BackgroundIsotope separation technology plays a crucial role in basic scientific research, the national economy, and national security strategies. Existing separation technologies face challenges such as high energy consumption, low efficiency or limited applicability.PurposeThis study aims to verify the feasibility of single-photon separation of SF6 isotopes and to explore the effects of key parameters on separation performance.MethodsSeparation was achieved by combining supersonic molecular beam cooling with selective single-photon infrared laser excitation. A quadrupole mass spectrometer was used for online monitoring, experimental parameters were adjusted, and their impact on the separation factor was calculated.ResultsThe experimental results show that under the optimal conditions (laser close to the nozzle, sample gas pressure at 0.4 MPa, and laser power at 18 W), the separation selectivity exceeds 5.ConclusionsThe research results confirm the feasibility of single-photon separation of SF6 isotopes and provide important foundational data for the application of laser isotope separation methods domestically.
