At RHIC, heavy ion beams cross tran­si­tion en­ergy dur­ing ac­cel­er­a­tion to en­er­gies re­quired by the physics pro­grams. In the past, to bat­tle lon­gi­tu­di­nal in­sta­bil­i­ties, a Lan­dau cav­ity was turned on just after ac­cel­er­a­tion through tran­si­tion en­ergy. The Lan­dau cav­ity with mod­i­fied fre­quency will be im­ple­mented be­fore beam crosses tran­si­tion in Run-14. Lon­gi­tu­di­nal dy­nam­ics with this new con­fig­u­ra­tion have been sim­u­lated to op­ti­mize the phase and am­pli­tude of the Lan­dau cav­ity. We will pre­sent sim­u­la­tion re­sults in the re­port.
