²³⁶U (T_1/2 = 23 My) is an excellent monitor for nuclear contamination in the environment. Indeed, spent nuclear fuels present isotopic ratios ²³⁶U/²³⁸U several orders of magnitude higher than natural samples. ²³⁶U also provides a useful fingerprint to identify and trace nuclear material for safeguards purposes. Here we describe a new beamline for the discrimination of ²³⁶U using the accelerator mass spectrometry (AMS) technique. This system comprises a Wien velocity filter and a 6.7 m long time-of-flight (ToF) path with a focusing quadrupole. The ToF is determined by a time zero detector and a surface barrier detector, which also provides an energy measurement. The capability of the system to discriminate ²³⁶U from the much more abundant isotopes ²³⁵U and ²³⁸U is shown. While sensitivity values of ²³⁶U/²³⁸U ≈ 10^-8 were achieved, ongoing works aim to improve this performance.
