The effective differential scattering cross section of a 0.1cm standard water sample at ambient temperature (T = 298 K), used for absolute calibration of SANS‐data, has been determined at D11 with its BF 3 ‐gas detector. Systematic calibrations against primary standards were done in the wavelength range 4.5 ≤ [Å] ≤ 20. The standard samples are well‐characterised polymer solutions and blends with known differential scattering cross sections. Data are compared to previous measurements at D11 and to recent results obtained at D22, equipped with a 3 He gas‐detector.
