Overview of Ignitor performance predictions

Quasi-stationary subignited regimes are investigated for Ignitor using the JETTO transport code by controlling the isotopic composition of the plasma and applying appropriate pulses of additional heating to the plasma column. The analysis includes sawthooth oscillations that are expected to arise at the end of the current ramp-up. The two primary ion species (Deuterium and Tritium) evolve separately under independent inflows. The results of the simulations confirm that a careful balance between main iion inflow and RF power injection allows a large range of possibilities for producing sub-ignites discharges throughout the plasma current flatto

A community-built calibration system: The case study of quantification of metabolites in grape juice by qNMR spectroscopy

Nuclear Magnetic Resonance (NMR) is an analytical technique extensively used in almost every chemical laboratory for structural identification. This technique provides statistically equivalent signals in spite of using spectrometer with different hardware features and is successfully used for the traceability and quantification of analytes in food samples. Nevertheless, to date only a few internationally agreed guidelines have been reported on the use of NMR for quantitative analysis. The main goal of the present study is to provide a methodological pipeline to assess the reproducibility of NMR data produced for a given matrix by spectrometers from different manufacturers, with different magnetic field strengths, age and hardware configurations. The results have been analyzed through a sequence of chemometric tests to generate a community-built calibration system which was used to verify the performance of the spectrometers and the reproducibility of the predicted sample concentrations
