Call for five PhD Research Positions
Cryogenic system for long-distance cooling
(Full-time, salary in accordance with CUMT regulations for qualification)

China University of Mining and Technology (CUMT) is one of the top national comprehensive universities in China. The Institute of Sustainable Energy (ISE) of CUMT is a newly established centre of excellence for high-level multidisciplinary comprehensive and advanced scientific research in the areas of sustainable energy towards creation of the next generation energy system.  The ISE under leadership of the 1984 Nobel Laureate of Physics, Professor Carlo Rubbia and the Fellow of the Royal Academy of Engineering (UK), Academician of Chinese Academy of Engineering, Professor C. C. Chan, is currently focusing on the following three research fields:
• Zero Emission Energy Systems
• Innovative Energy Storage Systems
• Long Distance G-Watt Electric Power Transmission

The research fieldLong Distance G-Watt Electric Power Transmission aims atdeveloping at ISE the innovative approach to sustainabletransmission of high electric power over the long distances up to 5000 km with a novel type of superconductivity (MgB2) as an alternative to the present implementation of the Ultra High Voltage Direct Current (UHVDC) areal lines. Magnesium di-boride (MgB2) is a simple metallic compound produced from cheap and abundant materials. The cryogenic operation is possible at temperatures of pressured helium gas or liquid hydrogen. The approach has been proposed by Carlo Rubbia in 2011 and the world’s first MgB2 power cable carried of the 20 kA DC current has been developed and successfully tested at CERN in 2014. The purpose of the present program is to provide a new option for high-capacity electric power transmission over long distances with not only excellent electrical performance but also with the economic and environmental benefits. The objective is to design and test a prototype of the superconducting MgB2 transmission line that is scalable to long distances.The R&D activities are focused on developing of a low-loss cryogenic system for long-distance cooling as well as on the electrical characterization and integration of a superconducting transmission link. They are closely linked to electromagnetic and thermal modelling conducted in parallel with economic analysis and monitoring of transmission system technologies, grid expansion process and needs for installation of new transmission capacities.
For developing of the cryogenic system for long-distance cooling, ISE invites the applications for five research positions in accordance with the following tasks:

1) Cryostat design and development (C-1/2016)
2) Design of refrigeration and liquefaction system(C-2/2016)
3) Design of terminations and joints (C-3/2016)
4) Design of thermal/vacuum insulation (superinsulation) (C-4/2016)
5) Control and management of cryogens (C-5/2016)

Requirements:

• PhD in experimental physics/ mechanical engineering or similar qualification
• Strong experience in designing and practical operating of cryogenic equipment and tools
• Experience in designing and practical operating of the liquefaction systems
• Knowledge with heat transfer and ability to perform fluid mechanics calculations
• Strong experience with highly pressurized gas (He) and cryogenic fluids (LN2, LH2)
• Profound knowledge of thermal insulation and vacuum systems
• Knowledge of thermal and mechanical properties of materials at low temperatures
• Experience with high voltage applications
• Knowledge with CAD software
• Excellent English and Chinese skills (oral, written)
• Strong teamwork and communication skills to work in a multidisciplinary environment

The applications from candidates with international backgrounds are particularly encouraged.  The ISE offers an internationally competitive salary in line with candidate’s qualification, excellent working conditions and vibrant research environment.
