摘要： An apparatus and method for the production of radioisotopes utilizing an energy recovery linac. The ERL system is composed of an electron beam source, multiple superconducting radio frequency cavities operating at 4.5 K, a thin radiator, a target material, and a beam dump. The accompanying method discloses the use of the ERL system to generate desired radioisotopes via target interaction with bremsstrahlung photons while allowing recovery of a substantial portion of the electron beam energy before the beam is extracted to the beam dump.

摘要： A universal mounting adapter is configured for interchangeably mounting a calibration source to two or more different imaging devices. The two imaging devices have different mounting brackets so they cannot be used with the same conventional calibration source. The present adapter includes mounting mechanisms for both types of bracket, allowing the attached calibration source to be moved from one imaging device to the other, while maintaining the calibration source in a prescribed geometry within the respective imaging device. This can be performed without the need for any tools.

摘要： A high efficiency electro-optic dendrimer based technology for nanophotonic integrated circuit devices is presented. In particular, a high power terahertz (THz) source is implemented using an electro-optic dendrimer via electro-optic rectification. Electro-optic rectification provides inherent power scalability, because, pump-THz conversion is not limited either by emission saturation or by heat dissipation. Low dielectric loss and high electro-optic coefficient of dendrimer along with a waveguide structure provides higher output power and tunable THz power generation. A dendrimer fiber array is also disclosed by means of which the input/output signals are connected to multiple components and devices.

摘要： Methods and apparatus for detecting variations in electromagnetic fields, in particular, terahertz (THz) electromagnetic fields, are provided. The methods and apparatus employ polarization detection devices and controllers to maintain or vary the polarization of modulated signals as desired. The methods and apparatus are provided to characterize electromagnetic fields by directing the electromagnetic field and a probe beam upon an electro-crystal and detecting the modulation of the resulting probe beam. Detection of the modulation of the probe beam is practiced by detecting and comparing the polarization components of the modulated probe beam. Aspects of the invention may be used to analyze or detect explosives, explosive related compounds, and pharmaceuticals, among other substances. A compact apparatus, modular optical devices for use with the apparatus, sample holders, and radiation source mounts are also disclosed.

摘要： An acoustic crystal structure includes defect cavities that concentrate the driving pressure from applied sound waves into the cavities to cavitate gas bubbles in a liquid to produce sonoluminescence. This device may be used to study sonoluminescence or cavitation or to perform sonochemistry, nuclear fusion etc. in the cavities. A waveguide may be operatively coupled to the acoustic crystal to extract, collect and route a band of electromagnetic (EM) radiation around a specified source wavelength to an output port for emission by an antenna to provide an EM source. The waveguide may, for example, be a photonic crystal defect waveguide, a photonic crystal optical fiber or Sommerfeld waveguide. The marriage of the sonoluminescence phenomena with an acoustic crystal and embedded waveguide provides for an efficient source of narrow or broad band IR or THz radiation
