High quality ion beams are required by IMP cyclotron and atomic physics research, so it is important to research and measure beam emitt ance of ECR ion source. 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.

A new all permanent ECR (Electron Cyclotron Resonance) ion source LAPECR2 (Lanzhou All Permanent ECRIS No. 2) is now under developing in IMP. This source will be used to set up on thc IMP 400 HV (High Voltage) platform. This HV platform aims to deliver high ion beams from low charge state to very high charge state, so the rigorous requirement to this ECRIS is obvious. To satisfy this requirement, the ion source is designed to be a very large one, which has very large volumc plasma chamber, larger ECR length and mirror length, and very strong 3 -dimension magnetic field. The detail parameters, are shown in Table 1 listed below.

The visible light of argon plasma produced by the electron cyclone resonance ion source (ECRIS) with wavelength from 300 to 900 nm has been detected by Spec-pro 500i, a grating spectrometer. A great amount of the character lines were emitted when the arc starting. Most of these lines can be identified and were from argon atom and ions with lower charge states such as 1+, 2+ or 3+. A small fraction of unknown lines was possibly from argon ions with higher charge states which needs to be investigated later. Fig.1 shows part of the results, and the referring lines are compared with the up-to-date data from NIST (the National Institute of Standards and Technology) in Table 1.
