AbstractResults from 4-gap Resistive Plate Chambers (RPCs) under irradiation by fully stripped relativistic ions (normalized momentum p/M = gamma beta = 2.7, atomic charge Z = 1-6) are presented. A time resolution of 80 ps at high efficiency has been obtained by using standard 'off the shelf' 4-gap timing RPCs from the new HADES time-of-flight wall. The resolution worsened to 100 ps for similar to 1 kHz/cm(2) proton flux and for similar to 100 Hz/cm(2) carbon flux. The chambers were operated at a field E = 100 kV/cm, showing a high stability during the measurements. It seems to exist ample room for improvement, in particular regarding the time resolution.
