Summary
Researchers measured the sensitivity of Fuji image plates (IPs) for X-ray spectrometers. Sensitivity varied by up to 5% with scanner settings, highlighting the need for cross-calibration between facilities.
Area of Science:
- Nuclear Physics
- Materials Science
- Spectroscopy
Background:
- Fuji SR and MS image plates (IPs) are crucial detectors in X-ray spectrometers.
- Accurate sensitivity calibration is essential for quantitative analysis in high-energy physics experiments.
Purpose of the Study:
- To quantify the sensitivity of Fuji SR and MS image plates (IPs) across a broad X-ray energy range.
- To investigate the impact of scanner settings and pixel size on IP sensitivity.
- To assess the fading properties of MS-type image plates.
Main Methods:
- Measured IP sensitivity using radioisotopes (6-60 keV) and a Manson source (1.5-8 keV).
- Systematically examined IP sensitivity variations with scanner settings and pixel size.
- Evaluated MS-type IP fading over extended periods.
Main Results:
- IP sensitivity showed variations of approximately 5% for specific types and scanner settings.
- IP sensitivity varied by up to a factor of 2 depending on IP type and scanner parameters.
- Radioisotope technique provided insights into MS-type IP fading characteristics.
Conclusions:
- Cross-calibration of image plate scanners across different facilities is essential.
- A consistent absolute sensitivity curve from 2-60 keV requires inter-facility calibration.
- Understanding IP sensitivity variations is critical for accurate X-ray spectroscopy data.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...
