Neutron rates and fast-ion transport in ASDEX Upgrade fusion plasmas

In a nuclear fusion plasma, neutrons are produced in fusion reactions between energetic plasma ions. Recently, a systematic deficit of such neutrons has been reported at the JET and MAST fusion devices when compared to theoretical simulations based on plasma transport codes. This could potentially be related to an as yet unidentified mechanism of fast-ion transport in the plasma. Such a mechanism could redistribute energetic ions from the plasma core, thus lowering the overall fusion and neutron production rates in the plasma. This could have wide-ranging consequences for future fusion devices, so it is important to understand the origin and generality of this result.

The goal of this project is to establish whether such a neutron “deficit” is also present in the ASDEX Upgrade fusion device, and if so under which conditions. The student will extract measured neutron rates for various ASDEX plasmas under a range of operating conditions and in the presence/absence of various plasma instabilities that could affect fast-ion transport. The rates will be compared to theoretical predictions using the TRANSP code, and the conditions under which significant discrepancies might occur should be assessed. Finally, possible explanations for any neutron deficit should be evaluated, assisted by measurements from other diagnostics.

Forudsætninger

Experience with Matlab or equivalent and an interest in data analysis and modelling techniques. Some knowledge of fusion plasma physics will be advantageous.
