	A 100 MeV/100 kW electron LINAC is being constructed by IHEP, China for the NSC KIPT Neutron Source project in Ukraine. A LLRF system is required to produce the driver RF input of the klystron and maintain the accelerating phase and amplitude stability of the machine. The LLRF system consists of an RF reference distribution system, six identical control units, and the fast RF interlock module. The main part of control unit is the PXI-bus crate implemented with PXI9846 - 4 ADC digitizer board and ICS572 - high speed 2 ADC/2 DAC signal process board. An EPICS IOC based on WinDriver as the PCI device driver is developed and tested. Preliminary results show phase detect resolution of 0.03 degree (rms) of 2856 MHz signal has been achieved. *Mail Address: maxp@ihep.ac.cn

C-ADS Injector-I accelerator is a 10-mA 10-MeV CW proton linac, which uses a 3.2-MeV normal conducting 4-Vane RFQ and superconducting single-spoke cavities for accelerating. The frequency of RFQ accelerator is 325 MHz. The test stand composed of an ECR ion source, LEBT, RFQ, MEBT and beam dump have been installed and the first stage of beam commissioning have been finished at IHEP in 2014 mid-year. At 90% duty factor, we got 11 mA proton beam at RFQ exit with 90% beam transmission efficiency, while 95% beam transmission efficiency at 70% duty factor.

The C-ADS accelerator is a CW (Continuous-Wave) proton linac with 1.5 GeV in beam energy, 10 mA in beam current, and 15 MW in beam power. C-ADS Injector-I accelerator is a 10-mA 10-MeV CW proton linac, which uses a 3.2-MeV normal conducting 4-Vane RFQ and superconducting single-spoke cavities for accelerating. The frequency of RFQ accelerator is 325 MHz. The test stand composed of an ECR ion source, LEBT, RFQ, MEBT and beam dump have been installed and the first stage of beam commissioning have been finished at IHEP in 2014 mid-year. At 90% duty factor, we got 11 mA proton beam at RFQ exit with 90% beam transmission efficiency, while 95% beam transmission efficiency at 70% duty factor. The energy after RFQ was measured by TOF method with FCTs. The transverse emittance measured by double-slits emittance meter was 0.135 π mm-mrad, which of detailed data analysis will be presented in this paper.
