[en] The achievements and future developments of the CPS accelerator complex (50 MeV linac, 800 MeV booster synchrotron (PSB) and 25 GeV Proton synchrotron (PS)) are reported. Evolution of accelerator performance is given. Studies to define performance limitations are presented PSB as injector to the PS supplies 1.8-2.0x10¹³ protons per pulse. To supply the SPS, the ''Continuous Transfer'' extraction system was developed. The pulse-to-pulse programming of many parameters has been brought into routine operation. High-linear density bunches containing 10¹² protons per bunch are obtained for antiproton production at 26 GeV/c to be followed by ''cooling'' and p anti p collisions in the SPS. Studies have started on production and extraction of 20 short bunches with an intensity of 7x10¹² protons to provide the SPS with a proton beam for electron-proton collisions. Deuterons have been successfully accelerated and supplied to the ISR. This gave a stored beam in the ISR of about 9A. A prototype source to produce fully-stripped ions is under construction. For the future a reduction in cycling time and the introduction of the new linac will provide higher intensity for the SPS
