DLS-1: A Quadrupole Residual Gas Analyzer

Hiden Analytical's DLS-1 is a quadrupole residual gas analyzer designed for advanced tokamak fusion research. The DLS-1 operates in threshold ionisation mass spectrometric (TIMS) mode, delivering real-time quantification of gas species across a mass range of 1–100 atomic mass units (AMU). This enables the clear identification of unique spectral fingerprints for gases critical to fusion research parameters.

With precise control of electron energy as standard, along with a range of available ion sources, the DLS-1 quadrupole residual gas analyzer provides a reliable and adaptable solution for advanced fusion research applications.

Overview

Fusion is widely considered a leading alternative energy source. By harnessing the fusion of hydrogen isotopes, such as deuterium (D₂), to form helium (He), researchers aim to deliver a clean, sustainable energy solution for the future.

Facilities around the world continue working to translate this theory into practical application, with the tokamak remaining the most established fusion research device. However, challenges associated with the classical torus design include significant energy losses and the complexity of separating D₂ from helium (⁴He).

The Hiden DLS series systems are specifically designed for fusion applications where the analysis of hydrogen isotopes and deuterated compounds is critical.

The DLS-1 mass spectrometer enables real-time quantitative analysis of complex gas and vapor mixtures by using dedicated templates for measuring deuterium in helium and other deuterated species. This capability positions it as a highly effective solution for validating fuel purity in fusion research environments.
