Since 1997, there have been two ECR ion sources for producing intense proton beam developed at Institute of Modern Physics (IMP). In 1999, a high current 2.45 GHz ECR proton source for Lanzhou university neutron generator, was constructed and tested at IMP. A mixed ion (H¹⁺ + H²⁺ + H³⁺) beam current of 110 mA with CW mode was delivered from a single aperture of 6mm diameter with microwave power of 600 W at the extraction voltage of 22 kV. Recently a new pulsed proton source has been designed and built at IMP for the CPHS (Compact Pulse Hadron Source) facility in Tsinghua University. Now this source is under commissioning for 60 mA proton beam with 50 keV energy. The long time running stability and beam emittance have been tested and the results are well up to the requirements of CPHS. In this paper, after a short review of the proton ion source for Lanzhou University, the design and test results of the CPHS proton source as well as the LEBT will be presented. The design of the proton ion source and the LEBT for the Chinese ADS project will also be discussed in the contents.

All permanent magnet ECR ion sources have many advantages over traditional ECR ion sources composed of several axial room temperature solenoids and one permanent magnet hexapole magnet, which make them the first choice for many heavy ion facilities and platforms. At IMP, three types of all permanent magnet ECR ion sources have been built for different applications, i.e. the very compact ECR ion source LAPECR1 for intense mono or multi charge state ion beam production, the LAPECR2 ion source installed on the 320 kV high voltage multidisciplinary platform, and the LAPECR3 ion source dedicated to C⁵⁺ beam production for the cancer therapy facility. In this paper, after a general discussion of the ion sources' design, the applications and the operation status of the IMP all permanent magnet ECR ion sources will be presented.
