Abstract
A spectroscopy device including: an electron source arranged to emit a flux of electrons towards a sample, a pulsed photon source emitting photon pulses towards the sample, at least one spectrometer for receiving a flux of electrons originating from the sample, at least one electron detector; and at least one deflector, between the electron source and the at least one electron detector, synchronized with the pulsed photon source to allow or prevent the passage of electrons emitted by the electron source, towards the electron detector.
Claims13
A spectroscopy device, comprising:
- an electron source arranged to emit a flux of electrons towards a sample;
- a pulsed photon source emitting photon pulses towards said sample;
- at least one spectrometer for energetically dispersing a flux of electrons originating from the sample;
- at least one electron detector;
- at least one deflector between the electron source and the at least one electron detector, synchronized with said pulsed photon source to allow the passage of electrons emitted by said electron source towards said at least one electron detector in an open state of the at least one deflector and prevent the passage of electrons emitted by said electron source, towards said at least one electron detector in a closed state of the at least one deflector;
- and
- synchronization electronics arranged to synchronize the at least one deflector with the photon source, wherein the synchronization electronics are configured to send command signals to place the at least one deflector in the open state and in the closed state.
