  To produce the requested 10 mA proton beam for the China Initiative Accelerator Driven Sub-critical reactor Linac (CI-ADS), electron cyclotron resonance (ECR) ion sources operating at 2.45 GHz have been developed. The CI-ADS proton source developed at IMP can produced stable 35 keV/10 mA continuous wave (cw) beam at the RFQ entrance. The proton beam extracted by a 3-electrode extraction system passes through a low energy beam transport system (LEBT), which is composed of identical solenoids, into the 3.2 MeV radio-frequency quadrupole (RFQ). In order to ensure superconducting cavities commissioning and protection, an electrostatic-chopper has been designed and installed in the LEBT line that can chop the cw beam into a pulsed one. The achieved fall/rise time of the chopper is less than 20 ns. In this paper, the performance of the proton source and the LEBT, such as beam reliability, emittance and beam current tuning will be presented.

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.
