  A Low Energy intense-highly-charged ion Accelerator Facility (LEAF), which is mainly consist of an 45 GHz superconducting ECR ion source, LEBT and an 81.25 MHz 4-vane RFQ, was designed to produce and accelerate heavy ions, from helium to uranium with A/Q between 2 and 7, to the energy of 0.5 MeV/u. The typical beam intensity is designed up to 2 emA CW for the uranium beam. The project was launched in 2015 and has been successfully commissioned with He+ (A/Q=4), N2+ (A/Q=7) beam and accelerated the beams in the CW regime to the designed energy of 0.5 MeV/u. Beam commissioning results of He+ beam have been reported previously. This paper presents the details of N2+ commissioning and beam studies.

  China Accelerator Driven Subcritical System (C-ADS) program was launched in China in 2011, which aims to design and build an ADS demonstration facility with the capability of more than 10 MW thermal power in multiple phases lasting about 20 years. In the first phase, a demo linac has been constructed and commissioned successfully to demonstrate the key technologies of the high-power CW mode superconducting linac. Followed the China ADS roadmap, a superconducting driver linac with 500MeV and 5mA proton beam is designed for the second phase of China Initiative Accelerator Driven Subcritical System (CiADS) program. The commissioning results of the China ADS 25 MeV demo linac and the RAMI oriented beam physics design of CiADS linac are presented in this paper.

  An 81.25 MHz continuous wave (CW) radio frequency quadrupole (RFQ) accelerator has been developed and fabricated for the Low Energy Accelerator Facility (LEAF) by the Institute of Modern Physics (IMP) of the Chinese Academy of Science (CAS). The operation frequency is 81.25 MHz and the inter-vane voltage is a constant of 70 kV. It took about 44 hours continuous conditioning to reach RF power of 75 kW which is 1.1 time of the maximum designed operation power, and the CW operation of He+ beam and N2+ beam had successfully accelerated to the designed energy of 0.5 MeV/u. Both the results of the high power test and the beam test will be presented in this paper.
