Stephen John Brookes has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Photomultiplier apparatus and radiation detector incorporating such apparatus
    Patent number: 9377538
    Abstract: A radiation detection apparatus (2) is disclosed. The apparatus includes a housing (20), a window (26) at least partially transparent to electromagnetic radiation in a first wavelength range and a photomultiplier tube (24) for generating an electrical output signal dependent on the intensity of the electromagnetic radiation. A resiliently deformable optical coupling (28) is located between the window and the photomultiplier tube for allowing at least some electromagnetic radiation passing through the window to enter the photomultiplier tube, and a scintillator element 8 converts gamma radiation into visible light in the first wavelength range entering the photomultiplier tube.
    Type: Grant
