The long-wavelength MX beamline I23 at Diamond Light Source has been added to the current Call for Proposals (deadline 1st Oct) for experiments from April 2018.
This novel instrument can offer unique opportunities expanding the wavelength range for MX towards and beyond the sulphur K edge (lambda ~ 5 A). Potential applications are: - Native SAD - Use of strong anomalous signal from M-edges to phase large complexes - Location of sulphur or phosphorus atoms in anomalous difference fourier maps to assist model building - Identification of light atoms like chlorine, potassium and calcium in anomalous difference fourier maps above and below the respective edges The complete end station and detector are in vacuum, hence all measured signal is either from the sample, buffer or sample mount. Special thermally conductive sample mounts are required for experiments. We are currently working on the logistics on how to make sample mounts accessible for the experiments and adaptors to allow fast screening on the existing Diamond beamlines. If you are interested, we strongly encourage you to read the beamline paper (https://doi.org/10.1107/S2059798316001078) which describes the instrument. During the extended commissioning phase, we have solved several difficult native phasing problems and identified or confirmed the atom type for (unknown) peaks present in the electron density for various projects. While the sample mounts are different from standard sample holders, we can use adaptors for pre-screening samples at our high-throughput beamlines in Diamond.
