摘要： A remotely controllable sublimation apparatus that includes a crucible block adapted to retain a crucible containing a solid mixture comprising one or more radionuclides, a first heating block comprising one or more first heating elements configured to selectively generate heat having a first temperature sufficient to at least partially sublime the solid mixture, and a collection vessel coupled to the first heating block. The crucible block is movable, relative to the first heating block, between an open position and a closed positon. When the crucible block is in the closed position, the one or more first heating elements are configured to heat the crucible block to the first temperature, thereby heating the solid mixture and producing a vapor that is collected by the collection vessel and leaving a solid residue in the crucible that substantially consists only of the one or more radionuclides.

摘要： The invention provides a system for containing irradiated particles, the system having a housing having a closed upstream end and an open downstream end; an axially disposed tunnel extending from the downstream end to the upstream end, wherein longitudinally extending regions of the tunnel define a plurality of threaded surfaces; a sample cup positioned within the tunnel and proximal to the closed upstream end; threaded plugs matingly received by the threaded surfaces so as to provide at least one seal between the sample cup and the atmosphere external of the housing; and a plurality of deformable substrates disposed between the plugs.

摘要： A converter for generating photons from an electron beam is provided. The converter may include a plurality of converter plates (i) positioned perpendicular to an axis and (ii) arranged sequentially in a direction along the axis from a first converter plate of the plurality of converter plates to a last converter plate of the plurality of converter plates. The first converter plate may be configured to receive an electron beam traveling in the direction along the axis. Further, the first converter plate may have a thickness smaller than a thickness of the last converter plate, wherein a thickness of a particular converter plate is measured along the axis.
