Accompanying research includes beam delivery for Flash irradiation, thus it became necessary to set up a fast and reliable beam chopper. The new beam chopper can deliver much shorter pulses than needed for Flash irradiation, minimum pulse widths down to 70ns at 1kV amplitude can be delivered. A short description of the design and installation process, which occurred in 2020, and the experiences of the first 2 years of operation with the new fast beam chopper system is presented.
