result in improved material properties of the surface, enhanced durability, and improved lifetime.
