Postdoctoral research assistant for polarized gas system 
Employer 
China Spallation Neutron Source (CSNS) 
Location 
CSNS, Dongguan, China 
Introduction 
The sample environment group at the China Spallation Neutron Source (CSNS) is looking for a 
postdoctoral research assistant candidate for the development of polarized 3He gas system. 
Description of Institution 
The China Spallation Neutron Source located at Dongguan is one of the largest science and 
technology infrastructure projects in China. The facility currently includes a powerful linear 
proton accelerator, a rapid circling synchrotron, a target station and three neutron 
instruments. Currently there are more than 400 scientists and engineers working together in 
Dongguan on the CSNS project. Once complete, CSNS will support research teams, including 
many from China and other countries, in addressing significant global challenges that range from 
healthcare and security to ecology and fuel technology. 
Job description 
The sample environment group at CSNS is developing an integrated Spin-Exchange Optic 
Pumping (SEOP) system to provide reliable 3He for the purpose of polarized neutron research. 
The development includes both in-situ and off-situ polarized 3He system and is expected to 
provide support to various polarized neutron beamline at the CSNS in the future. The sample 
environment group is now seeking a postdoctoral research assistant candidate to support the 
development work and perform related research. The candidate will work with other members of 
the team and cooperate with the instrument scientist and engineers, and contribute to the overall 
development which includes: 
1. Spin Exchange Optical Pumping (SEOP) system principle and application research 
2. Design, construction and test of various SEOP prototype system 
3. Research of polarized neutron based on the developed SEOP system 
Successful candidate is expected to contribute to the delivery of feasible SEOP system within the 
initial term of 2 year, with the potential long-term position upon term completion. The postdoc 
candidate is also encouraged to perform his or her own research in the related area of polarized 
gas or polarized neutron.  The CSNS will provide postdoctoral research assistant an annual salary 
of ?300,000 ($44,645), as well as postdoc apartment during the term. 
Requested Profile 
Essential qualification and experience: 
· Ph.D. degree in physics or related field acquired within 3 years 
· Extensive practical experience in instrument development 
· Evidence of a strong independent research profile in relevant science areas commensurate 
with experience 
· Ability to work collaboratively and individually. 
· Good interpersonal communication and presentation skills.   
· Flexibility to work out-of-hour according to neutron experiment schedule 
· Capable of communicating in English. Mandarin speaking is highly preferred but not 
required. 
· Willingness to international travel and relocate to Dongguan China during employment. 
Desirable experience: 
· Experience in Spin Exchange Optical Pumping (SEOP) system development 
· Experience in polarized neutron instrument development 
· Experience with vacuum, cryogenic system and high-power laser system 
· Experience with magnetic field simulation, neutron optics simulation and data analysis. 
Working knowledge with Matlab, Python, Magnet or McStas 
· Availability to commence position shortly after appointment
