Device and method for irradiating objects with electron beam

Irradiation device for irradiating objects with electron beams, the irradiation device comprises

• at least one electron beam emitter having an electron exit window,
• at least one sensor device for detecting a first dose control parameter of the electron beam,
• wherein,
• the electron beam emitter is adapted to move past the sensor device such that the electron beam emitted from the electron exit window passes within a sensing area of the sensor device, and the sensor device comprises more than one conductor each having a conductor surface in the sensing area of the sensor device, which conductor surface is adapted to be exposed to electrons of the electron beam.

Method for irradiating objects with an electron beam, the method comprising:

• moving at least one electron beam emitter, which emits an electron beam through an electron exit window of the at least one electron beam emitter, past at least one sensor device, which detects a first dose control parameter of the electron beam;
• the at least one electron beam emitter being moved past the at least one sensor device such that the electron beam emitted from the electron exit window passes within a sensing area of the at least one sensor device;
• and
• exposing, to the electron beam, a conductor surface of at least one conductor of the at least one sensor device.
