The detection of evaporation residues produced with low-intensity radioactive ion beams requires detection systems with efficiency close to 100%. In this perspective the set-up in LNL employed for fusion measurements has been upgraded by using a new ionization chamber, which ensures a high count rate particle identification for fusion studies involving low-intensity exotic beams. The new detector reduces the response time by adopting a series of tilted electrodes so that it can withstand rates up to hundreds of kHz. A first test with stable beams has been performed successfully and further tests are programmed to optimize the performances.
