Following successful campaigns on the compact high field spherical tokamak ST40, resistive gold foil bolometers have now been installed to measure radiated power profile. Positioned midplane, two bolometer cameras offer perspectives of horizontal and vertical planes, while third camera, situated above provides a view top divertor plates, including X-point strike points. These use commercial off-the-shelf data acquisition platform with modules specifically designed for in Wheatstone bridge...
This paper provides a comprehensive study of neutron calibration methodologies, specifically highlighting the capabilities for n–γ discrimination in diamond and EJ-309, stilbene scintillation detectors. The process detailed this includes pulse height analysis shape discrimination, relying on charge deposition resulting from both γ interactions. Utilizing 60Co 252Cf radiation sources, energy spectra these sources are obtained. characterized detectors were used ST40 experiments allowed...
Abstract We present a new state-of-the-art Triple Wavelength Spectrometer (TriWaSp), recently deployed on ST40, high field low aspect ratio spherical tokamak. The TriWaSp has range of possible applications due to its flexible design; the current configuration focuses charge exchange recombination spectroscopy from carbon and neon impurities in ST40 plasma. This paper discusses detailed setup system presents initial ion temperature measurements using single line sight, which show good...
As part of its roadmap to developing commercial fusion plants, Tokamak Energy Ltd. operates the high field spherical tokamak ST40. Studies on this device will help expand physics basis by characterizing confinement and triple product. In support this, bolometers broadband x-ray sensitive diodes can provide information key energy loss mechanisms plasma. These include core magnetohydrodynamic activity that deteriorates confinement, such as sawtooth crashes be used characterize relaxations in...
