MAX-Lab MX Beamlines

The MAX-lab facility includes three beamlines for macromolecular crystallography, all using the same superconducting wiggler located at the MAX II 1.5 GeV storage ring.

The I911-3 beamline is energy tunable in the range 6.2 – 16.5 keV (0.75 – 2.0 Å). The optics consists of an Rh-coated collimating mirror, a fixed exit double crystal monochromator (Si111) and an Rh-coated toroidal focusing mirror. The experimental set-up includes a MD2 microdiffractometer with a MK3 mini-kappa, on-axis sample viewing, three-click centring and an Xflash silicon drift diode fluorescence detector. Diffraction data are collected using a Marmosaic 225 detector. The Xflash silicon drift diode fluorescence detector can be used both for fluorescence scans (scanning the incoming X-ray beam energy over the absorption edge of a particular element) and measuring fluorescence spectra to, for example, quickly identify elements in the crystal. The beamline has a CATS automatic sample changer with a capacity of 90 samples using standard EMBL/ESRF pucks. The CATS sample changer can also be used for screening crystallisation plates for diffracting crystals. An EMBL Grenoble-type humidity control device (HC1) is available on request for optimising the diffraction properties of crystals or test samples at room temperature.

I911-2 is a fixed wavelength beamline (1.04 Å) equipped with a MarDTB goniostat and a Mar165 CCD detector. The beamline has a Si111 monochromator tangentially bent to focus in the horizontal and a curved multilayer mirror to focus in the vertical.

I911-5 is a fixed wavelength beamline (0.97 Å) equipped with a MarDTB goniostat and a Mar165 CCD detector. The beamline has a flat diamond-111 monochromator that focuses in the horizontal plane and a curved multilayer mirror to focus in the vertical.
