Abstract A Low En­ergy RHIC elec­tron Cooler (LEReC) is presently under con­struc­tion at BNL to im­prove the lu­mi­nos­ity of the Rel­a­tivis­tic Heavy Ion Col­lider (RHIC). The re­quired elec­tron beam will be pro­vided by a pho­toe­mis­sion elec­tron gun and ac­cel­er­ated by a RF lin­ear ac­cel­er­a­tor. As a re­sult, LEReC will be first bunched beam elec­tron cooler. In ad­di­tion, this will be the first elec­tron cooler to cool beams under col­li­sions. The achieve­ment of very tight elec­tron beam pa­ra­me­ters re­quired for cool­ing is very chal­leng­ing and is being ad­dressed by a proper beam trans­port and en­gi­neer­ing de­sign. In this paper, we de­scribe ac­cel­er­a­tor physics re­quire­ments, de­sign con­sid­er­a­tions and pa­ra­me­ters, as well as as­so­ci­ated chal­lenges of such elec­tron cool­ing ap­proach.
