Five dif­fer­ent Ring RF Sys­tems are re­quired for the op­er­a­tion of FAIR (Fa­cil­ity for An­tipro­ton and Ion Re­search). These sys­tems have to op­er­ate at fre­quen­cies be­tween 310 kHz and 3.2 MHz, with gap volt­ages up to 40 kVp and duty cy­cles from 5·10-4 up to cw. All sys­tems will be re­al­ized using in­duc­tively loaded (fer­rite or mag­netic alloy) cav­i­ties dri­ven by tetrode-based am­pli­fiers fed by switch-mode power sup­plies. To sta­bi­lize the am­pli­tude, res­o­nance fre­quency and phase, ver­sa­tile dig­i­tal feed­back and feed­for­ward con­trol will be used. This con­tri­bu­tion will pre­sent the lat­est de­vel­op­ment on the power part and the LLRF of the four RF sys­tems of the SIS100 (SIS100 Ac­cel­er­a­tion, SIS100 Bunch Com­pres­sion, SIS100 Bar­rier Bucket and SIS100 Lon­gi­tu­di­nal Feed­back) as well as the CR De­buncher sys­tem which is part of the Col­lec­tor Ring. The progress of these sys­tems varies by a large de­gree. This note will give an overview re­gard­ing the sta­tus of the de­sign, pro­cure­ment, re­al­iza­tion, test­ing, op­ti­miza­tion, com­mis­sion­ing and prepa­ra­tion for in­stal­la­tion of these RF sys­tems.
