The LEBT chop­per is a crit­i­cal el­e­ment of the SNS ac­cel­er­a­tor sys­tem. In this work, the ben­e­fit of in­creas­ing the chop­ping volt­age am­pli­tude for the pre­sent chop­ping pat­tern is shown with beam sim­u­la­tions, and an on­go­ing hard­ware up­grade of the chop­per pulser units is dis­cussed. In ad­di­tion, with the prospect of higher volt­age ca­pa­bil­ity of the new pulser de­sign, two al­ter­na­tive chop­ping pat­terns which re­duce the switch­ing fre­quency of the chop­per pulsers down to 1/2 or 1/4 of the pre­sent chop­ping pat­tern, are also ex­plored with beam sim­u­la­tions.
