  The ESRF 352 MHz Radio Fre­quency (RF) sys­tem has been up­graded and tai­lored to the new 4th Gen­er­a­tion Ex­tremely Bril­liant Source EBS, that was in­stalled in 2019 and com­mis­sioned in 2020. The five for­mer five-cell cav­i­ties were re­placed with 13 sin­gle cell strongly HOM damped cav­i­ties that were de­vel­oped in house, 10 of which are pow­ered from ex­ist­ing 1 MW kly­stron trans­mit­ters. The re­main­ing three cav­i­ties are in­di­vid­u­ally fed by three 150 kW solid state am­pli­fiers. All this re­quired a re­con­struc­tion in record time of an elab­o­rate WR2300 wave­guide net­work. The low level RF sys­tem as well as the cav­ity and trans­mit­ter con­trol sys­tem have been re­built. The RF de­sign, com­mis­sion­ing and op­er­a­tion ex­pe­ri­ence will be re­ported, in­clud­ing plans for a 4th har­monic RF sys­tem for bunch length­en­ing to fur­ther im­prove the per­for­mance of the new EBS ring.
