Call for Proposal

Date: 2019-06-01

The China Spallation Neutron Source (CSNS) offers neutron scattering to all qualified users. The proposals of beamtime application for the first round of CSNS in 2018 have been fully reviewed and the results of the review have been sent to all applicants. The proposal round of CSNS in the second half of 2019 is from Sep. 26th 2019 to Jan. 16th, 2020, welcome users at home and abroad to submit applications online. All proposals will be critically reviewed for scientific merit by experts.

 

The deadline for this proposal round is Jun. 30th, 2019 (At 0’clock on Dec.12th the CSNS User Service System will close the application channel).

 

For this proposal round:

 

Applicants must submit proposal through the CSNS User Service System (http://user.csns.ihep.ac.cn/). And you must have an account to submit the proposal. The application background (purpose, significance, current status at home and abroad), experimental plan, expectations, experimental methods and estimated beamtime should be clarified in the proposal. All proposals will be reviewed by experts. Once your application has been scheduled, you will receive an email from the CSNS User Office, confirm the date of the experiment and the appropriate sample environment. Please complete all of the access notification/registration online at http://user.csns.ihep.ac.cn/, to ensure that the experiment can be done on schedule. After the experiment, the experimental report and User satisfaction survey must be submitted within three months.

 

In the current call for proposals, the following instruments are offered to applicants.

 

1 General Purpose Powder Diffractor (GPPD)

Instrument Scientist:Lunhua He (lhhe@aphy.iphy.ac.cn)

 

2 Multipurpose reflectometer (MR)

Instrument Scientist: Tao Zhu (tzhu@aphy.iphy.ac.cn)

 

3 Small Angle Neutron Scattering (SANS)

Instrument Scientist: Yubin Ke (keyb@ihep.ac.cn)

 

The above neutron spectrometer is still in operation and we are still debugging and testing its performance. We need to have enough time to complete the spectrometer debugging and solve the problem. If you apply for this aircraft, you have agreed to help us complete the commissioning by using the spectrometer and providing feedback to ensure that these spectrometers can provide reliable machine time services in the future. If you have any questions before applying, please contact the Spectrometer Scientist. 

 

China Spallation Neutron Source(CSNS)is a National Science and Technology Major Infrastructure Project within China's 11th five-year program, and a large-scale research platform for high-tech and multidisciplinary applications at the international frontier. The scientific goal of CSNS is to build a world-class large neutron scattering multidisciplinary research platform, providing strong research tools for basic research and high-tech development in the fields of materials science and technology, life sciences, chemistry, physics, resource environment and new energy.

 

The Chinese spallation neutron originated in September 2018 and was officially opened to the public. The first round of experiments has been completed and a second round of experiments is underway. In the first two rounds of experiments, a total of 138 applications were received, and 89 copies were approved.

 

During the first round of operation, the three spectrometers completed 40 user research subjects and achieved important research results. The users came from more than 30 universities and research institutes domestic and abroad (including Hong Kong University and Hong Kong City University in Hong Kong and Macao), University of Cambridge, UK, Queen Mary University, etc.). The General Purpose Powder Diffractometer has completed 20 user subjects, including new hydrogen storage materials, lithium ion batteries, new superconducting materials, reduction defect oxide catalysts, high strength steel and fatigue samples, focusing on new energy, new materials and engineering materials. The microscopic mechanism of the process, as well as the difficulty of applying key technologies. The Multi-function Reflectometer has completed 7 user subjects, covering solar cell films, spintronics, dilute magnetic semiconductors, material irradiation effects, soft materials, etc., providing strong support for studying the structure and magnetic properties of thin film materials. The Small-Angle Neutron Spectrometer has completed 13 user subjects, including ODS steel, high-strength and high-toughness steel, high-strength aluminum alloy, Ni-based superalloy, magnetostrictive alloy, high-performance metallic glass, etc., to provide a study on nanoscale structural evolution in high-performance materials. Direct characterization.
