Dipole field kicks arisen from the construction and alignment of the magnets may cause the orbit distortion and reduce the efficiency of beam extraction and striking target in RTBT transport line of CSNS. In this paper, orbit correction is done based on XAL Orbit Correction application with the algorithm modified partially and the result was according with by AT toolbox. Meanwhile, the orbit correction before the target was special considered for the beams striking the target center vertically.

Rapid Cycling Synchrotron (RCS) of the China Spallation Neutron Source (CSNS) is a high intensity proton accelerator, with average beam power of 100kW. In order to high intensity beam operation, the beam coupling impedance of the extracted kickers must be controlled. Longitudinal and transverse impedance of extracted kicker prototype with power supply had been roughly measured by coaxial-wire and dual-wire methods respectively. At the same time, impedance of window has been analyzed theoretically and simulated based on CST PARTICLE STUDIO.

The bunch length of electron storage ring of BEPCII was measured repeatedly during steady synchronous mode and streak camera was calibrated well. From the bench lengthening , the coupling impedance of the whole ring was estimated, which was according with theoretic impedance budget . Meanwhile, the small ap optics for improving the luminosity was feasible in collision mode form synchronous result .

The linac of the China Spallation Neutron Source(CSNS) will be commissioned from October 2013. The linac will be commissioned in three phases. The delivery of beam to the RCS is planned for October 2015. This paper describes the commissioning plans for the MEBT and DTL parts of the linac. Techniques for finding the RF set-point, matching and steering are presented, as well as codes to assist in the beam commissioning.
