Lx255 hs detector

Manufactured by Rayonix

Sourced in United States

The LX255-HS detector is a high-speed X-ray detector designed for applications requiring fast data acquisition. It features a 255 x 255 pixel array and can operate at frame rates up to 200 Hz. The detector utilizes a scintillator-based sensor to convert X-rays into visible light, which is then detected by a CMOS image sensor.

X-ray
powder diffraction patterns at room temperature were collected by
using a Philips X’pert PRO automatic diffractometer operating
at 40 kV and 40 mA, in theta–theta configuration, secondary
monochromator with Cu-Kα radiation (λ = 1.5418 Å)
and a PIXcel solid-state detector (active length in 2θ 3.347°).
Data were collected from 5° to 50° 2θ (step size =
0.026 and time per step = 60 s) at room temperature.
Furthermore,
the X-ray diffraction profiles during the crystallization and melting
process were collected following the procedure and conditions of nonisothermal
experiments conducted in the DSC equipment. Wide-angle X-ray scattering
(WAXS) experiments were measured at beamline BL11-NCD in the ALBA
Synchrotron (Barcelona, Spain). Aluminum pans were employed to place
samples in the beam path. A THMS600 Linkam hot stage and a liquid
nitrogen cooling device were employed for temperature control and
to heat and cool the samples. The X-ray energy source amounted to
12.4 keV. For WAXS, the sample–detector distance was 132.6
mm with a 21.2° tilt angle, and chromium(III) oxide was employed
to do the calibration (Rayonix LX255-HS detector, Evanston, IL, U.S.A.,
with a resolution of 1920 × 5760 pixels and pixel size of 44
μm²).

The samples were examined at room temperature by simultaneous small angle x-ray scattering and wide angle X-ray scattering (SAXS/WAXS) measurements at beamline BL11-NCD at the ALBA Synchrotron Radiation Facility, in Barcelona, Spain. The energy of the X-ray source was 12.4 keV (λ = 1.0 Å). In the WAXS configuration, the patterns were recorded using a Rayonix LX255-HS detector with an active area of 255 × 85 mm (pixel size: 40 µm²), the distance employed was 15.5 mm with a tilt angle of 27.3°. In the case of SAXS configuration, the sample detector was a Pilatus 1M (from Dectris) with an active area of 168.7 × 179.4 mm (pixel size: 172 µm²) and the sample-to-detector distance was 6463 mm with tilt angle of 0°, covering a scattering vector (q) range from 0.2–2.5 nm⁻¹. The calibration was performed employing silver behenate and Cr₂O₃ standards. The intensity profile was output as the plot of the scattering intensity vs. scattering vector (

The in-plane and out-of-plane order of multilayer films on silicon was investigated by GIWAXS. The measurements were carried out at the BM26B-Dubble beamline of the European Synchrotron Radiation Facility (ESRF, Grenoble, France) and at the NCD-SWEET beamline of the ALBA synchrotron (Barcelona, Spain). The data here reported were collected under the following experimental conditions: the samples were mounted on a rotating stage allowing measurements under different azimuthal orientations (the φ angle between the beam incidence plane and the film compression direction c, as shown in Figure 4); the beam energy was 8.00 keV (wavelength λ = 1.55 Å) and the beam size was 111 × 12 μm² (width × height); the sample-to-detector distance was D = 198 mm and the fixed incident angle was set at α_in = 0.16°, leading to an irradiated area on the sample of ~0.5 mm²; all the patterns were recorded at room temperature, with an exposure time of 30 s, using an LX255-HS detector (Rayonix, Evanston, IL, USA).

In situ SAXS/WAXS of Crystallization

Check if the same lab product or an alternative is used in the 5 most similar protocols

Simultaneous in situ small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS) experiments were performed at the ALBA Synchrotron facility in Barcelona (Spain), beamline BL11-NCD. A Linkam THMS600 (Linkam, Surrey, UK) hot stage coupled to a liquid nitrogen cooling system was used to cool and heat the samples, which were previously placed into glassy capillaries. The same thermal protocol adopted in the non-isothermal DSC experiments was used to get the SAXS/WAXS patterns, in which crystallization and melting of the samples are followed, thus obtaining comparable results by the two different techniques.
The X-ray energy source was 12.4 keV (λ = 1.03 Å). For the SAXS setup, the distance between the sample and the detector (ADSC Q315r detector, Poway, CA, USA, with a resolution of 3070 × 3070 pixels, pixel size of 102 µm²) was 6463 mm with a tilt angle of 0°. Calibration was performed with silver behenate. Regarding WAXS configuration, a distance of 132.6 mm was used between the sample and the detector, with a tilt angle of 21.2°. Chromium (III) oxide (Rayonix LX255-HS detector, Evanston, IL, USA, with a resolution of 1920 × 5760 pixels, pixel size of 44 µm²) was employed for calibration. Scattering intensity as a function of scattering vector, q = 4πsinθλ⁻¹ data are obtained, where λ is the X-ray wavelength, and 2θ is the scattering angle.

X-ray scattering (WAXS) experiments were measured simultaneously at
beamline BL11-NCD in the ALBA Synchrotron (Barcelona, Spain). Capillaries
were employed to place samples in the beam path. A THMS600 Linkam
hot stage together with a liquid nitrogen cooling device was employed

WAXS and GIWAXS Characterization of Polymer Films

Check if the same lab product or an alternative is used in the 5 most similar protocols

Wide-angle X-ray scattering experiments at the transmission geometry and at the grazing incidence geometry (WAXS and GIWAXS, respectively) were performed at the NCD-SWEET beamline of the ALBA Synchrotron, located in Cerdanyola del Valle `s, Spain. The wavelength of the X-rays, l, was 0.9998 Å (12.4 keV), the sample-to-detector distance was 22.91 cm and, in case of the in vitro polymerized films, the angle of incidence, a i , was set at 0.161. The diffracted intensity was recorded using a Rayonix LX255-HS detector, which consists of a pixel array of 1920 Â 5760 (H Â V) and a pixel size of 44 Â 44 mm 2 . Data were normalized by the incident photon flux and the acquisition time. Flat field, polarization, solid angle and efficiency corrections were additionally applied to the 2D GIWAXS images. The scattering vector q was defined with respect to the center of the incident beam and has a magnitude of q = (4p/l)sin(y), where 2y is the Bragg reflection angle. An azimuthal integration has been performed on the 2D images to obtain the corresponding 1D scattering patterns. 1D scattering patterns are presented herein after background subtraction.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
