Abstract: We have been developing Drabkin energy filters for pulse shaping and energy analysis at the J-PARC spallation neutron source. By installing two Drabkin energy filters in sequence (a double Drabkin filter), subsidiary peaks of the resonant spin-flip are suppressed and pulse shaping could be performed more effectively. In this contribution, simulation results of pulse shaping by a double Drabkin filter for the J-PARC moderators are presented.
