Abstract The EXFLU batches of thin LGAD sensors with substrates of thickness between 20 and 45 μm were tested for timing performance at the DESY Test Beam Facility. The sensor designs are optimised for excellent timing resolution, and are manufactured by Fondazione Bruno Kessler. The timing performance is reported for both non-irradiated LGAD sensors and a set of 30 μm sensors irradiated up to 2.5 × 10 15 n 1 MeV eq. cm -2 . In addition, a new approach to the analysis of thin sensors is considered using differential programming to optimise a signal probability model. The results using the conventional method and this approach using machine learning are presented.
