Job announcements relevant to people interested in electronic structure calculations…

Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.

In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

PhD at UNSW Sydney – Developing shielding mate ... (No replies)

Small spherical tokamaks (ST) are alternative fusion reactor design to the the conventional large-scale Tokamak (e.g. ITER). The key advantage of ST is their small size and build cost, which makes it possible to iterate through several prototypes over a few years, as has been achieved by our partners at Tokamak Energy Ltd.

The current limitation in the advancement of spherical tokamak reactors is the need to shield critical components, such as the superconducting magnets, from the high-energy radiation produced inside the fusion plasma. Due to the space constraints, conventional shielding materials (e.g. steel, concrete, lead) are inadequate for spherical tokamaks, and new materials need to be designed to overcome this challenge.

We are developing new shielding materials that are tolerant to radiation damage caused by high-energy neutrons and gammas. The aim of this project is to develop an understanding of the radiation damage in these advanced shielding materials when exposed to fusion radiation, and the effect that these will have on the materials properties.
 
Full project description attached, and available here. Expression of interest close 31-Jul-2021.
