  Co­her­ent elec­tron cool­ing (CEC) has a po­ten­tial to sig­nif­i­cantly boost lu­mi­nos­ity of high-en­ergy, high-in­ten­sity hadron-hadron and elec­tron-hadron col­lid­ers [1]. In a CEC sys­tem, a hadron beam in­ter­acts with a cool­ing elec­tron beam. A per­tur­ba­tion of the elec­tron den­sity caused by ions is am­pli­fied and fed back to the ions to re­duce the en­ergy spread and the emit­tance of the ion beam. To demon­strate the fea­si­bil­ity of CEC we pro­pose a proof-of-prin­ci­ple ex­per­i­ment at RHIC using one of JLab’s SRF cryo-mod­ules. In this paper, we de­scribe the ex­per­i­men­tal setup for CeC in­stalled into one of RHIC's in­ter­ac­tion re­gions. We pre­sent re­sults of an­a­lyt­i­cal es­ti­mates and re­sults of ini­tial sim­u­la­tions of cool­ing a gold-ion beam at 40 GeV/u en­ergy via CeC.
