- Detected mass range: 1-5000 u (positive ions) and 1-3000 u (negative ions)
- Mass resolution: > 800 (measured with the background gas using the provided on-board electron impact ionizer)
- Possibility of detection: analysis of abundance and velocity distributions of particles in gas and plasma flows, positive ions, negative ions, neutrals
- Registration time resolution: A time-to-digital converter with time resolution of 0.25 ns
- Detectors: dual microchannel plate ion detector (positive and negative ions) and high-voltage discrete-dynode detector (positive ions)
- Detection sensitivity: Ion counting system allowing to detect single ions
- Environment:
- high vacuum
- ambient gases: He, O2, N2, Ar
- Vacuum system:
- ablation vacuum chamber: below 6e-5 mbar, inner dimensions: 500 mm diameter, 600 mm height.
- RETOFMS vacuum chamber with a differential pumping system:
- Under high vacuum conditions (2e-7 mbar)
- Under ambient gas conditions: RETOFMS chamber (below 2e-6 mbar) when the ambient gas pressure in the plasma chamber is 0.7 mbar
- Laser systems for ablation:
