Intense beams extracted from ECR ion source usually have low energy, so it is suitable to use Electric-Sweep Scanner to measure the emittance. This kind of measurement is popularly used at ECR ion source, and it has some prominent merits such as high accuracy, very short time of data processing and easy expressing of the emittance pattern. So we designed and built this emittance scanner to measure emittance of the ion beams produced by LECR3 ion source. The structure of the ESS is shown in Fig.l, and the photo of the ESS is shown in Fig.2.展开更多

In year 2003, according to the arrangements of atomic physics research experiments and the ECR ion source research activities, ion beams of 14 elements were produced on LECR3. The elements include ^16O, ^40At, ^129Xe, ^63Cu, ^65Zn, ^56Fe, ^58Ni, ^26Mg, ^208Pb, ^35C1, ^37C1, ^28Si, ^84Kr and ^181Ta. Many of them were tested for the first time on LECR3 ion source.展开更多

Fig.1 illustrates the design of LECR3. The design of this ion source is based on the IMP 14.5 GHz ECR ion source, which was named LECR2(Lanzhou Electron Cyclotron Resonance ion source No.2). The axial magnetic field is produced by two solenoids and展开更多
