Many developments were carried out on these devices to enhance their performances and improve the knowledge on the ECR charge breeding process in laboratories worldwide. At LPSC, recent experiments in pulse mode were carried out to estimate plasma parameters such as the ionisation, charge exchange and confinement times, providing indications on the high charge state ions confinement. A new model of the 1+ beam capture was also proposed and experimentally verified by studying the stopping of injected ions of different masses. Present ECR charge breeder optimum efficiencies vary from 10 to 20% depending on the ion species and the facilities specifications. The total efficiency ranges from 35 to 90% and the charge breeding time from 10 to 25 ms/q. Electron Beam Ion Source (EBIS) is an alternate CB technology with lower contamination yield, yet limited injection flux capability. ECR CB sustains a higher 1+ beam intensity acceptance and its prospects to improve the efficiency, charge breeding time and beam purity are identified.
