摘要： Methods are described wherein the signals from various sensors that monitor parameters such as beam position, beam intensity at each turn, number of turns, extracted current, extracted beam profile in space and energy are used to determine the effect of the variation of different parameters that control the operation of an accelerator. The diagnostic measurements and adjustments may be based upon measuring and evaluating parameters as a function of turn, and are part of an automated feedback loop for achieving the proper automated operation. The methods can be used to establish proper operating values for the accelerator parameters for optimum beam operation. By the use of feedback the operation of the accelerator can be automatically controlled in real time.

摘要： The transmission of photons through a target produces “holes” in the transmitted energy spectrum that are characteristic of the NRF energies of the nuclear isotopes in the target. Measuring the absorption via the transmission of these photons through a target allows the production of tomographic images that are associated with specific nuclear isotopes. Thus three-dimensional density patterns are generated for the elements in a container. The process is very much like standard X-ray tomography but it identifies specific nuclear isotopes as well as their densities.

摘要： Methods and apparatus are described wherein a charged beam in an enclosed conducting cavity in an accelerator is monitored for position, current, and energy. One method uses induced electric signals on non-intercepting conducting electrodes. Another method uses an intercepting and moving electrode than can be moved into the beam to different degrees to monitor the beam current and vertical profile at different radial positions. Non-intercepting electrodes are also used as part of a moving diagnostic probe to monitor properties of the beam at different radial positions. Another method uses the current in the leads to a power supply, a portion of this current being equal to the beam current. Another method uses the magnetic and electric fields from the beam that penetrates a non-conducting portion of the conducting cavity. Yet another method uses the radiation emitted during acceleration of the beam by the deflecting magnets that guide the beam.

摘要： Disclosed herein are methods and systems of scanning a target for potential threats using the energy spectra of photons scattered from the target to determine the spatial distributions of average atomic number and/or mass in the target. An exemplary method comprises: illuminating each of a plurality of voxels of the target with a photon beam; determining an incident flux upon each voxel; measuring the energy spectrum of photons scattered from the voxel; determining, using the energy spectrum, the average atomic number in the voxel; and determining the mass in the voxel using the incident flux, the average atomic number of the material in the voxel, the energy spectrum, and a scattering kernel corresponding to the voxel. An exemplary system may use threat detection heuristics to determine whether to trigger further action based upon the average atomic number and/or mass of the voxels.

摘要： A compact circular magnetic induction accelerator (betatron) for use as a borehole gamma ray source includes a field magnet and generally circular pole pieces composed of a class of ferrite having the general formula M.sup.2+ Fe.sub.2.sup.3+ O.sub.4, where M represents two or more divalent metal ions from the group consisting of Mn, Zn and Ni. The core magnet is in the form of two symmetrical closed loops, with one leg of each loop passing axially through the circular pole pieces. The field coil and the core coil may be arranged in series or in parallel, and switching circuits are provided for effecting electron beam capture and ejection. In an illustrative borehole application, the betatron is used as a gamma ray source in a bulk density logging tool.
