    摘要： The invention comprises a method and apparatus for using a multi-layer multi-color scintillation based detector element to image a tumor of a patient using a process of determining residual energies of positively charged particles after passing through the patient, the process comprising the steps of: (1) transmitting the positively charged particles at known energies through the patient and into a multi-layer detector element; (2) detecting first and second secondary photons, resultant from passage of the positively charged particles, respectively from a first layer of a first scintillation material and a second layer of a second scintillation material at two respective layer depths, where the first wavelength range differs from the second wavelength range; (4) determining residual energies of the positively charged particles, using output from the step of detecting; and (5) relating the residual energies to body densities to generate an image.

    摘要： The invention comprises a method and apparatus for imaging a tumor of a patient using one or more imaging systems positionable about the tumor and treating the tumor using positively charged particles, such as: (1) using a rotatable gantry support to support and rotate a section of a positively charged particle beam transport line about a rotation axis and a tumor of a patient; (2) using a rotatable and optionally extendable secondary support to support, circumferentially position, and laterally position a primary and optional secondary imaging system about the tumor; (3) image the tumor using the primary and optional secondary imaging system as a function of rotation and/or translation of the secondary support; and (4) treat, optionally concurrently with imaging, the tumor using the positively charged particles as a function of circumferential position of the section of the charged particle beam about the tumor.

    摘要： A Faraday cup structure for use with a processing tool. The cup structure has a conductive strike plate coupled to a circuit for monitoring ions striking the strike plate to obtain an indication of the ion beam current. The electrically conductive strike plate is fronted by a mask for dividing an ion beam intercepting cross section into regions or segments. The mask including walls extending to the strike plate for impeding ions reaching the sensor and particles dislodged from the sensor from entering into the evacuated region of the processing tool.

    摘要： The invention comprises a method and apparatus for increasing fuel efficiency of a vehicle moving through air, comprising the steps of: carrying, by the vehicle, a tail cone in an undeployed state; deploying the tail cone on a back of the vehicle while the vehicle is in motion, the tail cone comprising a flexible material; and pressurizing, with the air, an interior space at least partially enclosed by the tail cone, the tail cone forming an aerodynamic feature extending at least fifteen inches behind the vehicle, where pressurizing transforms the tail cone from a flexible material to a static and compliant aerodynamic feature, which increases miles per gallon of the vehicle by at least ten percent at speeds in excess of fifty miles an hour through a reduction in drag force on the vehicle.
