| Popis: | International audience; An anomalous global efficiency of the extracted 1+ beam was discovered at the LPSC charge breeder. It was realized that a fraction of injected 1+ beam propagates through the charge breeder plasma without being captured and ionized. As a result of the further experiments andtheoretical considerations it was realized and confirmed that 1+ beam injected into the chargebreeder plasma can be used as a plasma diagnostics tool. Identification of the uncaptured fractionof the 1+ ions allow, for example, estimating the ion-ion collision mean free path of injected 1+beam and plasma densities as a function of microwave power. The presentation will describein more detail the injected 1+ beam as a diagnostic tool to reveal information about differentplasma parameters. Further more, the prospects to use charge breeder ECRIS to study the effectof gas mixing on the ion confinement time will be discussed. |
