摘要： Concentrating particles in a turbulent gas flow may include receiving, in a receptacle, a turbulent gas flow that includes particles. The concentration of particles in a gas flow exiting the receptacle at a first port is increased as compared with a concentration of the particles in the gas flow received by the receptacle. The increased concentration of particles is accomplished by removing a portion of the gas flow by using a second port, and fluidly communicating the gas flow through a tube in the receptacle. The tube has a smaller diameter at the end of the tube at which the gas flow exits the tube than diameter at the end of the tube at which the gas flow is received.

摘要： A property of a treatment beam is controlled during a scanning period. A portion of a region is exposed to an imaging x-ray beam during a scanning period, the imaging x-ray beam being generated by an electron-beam scanner. X-ray radiation from the region is detected, the x-ray radiation representing an attenuation of the imaging x-ray beam caused by the portion of the region. A first image of the portion of the region is generated based on the detected x-ray radiation. A characteristic of the portion of the region is determined from the generated first image. An input derived from the characteristic is generated, the input configured to cause a source of a treatment beam to modify a property of the treatment beam. The source of the treatment beam modifies a property of the treatment beam during the scanning period by providing the input to the source of the treatment beam.

摘要： A method for operating an inspection system is disclosed in which an item under inspection may be moved between radiation sources and detectors illuminated by the sources. The radiation sources may be positioned such that radiation from at least some of the sources impinge on the radiation detectors, forming acute angles with respect to a plane having a normal direction coinciding with the first direction that are substantially in excess of three degrees. Data accumulated by the radiation detectors may be processed to form a three-dimensional tomographic data image of at least a portion of the item under inspection. The processing may be performed using an algebraic reconstruction technique using an inverse system matrix. The inverse matrix can be derived without first computing a transpose of the system matrix.

摘要： A method for operating an inspection system is disclosed in which an item under inspection may be moved in a first direction relative to and at least partially between at least one radiation source and at least some radiation detectors illuminated by the at least one radiation source. The radiation source and detectors may be operated such that ray paths extending linearly between the at least one radiation source and at least some of the radiation detectors form acute angles with respect to a plane having a normal direction coinciding with the first direction that are substantially in excess of three degrees. Data accumulated by the radiation detectors may be processed to form a three-dimensional tomographic data image of at least a portion of the item under inspection. In some embodiments, transmission data based upon outputs of a plurality of radiation detectors may be processed to form a tomographic image, in which, for all possible orientations of a three dimensional plane, the orientation vectors of at least some of the rays of radiation for which transmission data was accumulated and used to form the tomographic image form an angle of less than eighty-five degrees or greater than ninety five degrees with respect to the plane.
