Technical details

ID29 is intended for high intensity, high energy resolution MAD and SAD measurements over a wide range of X-ray wavelengths (0.7 - 2.1 Å). ID29 is equipped with a MicroDiffractometer (MD2) - which allows to tailor the beam sizes down to 75 (full beam), 50, 30, 20 and 10 microns in diameter - and with a FlexHCD Sample Changer. Diffraction data are recorded with a fast readout Pilatus 6M-F pixel detector detector (Dectris LTD) that allows data collection with a maximum frame rate of 25 images/s.
