The tank is 7.1 m long, equipped with movable tuners and movable post couplers. The purpose of this DTL model is to verify the RF design choices (in particular on the first 2 tanks where the Post coupler distribution is irregular) as well as implement and debug algorithms and procedure for stabilization and tuning. The preparatory simulation work and the results of measurements campaign are here presented.
