Patent number: 10598799Abstract: A method and a device for the directional discrimination of penetrating charged particles uses a one-dimensional transparent dielectric column which is surrounded by a specular reflector. The column is coupled to a photon counter and is enclosed in a light baffle to exclude external photons. Penetrating charged particles passing through the column interact with the column electromagnetically, producing photons which internally reflect down the column and are counted by the photon counter. The penetration depth of the charged particles through the column is deduced from the photon count by application of theoretical means. The resulting penetration depth is geometrically fit within the dimensions of the column, yielding a discrimination of the variance of the charged particle's trajectory from the pointing direction of the column. In an embodiment, a particle's magnetic rigidity is ascertained by photon counting.Type: GrantFiled: December 8, 2016Date of Patent: March 24, 2020Inventor: Joseph Nathaniel Berlin

Patent number: 10578750Abstract: The present invention identifies ? decay and other events included in the emission of an LaBr3 scintillator and only collects ? ray events. An LaBr3 scintillation detector is provided with an LaBr3 scintillator 10, a photomultiplier tube 12, an oscilloscope 14, and a computer 18.
