Device for determining e.g. dose rate of electron beam emitted by electron accelerator of sterilization system for sterilizing object, has processing unit whose reconstruction unit reconstructs penetration curve for predefined energy beam

摘要

The device has an absorption unit (8) for partial absorption of electrons emitted between first and second chambers (2, 4), and another absorption unit (10) for partial absorption of the electrons emitted between the second chamber and a third chamber (6), The chambers provide measurements of current according to an electron beam (F) crossing the chambers. A processing unit processes the provided measurements to determine a dose rate of the electron beam and comprises a reconstruction unit for reconstructing a penetration curve for a predefined energy beam. Independent claims are also included for the following: (1) a sterilization system (2) a method for determining energy and dose rate of an electron beam emitted by an electron accelerator.
