| 1 | A design study on the CSNS LEBT pre-chopper显示文摘The China Spallation Neutron Source (CSNS) front end incorporates a pre-chopper in the Low Energy Beam Transport line (LEBT) that will remove a 530 ns section of beam at approximately 1 MHz rate, which is the RF frequency of the ring at injection. It's one of the most critical devices for properly controlling the injecting beam loss. Physical designing of the pre-chopper is carried out, and the RFQ itself is used as the beam dump of the chopper system. In order to examine the reliability of the pre-chopper design, the beam study of a similar chopper system is successfully performed. The results of physical design and experiments are presented. | LIU HuaChang OUYANG HuaFu PENG Jun HUANG Tao GONG KeYun XU TaoGuang FU ShiNian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 3 |
| 2 | The R&D status of DTL for CSNS显示文摘The China Spallation Neutron Source (CSNS) is a spallation neutron research facility being built at Dongguan in Guangdong Province. The 324 MHz Alvarez-type Drift Tube Linac will be used to accelerate the H- ion beam from 3 to 80.0 MeV with peak current 15 mA. The R&D of a prototype structure at the low energy section of DTL is taking place at IHEP. The first unit tank ~2.8 m in length and 28 drift tubes containing electromagnetic quadrupoles are developed. The SAKAE coils are applied in the fabrication of the electromagnetic quadrupoles. This paper introduces the R&D status of the tank and 28 drift tubes. The fabrication process and measurement results of the electromagnetic quadrupoles of special interest are also presented. | YIN XueJun GONG KeYun PENG Jun SONG Hong XIAO YongChuan LI AHong LIU Lei FU ShiNian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 3 |

| 9 | Research progress on high intensity hadron accelerator in China显示文摘High intensity hadron beam has wide-range important applications.In recent years,several projects with intense-beam hadron accelerator are under design,development or construction in China.We are facing a lot of challenges in beam physics and key technology of the accelerators.Beam loss and beam emittance must be minimized for such a high intensity accelerator.Space charge effect and nonlinear dynamics should be taken into account in beam physics and accelerator design.In this paper we will present the recent research progress in China on beam dynamics,new technology development and beam experiments for intense beam hadron accelerators,including linear accelerator,synchrotron and cyclotron. | FU ShiNian | 2012 | Chinese Science Bulletin2012，57，36： | 0 |

| 13 | Study on the fringe field effect of quadrupoles for CSNS MEBT显示文摘Background Medium energy beam transport(MEBT)of the China Spallation Neutron Source matches the beam from RFQ to DTL.It is found in the beam commissioning that the fringe field effect of quadrupoles in MEBT has a great influence on matching.Purpose The aspect ratio of the quadrupoles is 1.67,which induces a strong fringing field effect,and the hard-edge model used in the design needs to be improved.Methods The slicing model was performed,and the accuracy of the quadrupole model was improved.Furthermore,to use the improved model online,based on the premise that the integral field of the quadrupole magnet remains unchanged,an equivalent transfer matrix was worked out to make the beam parameters consistent with the slicing model in the simulation.Results and conclusions In the machine study,with the new model,the beam parameters at the RFQ exit were measured,which is much closer to the RFQ design value.The MEBT lattice was redesigned based on the equivalent transfer matrix.With the new matched MEBT,the transmission rate of DTL reached 99.5%in the beam commissioning,which is increased by a factor of 3%. | Xibao Luo Jun Peng Shinian Fu Sheng Wang | 2023 | Radiation Detection Technology and Methods2023，7，1： | 0 |
