Abstract The JET 2019–2020 scientific and technological programme exploited the results of years concerted engineering work, including ITER-like wall (ILW: Be W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power 2019–2020, tested technical procedural preparation for safe operation with tritium. Research along three complementary axes yielded wealth new results. Firstly, plasma delivered scenarios...
Abstract JET, the world’s largest operating tokamak with unique Be/W wall and tritium handling capability, completed a Deuterium-Tritium (D-T) campaign in 2021 (Maggi et al 29th Fusion Energy Conf. ) following decade of preparatory experiments, dedicated enhancements, technical rehearsals training (Horton 2016 Eng. Des. 109–111 925). Operation raises significant technical, safety scientific challenges not encountered standard protium or deuterium operation. This contribution describes...
The development of new target stations for radioisotope production based on a dedicated 70 MeV commercial cyclotron (for protons) is described. Currently known as the South African Isotope Facility (SAIF), this initiative will free existing separated-sector (SSC) at iThemba LABS (near Cape Town) to mainly pursue research activities in nuclear physics and radiobiology. It foreseen that completed SAIF facility realize three-fold increase capacity compared current programme SSC.
The South African Isotope Facility (SAIF) is a project in which iThemba LABS plans to build radioactive-ion beam (RIB) facility. divided into the Accelerator Centre of Exotic Isotopes (ACE Isotopes) and for Beams Beams). For ACE Isotopes, high-current, 70 MeV cyclotron will be acquired take radionuclide production off existing Separated Sector Cyclotron (SSC). A freed up SSC then available an increased tempo nuclear physics research serve as driver accelerator project, protons used direct...
The iThemba Laboratory for Accelerator Based Sciences is based around a K=200 Separated Sector Cyclotron (SSC), which used nuclear physics research, radionuclide production, and hadron therapy. It plans in future to build an ISOL radioactive-ion beam facility. Protons will be the direct fission of Uranium, produce fragment beams. A high-current, 70 MeV cyclotron acquired take production off SSC. freed up SSC then available increased tempo research. project has begun with RIB “test facility”,...
The development of new target stations for radioisotope production based on a dedicated 70~MeV commercial cyclotron is described. Currently known as the South African Isotope Facility (SAIF), this initiative will free existing separated-sector (SSC) at iThemba LABS (near Cape Town) to mainly pursue research activities in nuclear physics and radiobiology. It foreseen that completed SAIF facility realize three-fold increase capacity compared current programme SSC.
Traditional spiral inflectors of the Belmont-Pabot type are commonly used for axial injection external ion beams into cyclotrons. These designed to control trajectory central path, and do not actively focus beam in vertical longitudinal directions. This can introduce effects such as a large divergence debunching spread, making it difficult match line emittance cyclotron acceptance. In an attempt overcome this, some recent have started incorporating electrodes specially shaped produce field...
