Fusion Research

For tokamak fusion research Hiden Analytical have developed special RGA’s quadrupole mass spectrometer systems, including the DLS range quadrupole mass spectrometers for research and the HAL 101X RGA for monitoring, diagnostics and analysis applications at the tokamak.

The DLS systems include a threshold ionization mass spectrometry (TIMS) mode that separate Deuterium (D₂) and helium-4 (⁴He). TIMS accounts for the energy released by electrons at the ionization source and creates a unique fingerprint for elemental species, allowing the equipment to recognize elements of similar atomic masses – including deuterium and helium-4. The DLS-1 is a real-time quantitative RGA with a mass range of 1-100 amu and a 0.5 eV electron energy resolution over the range of 150 eV.

The DLS-20 system includes a 20 mm pole diameter quadrupole analyzer that operates in both the zone 1 and the zone H stability regions, that provide both ultra-high mass resolution using zone H, with peak width as small as 0.003 amu to 20 amu, and using ultra-high sensitivity analysis using zone 1, over the mass range to 200 amu.

The HAL101X RGA is designed for critical monitoring, diagnostics, and analysis in tokamak operations, and includes new transformer coupled RF technology. The transformer coupled technology enables the analyzer to be separated from the RGA electronics, the RF and interface units by extended distances of up to 80m enabling RGA operation in both the standard RGA and TIMS modes in the harsh radiation environment of the tokamak.

Hiden Analytical are leading suppliers of quadrupole mass spectrometry equipment, with over 35 years’ experience in designing and manufacturing mass analysis instrumentation for an enormous range of applications.

Few of the sectors that we have provided for exhibit as much potential to change the world as fusion research, which researchers believe will begin supplementing global power grids in coming decades. Our quadrupole systems for fusion research are on the leading edge of energy analysis, with innovative benefits over conventional equipment.
