The Institute of High Energy Physics held its 2016 Seminar for Strategic Planning from April 21st to 22nd in Dongguan Campus, Shenzhen. IHEP Directors, members of the IHEP Science Committee and leaders from the various research divisions and administrative departments attended the meeting.
Prof. Robert McGreevy, Director of the ISIS pulsed neutron and muon source at the Rutherford Appleton Laboratory, UK, together with Prof. John Bouchard, Open University, UK, Mr. Zhang Shuyan and Mr. Zhang Peng, Director and Deputy Director respectively of Guangdong Materials and Genetics Polytechnic Institute, visited CSNS on April 20th, 2016.
The first tank of the Drift Tube Linac (DTL-1) of the China Spallation Neutron Source (CSNS) completed its beam commissioning on January 20th. The beam commissioning lasted for twelve days, and on January 18th, the beam reached the end of the first DTL tank with a peak current of 18 mA at 21.6 MeV, a transmission rate of 100% within the error of the Current Transformer.
The closed-cycle variable temperature system of the China Spallation Neutron Source (CSNS) passed acceptance tests on January 15th. The system is one of the important ancillary facilities for the neutron spectrometers.
All the sets of neutron beamline shutter equipment for China Neutron Spallation Source (CSNS) shielding system successfully passed acceptance tests on January 11, 2016, in Nanjing. The tests showed that all the specifications met or exceeded the design requirements.
The last set of magnet (RCS-253Q quadrupole magnet) at the Rapid Cycling Synchrotron (RCS) of China Spallation Neutron Source (CSNS) was installed in RCS tunnel on Dec. 31, 2015, marking the completion of the CSNS/RCS magnet installation.
The debugging of the first CSNS/RCS quadrupole power supply and its resonant network was successfully completed on December 15, 2015 with all the specifications meeting or better than the designed requirements.
The Third CSNS Science Committee Meeting, chaired by CAS Academician Fang Shouxian, was convened in Dongguan on December 16, 2015.Thirty five members including 11 academicians attended the meeting.
The China Spallation Neutron Source is expected to produce its first beam in 2017. Hesheng Chen and Xun-Li Wang provide an overview of this user facility and what it means for science in China and elsewhere.
