	Funding: work supported by NSFC. Grand No. 2014CB845503 A window-type RFQ is designed and fabricated by Peking University for the key technique research of Beijing Isotope-Separation-On-Line neutron-rich beam facility(BISOL) . It is planed to accelerate 50mA deuteron CW beam to 1MeV. The 60kV intervene voltage is designed to decrease the risk of high voltage discharge since the RFQ works in CW mode. High power test shows that the intervane voltage is over 60kV when the cavity power consumption is 48kW. The beam experiment was done and 1.8mA CW beam was obtained at the exit of RFQ with over 90% transmission efficiency. It is the first time that window-type RFQ is used to accelerate light ion with high frequency(>100MHz). The experiment result shows that the window-type structure have great advantages in CW working mode.

	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.
