  A high intensity ECR proton source with 14 GHz microwave heating was successfully developed at IMP. The idea of the working mechanism and the structure of the proton source, as well as using 14 GHz microwave heating, were first proposed in the world. The experimental platform was set up and preliminary commissioning was performed. The experimental results indicate that the source can produce a total of 4 mA CW hydrogen beams with microwave power of 200 W and extraction voltage of 40 kV, in which H2+ and H3+ are included. The successful commissioning of the proton source demonstrates that the proposed mechanism and the structure are feasible.

For a new injector linac project launched at IMP, a superconducting ECR ion source SECRAL II is now under construction. This ion source is a duplicated one of SECRAL I which is operated routinely for HIRFL facility at the frequency of 18-24 GHz. SECRAL II is designed to be operated at the frequency of 28 GHz, which needs slightly higher radial field at the plasma chamber wall. The fabrication of the cold mass was started at early 2013, and it has been completed in May 2014. The engineering design of the whole superconducting magnet has also been finished and ready for fabrication. After a brief introduction of the recent results obtained with SECRAL I ion source, this paper will present the cold mass test results and the cryogenic system design of SECRAL II magnet. The test bench design will be also discussed.
