  Co­her­ent elec­tron cool­ing (CEC) is con­sid­ered to be on of po­ten­tial can­di­dates ca­pa­ble of cool­ing high-en­er­gy, high-in­ten­si­ty hadron beams to very small emit­tances. It also has a po­ten­tial to sig­nif­i­cant­ly boost lu­mi­nos­i­ty of high-en­er­gy hadron-hadron and elec­tron-hadron col­lid­ers. In a CEC sys­tem, a per­tur­ba­tion of the elec­tron den­si­ty caused by a hadron is am­pli­fied and fed back to the hadrons to re­duce the en­er­gy spread and the emit­tance of the beam. Fol­low­ing the fund­ing de­ci­sion by DoE of­fice of Nu­cle­ar Physics, we are de­sign­ing and build­ing co­her­ent elec­tron cool­er for a proof-of-prin­ci­ple ex­per­i­ment at RHIC to cool 40 GeV heavy ion beam. In this paper, we de­scribe the lay­out of the CeC in­stalled into IP2 in­ter­ac­tion re­gion at RHIC. We pre­sent the de­sign of the CeC cool­er and re­sults of pre­lim­i­nary sim­u­la­tions.
