TI - LECR5 Development and Status Report 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 - LECR5 (Lanzhou Electron Cyclotron Resonance ion source No. 5) is an 18 GHz room temperature ECR ion source featuring Ø80 mm ID (Internal Diameter) plasma chamber and high magnetic fields. It has been successfully constructed at IMP recently and has been fully commissioned to meet the requirements of SESRI (Space Environment Simulation and Research Infrastructure) project. According to the test results, LECR5 can meet the requirements of SESRI with sufficient beam intensities within the required the transverse emittances. As LECR5 is designed to be optimal for the operation at 18 GHz, we have managed to explore the source performance at 18 GHz with a maximum microwave power around 2 kW. Recent source test indicates, LECR5 can produce not only high intensity ion beams such as 2.12 emA O⁶⁺, 121 e’A of Ar¹⁴⁺, 73 e’A of Kr²³⁺, 145 e’A of Xe²⁷⁺, but also very high charge state ion beams such as 22 e’A of Bi⁴¹⁺. This paper will present the recent progress with LECR5, especially the intense ion beam production and the beam quality investigation.
