	Funding: Work supported by CAS (QYZDB-SSW-JSC025), MOST (contract No. 2014CB845500), and NSF (contract No. 11221064). An all permanent magnet Electron Cyclotron Reso-nance ion source-LAPECR1U (Lanzhou All Permanent magnet ECR ion source no.1 Upgraded), has been built at IMP in 2017 to satisfy the requirements of LEAF (Low Energy intense-highly-charged ion Accelerator Facility) for first two years commissioning. LAPECR1U was designed to be operated at 14.5 GHz to produce intense low and medium charge state ion beams. LAPECR1U features a compact structure, small size, and low cost. A cone-shape iron yoke in injection side and an iron plasma electrode in extraction side were used to enhance the axial magnetic field strength. The typical parameters and the preliminary beam results of the source are given in this paper.

	The ion beams extracted from an Electron Cyclotron Resonance (ECR) ion source always exist strong transverse coupling effect that is caused by the field of the axis mirror magnets and the extraction solenoid. A Pepper Pot probe was developed and used to obtain the full four-dimensional phase space distribution of the low energy beam extracted from the ECR ion source at IMP. This paper describes the design of the Pepper Pot, the setup configuration, the detailed image processing procedure, especially the analysis results verification compared to another type emittance meter. The first four-dimensional emittance is also determined through the Pepper Pot probe. The transverse phase space distribution measurement data of oxygen beams from the LECR4 experimental platform are presented and discussed.

The ion beams extracted from an Electron Cyclotron Resonance (ECR) ion source always exist strong transverse coupling effect that is caused by the field of the axis mirror magnets and the extraction solenoid. A Pepper Pot probe was developed and used to obtain the full four-dimensional phase space distribution of the low energy beam extracted from the ECR ion source at IMP. This paper describes the design of the Pepper Pot, the setup configuration, the detailed image processing procedure, especially the analysis results verification compared to another type emittance meter. The first four-dimensional emittance is also determined through the Pepper Pot probe. The transverse phase space distribution measurement data of oxygen beams from the LECR4 experimental platform are presented and discussed.
