The Elec­tron-Ion Col­lider (EIC) re­quires crab cav­i­ties to com­pen­sate for a 25 mrad cross­ing angle and achieve max­i­mum lu­mi­nos­ity. The crab cav­ity Radio Fre­quency (RF) sys­tem will in­ject low lev­els of noise to the crab­bing field, gen­er­at­ing trans­verse emit­tance growth and po­ten­tially lim­it­ing lu­mi­nos­ity life­time. In this work, we es­ti­mate the trans­verse emit­tance growth rate as a func­tion of the Crab Cav­ity RF noise and quan­tify RF noise spec­i­fi­ca­tions for rea­son­able per­for­mance. Fi­nally, we eval­u­ate the pos­si­ble mit­i­ga­tion of the RF noise in­duced emit­tance growth via a ded­i­cated feed­back sys­tem.
