“…The intensity monitors must be small enough to fit into the experimental setup, fast enough to cope with a repetition rate of 4.5 MHz and highly transmissive. Diamond-based solidstate detectors are well known from synchrotron radiation applications, where they are used as beam-position monitors (BPMs) (Shu et al, 1998;Bergonzo et al, 1999;Desjardins et al, 2018). A diamond-based solid-state ionization chamber is located in the DES.…”

The Materials Imaging and Dynamics (MID) instrument at the European X-ray Free-Electron Laser Facility (EuXFEL) is equipped with a multipurpose diagnostic end-station (DES) at the end of the instrument. The imager unit in DES is a key tool for aligning the beam to a standard trajectory and for adjusting optical elements such as focusing lenses or the split-and-delay line. Furthermore, the DES features a bent-diamond-crystal spectrometer to disperse the spectrum of the direct beam to a line detector. This enables pulse-resolved characterization of the EuXFEL spectrum to provide X-ray energy calibration, and the spectrometer is particularly useful in commissioning special modes of the accelerator. Together with diamond-based intensity monitors, the imager and spectrometer form the DES unit which also contains a heavy-duty beamstop at the end of the MID instrument. Here, we describe the setup in detail and provide exemplary beam diagnostic results.

“…The position of the beam is reflected by an electronic grade single-crystal chemical-vapour-deposition (CVD) diamond X-ray BPM (Desjardins et al, 2013) located downstream of the sample slits and upstream of the fast shutter. The intensity of the X-rays and the flux deposited on the sample are measured on a duo-lateral position-sensitive detector (PSD; Desjardins et al, 2018). An additional placeholder for diagnostic tools is located downstream of the mirror box (Fig.…”

The undulator beamline PROXIMA-1 at Synchrotron SOLEIL scheduled its first users in March 2008. The endstation is dedicated to biomolecular crystallography experiments, with a layout designed to favour anomalous data recording and studies of crystals with large cell dimensions. In 12 years, the beamline has accommodated 4267 shifts of 8 h and more than 6300 visitors. By the end of 2020, it saw 1039 identified published scientific papers referring to 1415 coordinates deposited in the Protein Data Bank. The current paper describes the PROXIMA-1 beamline, including the recent specific implementations developed for the sample environment. The setup installed in the experimental station contains numerous beam-shaping equipment, a chi-geometry three-axis goniometer, a single-photon-counting pixel-array X-ray detector, combined with a medium-throughput sample exchange robot. As part of a standard experimental scheme, PROXIMA-1 can also be accessed via `mail-in' services or remotely.

“…4(a)], despite slightly larger deviations observed in the region of higher X-ray energy. We note that the flux spectra were measured from the sum current of the quadrant-diamond XBPM Civi-2 (situated at the 40 m sample position), following a previous report (Desjardins et al, 2018). In the flux deduction, all absorptions from the filters and windows along the beam path were taken into account, including the attenuation due to the two diamond filters and the thin metal coatings of Rigi and Civi-2 XBPMs, and the Be windows.…”

Optical design and performance of the biological small-angle X-ray scattering beamline at the Taiwan Photon Source

et al. 2021

The optical design and performance of the recently opened 13A biological small-angle X-ray scattering (SAXS) beamline at the 3.0 GeV Taiwan Photon Source of the National Synchrotron Radiation Research Center are reported. The beamline is designed for studies of biological structures and kinetics in a wide range of length and time scales, from angstrom to micrometre and from microsecond to minutes. A 4 m IU24 undulator of the beamline provides high-flux X-rays in the energy range 4.0–23.0 keV. MoB4C double-multilayer and Si(111) double-crystal monochromators (DMM/DCM) are combined on the same rotating platform for a smooth rotation transition from a high-flux beam of ∼4 × 1014 photons s−1 to a high-energy-resolution beam of ΔE/E ≃ 1.5 × 10−4; both modes share a constant beam exit. With a set of Kirkpatrick–Baez (KB) mirrors, the X-ray beam is focused to the farthest SAXS detector position, 52 m from the source. A downstream four-bounce crystal collimator, comprising two sets of Si(311) double crystals arranged in a dispersive configuration, optionally collimate the DCM (vertically diffracted) beam in the horizontal direction for ultra-SAXS with a minimum scattering vector q down to 0.0004 Å−1, which allows resolving ordered d-spacing up to 1 µm. A microbeam, of 10–50 µm beam size, is tailored by a combined set of high-heat-load slits followed by micrometre-precision slits situated at the front-end 15.5 m position. The second set of KB mirrors then focus the beam to the 40 m sample position, with a demagnification ratio of ∼1.5. A detecting system comprising two in-vacuum X-ray pixel detectors is installed to perform synchronized small- and wide-angle X-ray scattering data collections. The observed beamline performance proves the feasibility of having compound features of high flux, microbeam and ultra-SAXS in one beamline.
