Abstract
A radiation detector device is disclosed that includes a scintillator including a scintillator crystal and a hybrid photodetector (HPD) coupled to the scintillator. The HPD includes an electron tube having an input window and a photocathode adapted to emit photoelectrons when light passing through the input window strikes the photocathode. Further, the hybrid photodetector includes an electron detector adapted to receive photoelectrons emitted by the photocathode. The electron detector comprises a semiconductor material characterized by a bandgap of at least 2.15 eV.

A radiation detector device, comprising:
- a scintillator including a scintillator crystal;
- and
- a hybrid photodetector (HPD) coupled to the scintillator, the HPD including:
- an electron tube having an input window;
- a photocathode adapted to emit photoelectrons when light from the scintillator crystal passes through the input window and strikes the photocathode;
- and
- an electron detector adapted to receive photoelectrons emitted by the photocathode, wherein the electron detector comprises a semiconductor material characterized by a bandgap of at least 2.15 eV,
- wherein the radiation detector device is a well-logging detector device.
A hybrid photodetector, comprising:
- an electron tube having an input window;
- a photocathode adapted to emit photoelectrons when light passing through the input window strikes the photocathode;
- and
- an electron detector adapted to receive photoelectrons emitted by the photocathode, wherein the electron detector comprises a semiconductor material characterized by a bandgap of at least 2.15 eV,
- wherein the hybrid photodetector does not include a dynode.
