Abstract :
This paper describes a simple method that substantially improves the production of gated electron bunch trains by totally suppressing undesired background photoemission between the trains. A device has been designed and tested with a drive laser for proof-of-principle demonstration. The predicted functionality and performance are verified on an Energy-Recovery-Linac (ERL) electron accelerator. The method can find applications whenever the laser pulse repetition rate and length need to be tailored.
