TUPAL002	Numerical Calibration of the Injection Bump Sizes During the Beam Commissioning for CSNS	1011
	M.Y. Huang, S. Wang, S.Y. Xu IHEP, Beijing, People's Republic of China
	In order to control the strong space charge effects, which cause large beam loss during the injection and acceleration processes, phase space painting method was used for injecting a small emittance beam from the linac into the large acceptance of the Rapid Cycling Synchrotron (RCS). During the beam commissioning, in order to control and optimize the painting results, the positions and ranges of the horizontal and vertical painting should be adjusted accurately. Therefore, the numerical calibration of the injection bump sizes was very important and need to be done as soon as possible. In this paper, a method to calibrate the horizontal and vertical bump sizes was presented and applied to China Spallation Neutron Source (CSNS). The numerical calibration results would be given and discussed.

	M.Y. Huang, H.C. Liu, S. Wang, Zh.H. Xu, P. Zhu IHEP, Beijing, People's Republic of China X.H. Lu CSNS, Guangdong Province, People's Republic of China
	In order to inject the H⁻ beam to the Rapid Cycling Synchrotron (RCS) with high precision and high transport efficiency, the injection beam parameters need to be measured and then corrected while its eccentric position or direction angle is too large. In this paper, firstly, a method to measure the injection beam parameters by using two of the four multi-wire scanners (MWSs) is presented. The injection commissioning results confirmed that this method works well. Secondly, a method to measure the signals of injection beam and circular beam by the INMWS02 is presented and the method work well during the beam commissioning.

TUPAL005	Study on the Fixed Point Injection during the Beam Commissioning for CSNS	1017
	M.Y. Huang, H.C. Liu, S. Wang, S.Y. Xu IHEP, Beijing, People's Republic of China
	In order to inject the H⁻ beam into the Rapid Cycling Synchrotron (RCS) of China Spallation Neutron Source (CSNS) accurately, different injection methods were used in different periods of beam commissioning for CSNS. In the early stage of beam commissioning, since the precise relative position of the injection beam and circular beam was unknown and the injection beam power was relatively small, the fixed point injection method was used. In this paper, the fixed point injection method is studied in detail and the beam commissioning results are given and discussed. In addition, a method to adjust the timing of the injection pulse power is presented and confirmed by the beam commissioning.
