Claim of US Patent No. 9,186,645

1. A system for treating and strengthening a material comprising a surface, said system comprising:
a mobile unit;
at least one electron gun that emits a beam of electrons;
at least one electron accelerator integrated with the mobile unit and positioned to accelerate the beam of electrons; and
at least one beam extraction device comprising a scan coil that emits the accelerated beam of electrons, the at least one
beam extraction device positioned on said mobile unit to irradiate the surface of and treat in-situ, the material located
proximate to said mobile unit, wherein irradiation of said material by the beam of electrons results in in-situ cross-linking
of said material and therefore a strengthening and increased durability of said material.
