    摘要： The invention comprises a method or apparatus for tomographically imaging a sample, such as a tumor of a patient, using positively charged particles. Position, energy, and/or vectors of the positively charged particles are determined using a plurality of scintillators, such as layers of chemically distinct scintillators where each chemically distinct scintillator emits photons of differing wavelengths upon energy transfer from the positively charged particles. Knowledge of position of a given scintillator type and a color of the emitted photon from the scintillator type allows a determination of residual energy of the charged particle energy in a scintillator detector. Optionally, a two-dimensional detector array additionally yields x/y-plane information, coupled with the z-axis energy information, about state of the positively charged particles. State of the positively charged particles as a function of relative sample/particle beam rotation is used in tomographic reconstruction of an image of the sample or the tumor.

    摘要： The invention comprises a method and apparatus for generating a rare earth from a rare earth oxide, comprising the sequential steps of: (1) reducing temperature about the rare earth oxide to less than zero degrees Celsius; (2) reducing pressure to boil off contaminant water in a powder sample of the rare earth oxide at a molecular escape velocity not disturbing the powdered rare earth oxide; and (3) heating the rare earth oxide to greater than 1000° C. in the presence hydrogen gas while optionally: (1) collecting and determining mass of a water product to determine a consumption mass of the starting hydrogen gas in a main reaction process using the equation RE2O3+3H2→2RE+3 H2O, wherein “RE” comprises at a rare earth and (2) injecting replacement hydrogen gas into the main reaction chamber up to the consumption mass.
