Ionization and heating by X-rays and cosmic rays*

open access: yesEPJ Web of Conferences, 2015
High-energy radiation from the central T Tauri and protostars plays an important role in shaping protoplanetary disks and influences their evolution. Such radiation, in particular X-rays and extreme-ultraviolet (EUV) radiation, is predominantly generated

X-ray emission characteristics in magnetically driven plasma jet experiments on PTS facility

open access: yesMatter and Radiation at Extremes, 2020
Jets are commonly observed astrophysical phenomena. To study the x-ray emission characteristics of jets, a series of radial foil Z-pinch experiments are carried out on the Primary Test Stand at the Institute of Fluid Physics, China Academy of Engineering

Tuberculous Salpingitis - possible cause of salpingo-enteric fistula

open access: yesRadiology Case Reports, 2023
Salpingo-enteric fistula is a rare disease causing infertility. It occurs when there is a connection between fallopian tube and the intestine. It can be accurately diagnosed with hysterosalpingography.

Single shot diffraction of picosecond 8.7-keV x-ray pulses

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
We demonstrate multiphoton, single shot diffraction images of x rays produced by inverse Compton scattering a high-power CO_{2} laser from a relativistic electron beam, creating a pulse of 8.7 keV x rays.

Internet hand x-rays: A comparison of joint space narrowing and erosion scores (Sharp/Genant) of plain versus digitized x-rays in rheumatoid arthritis patients

open access: yesBMC Musculoskeletal Disorders, 2002
Background The objective of the study is to examine the reliability of erosion and joint space narrowing scores derived from hand x-rays posted on the Internet compared to scores derived from original plain x-rays.

Pulmonary abnormality screening on chest x-rays from different machine specifications: a generalized AI-based image manipulation pipeline

open access: yesEuropean Radiology Experimental, 2023
Background Chest x-ray is commonly used for pulmonary abnormality screening. However, since the image characteristics of x-rays highly depend on the machine specifications, an artificial intelligence (AI) model developed for specific equipment usually ...

X-ray-Induced Heating in the Vicinity of the X-ray Interaction Point

open access: yesApplied Sciences, 2023
When X-rays pass through a material, radiation damage occurs, and heat is generated at the X-ray interaction point, which can then be transferred around the X-ray irradiation site. This X-ray-induced heat transfer can affect the temperature of the sample

Two-chicane compressed harmonic generation of soft x rays

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2011
Seeding an electron bunch prior to compression simultaneously shifts the laser modulation to shorter wavelengths while decreasing the required modulation amplitude. The final x-ray wavelength is then tunable by controlling the compression factor with the

X-ray Observations at Gaisberg Tower

open access: yesAtmosphere, 2018
We report the occurrence of X-rays at ground level due to cloud-to-ground flashes of upward-initiated lightning from Gaisberg Tower, in Austria, which is located at an altitude of 1300 m.

Multi-Lane Mirror for Broadband Applications of the Betatron X-ray Source

open access: yesPhotonics, 2021
A new generation of small-scale ultrafast X-ray sources is rapidly emerging. Laser-driven betatron radiation represents an important class of such ultrafast X-ray sources. With the sources driving towards maturity, many important applications in material
