| Number | Title | Issue Date |
| 7151266 | Nuclear cargo detector Apparatus for the inspection of cargo containers for nuclear materials comprising one or more arrays of modules comprising grounded, closed conductive tubes filled with an ionizing gas mixture such as, but not limited to, Argon:CO2. A wire is suspended al... | 12/19/2006 |
| 7057390 | Linear beam raster magnet driver based on H-bridge technique An improved raster magnet driver for a linear particle beam is based on an H-bridge technique. Four branches of power HEXFETs form a two-by-two switch. Switching the HEXFETs in a predetermined order and at the right frequency produces a triangular current waveform. ... | 06/06/2006 |
| 7002147 | Highly sensitive vacuum ion pump current measurement system A vacuum system comprising: 1) an ion pump; 2) power supply; 3) a high voltage DC—DC converter drawing power from the power supply and powering the vacuum pump; 4) a feedback network comprising an ammeter circuit including an operational amplifier and a series of ... | 02/21/2006 |
| 6986585 | Radius of curvature controlled mirror A controlled radius of curvature mirror assembly comprising: a distortable mirror having a reflective surface and a rear surface; and in descending order from the rear surface; a counter-distortion plate; a flow diverter having a flow diverter aperture at the center... | 01/17/2006 |
| 6956218 | Compaction managed mirror bend achromat A method for controlling the momentum compaction in a beam of charged particles. The method includes a compaction-managed mirror bend achromat (CMMBA) that provides a beamline design that retains the large momentum acceptance of a conventional mirror bend achromat. ... | 10/18/2005 |
| 6943964 | Single element laser beam shaper A single lens laser beam shaper for converting laser beams from any spatial profile to a flat-top or uniform spatial profile. The laser beam shaper includes a lens having two aspheric surfaces. The beam shaper significantly simplifies the overall structure in compar... | 09/13/2005 |
| 6904957 | Cooled particle accelerator target A novel particle beam target comprising: a rotating target disc mounted on a retainer and thermally coupled to a first array of spaced-apart parallel plate fins that extend radially inwardly from the retainer and mesh without physical contact with a second array of ... | 06/14/2005 |
| 6885008 | Achromatic recirculated chicane with fixed geometry and independently variable path length and momentum compaction A particle beam recirculated chicane geometry that, through the inducement of a pair of 180 degree bends directed by the poles of a pair of controllable magnetic fields allows for variation of dipole position, return loop radii and steering/focussing, thereby allowi... | 04/26/2005 |
| 6740859 | Fractional substraction resistive readout for position sensitive photo-multiplier tubes A readout circuit for an imaging detector that improves resolution and increases field of view in a display compared to traditional readout circuits. The readout circuit comprises two or more amplifiers that receive a row or column of outputs from the imaging detect... | 05/25/2004 |
| 6737655 | Passive, achromatic, nearly isochronous bending system A particle beam bending system having a geometry that applies active bending only beyond the chord of the orbit for any momentum component. Using this bending configuration, all momentum components emerge dispersed in position only; all trajectories are parallel by ... | 05/18/2004 |
