The energy spread of electron beam artificially was increased with the help of the detuning system in the electron cooler. The Influence of electron energy detuning on maximum accumulated intensity, the lifetime and stability of ion beam were experimentally investigated with the beam of 3.7MeV/u ¹¹²Sn³⁵⁺ in CSRm. The lifetime was derived from the signals of ion beam intensity from DCCT varying with time, and the instability was observed by mean of the longitudinal frequency signals from Schottky probe. The experiments results show that no significant influence of electron energy detuning on the maximum accumulated intensity and lifetime. Due to the limitation of beam intensity from injector, the space charge limitation and saturation condition was not approached, and the obvious evidence for instability suppression by the detuning has not observed in such detuning frequency range.
