Electron focusing systems and techniques integrated with a scintillation detector covered with a reflective coating

摘要

The present disclosure provides systems and methods where an electron focusing device can be combined with a scintillation detector to better focus the electrons generated by a light sensing device. The scintillation detector can include a scintillation crystal that is covered by an inner light-reflecting coating layer where the scintillation crystal may emit photons due to measurement radiation(s). The light sensing device can include a photomultiplier that may receive the photons emitted by the scintillation crystal and convert them into the electrons generated. The electron focusing device can include a metal ring magnet or one or more conducting coils encircling the scintillation crystal that may create a magnetic field so as to focus the electrons generated by the light sensing device.

1. A system, comprising:
a scintillation detector comprising a scintillation crystal covered by an inner coating layer, said inner coating layer being reflective to a light spectrum; a light sensing device capable of converting photons emitted by said scintillation crystal into electrical signals comprising a plurality of electrons; and an electron focusing device comprising at least one conductive unit capable of generating a magnetic field so as to focus at least a portion of said plurality of electrons toward a central axis of the system, such that a first group of the plurality of electrons passing the electron focusing device and leaving the system is more focused towards a central axis of the system than the first group prior to passing the electron focusing device.
