The first experimental results from a new transmissive diagnostic instrument for synchrotron X-ray beamlines are presented. utilizes single-crystal chemical-vapour-deposition diamond plate as the detector material, with graphitic wires embedded within bulk acting electrodes. resulting is an all-carbon imaging detector. Within instrument's aperture there no surface metallization that could absorb X-rays, and structures be damaged by exposure to beams. electrodes fabricated in situ using...
In this paper we demonstrate significant improvements to the stability of monochromatic X-ray beam intensity on several beamlines at Diamond, using a modulation pitch axis DCM with piezoelectric actuator. The is detected an diagnostic (e.g. ion chamber) software lock-in technique. amplitude and phase are used in feedback keep peak rocking curve, or any arbitrary position 'off-peak' which might be desired detune reject unwanted harmonics. A major advantage based system great flexibility...
A method to simulate beam properties observed at the beamline sample-point in presence of motion optical components has been developed Diamond Light Source. series stationary ray-tracing simulations are used model impact on stability caused by dynamic elements. Ray-tracing using SHADOW3 OASYS , completed over multiple iterations and stitched together, permit modelling a pseudo-dynamic beamline. As detectors operating higher frequencies become more common, is crucial. Synchrotron ring...
VMXm joins the suite of operational macromolecular crystallography beamlines at Diamond Light Source. It has been designed to optimize rotation data collections from protein crystals less than 10 µm and down below 1 in size. The beamline a fully focused beam 0.3 × 2.3 (vertical horizontal) with tuneable energy range (6–28 keV) high flux (1.6 12 photons s −1 12.5 keV). are housed within vacuum chamber minimize background scatter air. Crystals plunge-cooled on cryo-electron microscopy grids,...
Maintaining the stability of X-ray beam relative to sample point is paramount importance for beamlines and users wanting perform cutting-edge experiments. The ability detect, subsequently compensate for, variations in position with effective diagnostics has multiple benefits: a reduction commissioning start-up time, less ‘down-time’, an improvement quality acquired data. At Diamond Light Source methodical evaluation selection monochromatic Beam Position Monitors (XBPMs), using range...
A single crystal CVD diamond detector with graphitic wire electrodes running beneath the surface has been fabricated. This design is novel in that there no metallisation present within active region, and so a uniquely transmissive X-ray beam diagnostic instrument. designed to simultaneously measure position, profile, flux of an incident beam. It applications position profile monitoring, feedback stabilisation. To achieve this, short-pulse laser, focused micron-sizes using adaptive optics,...
We report on the use of single-crystal chemical vapour deposition (scCVD) diamond X-ray beam diagnostics at Diamond Light Source Ltd (DLS) for beamline commissioning and day-to-day operation. It is demonstrated that such detectors can offer synchrotron beamlines a measurement position with resolutions few 10nm kHz bandwidths. straightforward to extract extremely valuable spectral information both motion intensity, aiding in determining source vibrations or other instabilities. In this paper...
Single-crystal chemical vapour deposition (CVD) diamond detectors are an established transmissive synchrotron beamline diagnostic instrument used for beam position and intensity monitoring. A recently commercialized alternative is silicon carbide (4H-SiC) devices. These have the potential to provide same information as commercially available single-crystal CVD X-ray monitors, but with a much larger aperture. At Diamond Light Source experimental comparison of performance 4H-SiC monitors has...
Diamond Light Source [1] currently operates five beamlines for macromolecular crystallography (MX) and soon seven will serve the MX user community [2].I04, a widely tuneable (5-25 keV, core range 6-17 keV) SAD/MAD station [3] is constantly evolving with aim to provide state of art tools data collection, especially enable structure solution from increasingly difficult challenging samples.Since early 2015 beamline using an array compound refractive lenses in transfocator like device allowing...
