TI - Multi-Species Child-Langmuir Law with Application to ECR Ion Sources J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - We generalize the classical single-species Child-Langmuir Law to analyze multi-species beams from ECR ion sources. The formulation assumes the relative weight of each species in the extracted beam is known. We apply the results to charge state distribution data from Artemis- and Venus-type sources at the NSCL and LBNL respectively. The total measured beam current is close to the maximum current predicted by the multi-species Child Langmuir law in each case, which indicates that beam extraction occurs close to space-charge-limited flow conditions. Prospects for application of the results and further studies on the topic are outlined.
