  A new beam dump has been de­signed, which with­stands the fu­ture pro­ton beam ex­tracted from the PS Booster at CERN, con­sist­ing of up to 1014 pro­tons per pulse at 2 GeV after its up­grade in 2018/2019. In order to be able to ef­fi­ciently re­lease the de­posited heat, the new dump will be made out of a sin­gle cylin­dri­cal block of a cop­per alloy and be cooled by forced ven­ti­la­tion. In order to de­ter­mine the en­ergy den­sity dis­tri­b­u­tion de­posited by the beam in the dump, Monte Carlo sim­u­la­tions were per­formed using FLUKA, and thermo-me­chan­i­cal analy­ses car­ried out by im­port­ing the en­ergy den­sity into Ansys. In ad­di­tion, CFD sim­u­la­tions of the air­flow were car­ried out in order to ac­cu­rately es­ti­mate the heat trans­fer con­vec­tion co­ef­fi­cient on the sur­face of the dump. In this paper we de­scribe the de­sign process and high­light the con­straints of in­te­grat­ing a new dump for in­creased beam power into the ex­ist­ing fa­cil­ity.
