    摘要： The invention comprises an apparatus and method of use thereof for extracting ions from an ion source, such as for use in cancer treatment or tomographic imaging. The extraction apparatus uses a triode extraction system, with the ion source and/or first electrode held at a first potential; an extraction electrode held at a second potential; and a gating electrode, positioned between the ion source and the extraction electrode, oscillating and/or alternating between a first suppression potential proximate that of the ion source potential and a second extraction potential between the ion source potential and the extraction electrode potential. Optionally, the ion source comprises an electron cyclotron resonance ion source.

    摘要： A scintillation material is longitudinally packaged in a circumferentially surrounding sheath, where the sheath has a lower index of refraction than the scintillation material, to form a scintillation optic or scintillation fiber optic. The scintillation material yields secondary photons upon passage of a charged particle beam, such as a positively charged residual particle beam having transmitted through a sample. The internally generated secondary photons within the sheath are guided to a detector element by the difference in index of refraction. Multiple scintillation optics are assembled to form a two-dimensional scintillation array coupled to a two-dimensional detector array, such as for use in determination of state of the residual charged particle beam, determination of an exit point of the particle beam from the sample, path of the treatment beam, and/or tomographic imaging.

    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.
