Abstract
The current disclosure is related to a downhole tool that comprises an electronic photon generator and at least one detector. The electronic photon generator comprises a cathode configured to emit electrons, a first target configured to generate photons when struck by the electrons, a second target configured to generate photons when struck by the electrons, and a beam steering device that directs the electrons to a first or second target. The at least one detector is configured to detect at least some of the photons emitted by the first target and at least some of the photons emitted by the second target.

A downhole tool, comprising:
- an electronic photon generator comprising:
- a cathode configured to emit electrons;
- a first target configured to generate photons when struck by the electrons;
- a second target configured to generate photons when struck by the electrons;
- a beam steering device to direct the electrons to a first or second target;
- and
- at least one detector configured to detect at least some of the photons emitted by the first target and at least some of the photons emitted by the second target.
An electronic photon generator, comprising:
- a cathode configured to emit electrons;
- a first target configured to generate photons when struck by the electrons;
- a second target configured to generate photons when struck by the electrons.
A method, comprising:
- lowering a downhole tool into a wellbore penetrating a subterranean formation, said downhole tool comprises:
- an electronic photon generator comprising:
- a cathode configured to emit electrons;
- a first target configured to generate photons when struck by the electrons;
- a second target configured to generate photons when struck by the electrons;
- a beam steering device configured to direct the electrons to a first or second target;
- and
- a detector configured to detect at least some of the photons emitted by the first target and at least some of the photons emitted by the second target;
- directing photons emitted by the first target out of the downhole tool at a first location;
- directing photons emitted by the second target out of the downhole tool at a second location;
- and
- determining a property of the downhole tool, the wellbore or the subterranean formation based on signals detected from the photons emitted by the first and second targets.
