Electron Beam Irradiation Applications

The irradiation of materials with electron beams or X rays is used extensively to enhance or modify their physical, chemical or biological properties. These electron beam “irradiators” cover a very wide range of accelerators technology, beam current and energies to produce a wide variety of products, mostly with polymers. They also are used for curing ink, coatings, and adhesives as well as for...

Emission characteristics of photoconductive antennas based on low-temperature-grown GaAs and semi-insulating GaAs.

Terahertz radiation was generated with several designs of photoconductive antennas (three dipoles, a bow tie, and a coplanar strip line) fabricated on low-temperature-grown (LT) GaAs and semi-insulating (SI) GaAs, and the emission properties of the photoconductive antennas were compared with each other. The radiation spectrum of each antenna was characterized with the photoconductive sampling t...

Intraoperatic electron beam irradiation in pancreatic cancer.

Intraoperative electron beam radiation therapy (IOERT) is a technique in which a single high fraction radiation treatment is administered at the time of surgery. Using IOERT, the total radiation dose delivered to a tumor can be increased since sensitive normal tissues are removed from the radiation field during the surgical procedure. Furthermore, while the biologic effectiveness of this single...
