Abstract The ESRF storage ring is going to be upgraded into an Extremely Bright Source(EBS). The orbit correction system of the EBS ring will require 320 BPMs and 288 correctors instead of 224 BPMs and 96 correctors for the present ring. On the new ring, we are planning to reuse 192 Libera Brilliance electronics and 96 fast correctors power supplies and the 8 FPGA controllers of the present system and to add 128 new BPMs electronics and 196 new correctors power supplies. These new BPM electronics and power supplies will not have the fast 10 KHz data broadcast capability of the components of the present system. So we plan to implement an hybrid slow/ fast correction scheme on the SR of the EBS in order to reuse the present fast orbit correction system on a reduced set of the BPMs and correctors and combine this fast orbit correction with an orbit correction performed at a slower rate using the full set of BPMs and correctors. We have made simulations to predict the efficiency of this scheme for the EBS and tested on the present ring a similar orbit correction scheme using only 160 BPMs and 64 correctors for the fast corrections . We present the results of our simulations and experiments.
