Project Title: Fusion Science for Clean Energy: Gamma-ray Spectroscopy diagnostic for WEST [NRF 3/23 SSV]

Project Introduction: As part of our Fusion Science for Clean Energy programme, we have two openings for Research Fellow to undertake experimental research on Runaway Electron (RE) beams in the WEST tokamak and in a dense plasma focus device using high-rate gamma-ray spectroscopy. RE beams typically occur during tokamak plasma disruptions and in pinched plasma disruptions in dense plasma focus devices. Bremsstrahlung scattering of these energetic electrons orbiting within the machine produce gamma-rays (of energy up to ~20 MeV) \xe2\x80\x93 making Gamma-Ray Spectroscopy (GRS) one of the most essential diagnostics for experimental studies of RE beams. Because they can have a large amount of energy, RE beams represent a serious risk of damage to the tokamak. Moreover, this risk increases as the size of machine increases. Consequently, research on RE beams is becoming increasingly important as the size of tokamaks will likely continue to increase over the coming decades. The GRS diagnostic measurements planned for WEST are aimed at understanding and minimizing the damage risk posed by RE beams. GRS diagnostics will be developed and tested initially in Singapore on a dense plasma focus device which also produces gamma-rays due to plasma instabilities.
