Imaging Nanoscale Magnetic Structures With Polarized Soft X-Ray Photons
IEEE Photonics Journal, 2010 Imaging nanoscale magnetic structures and their fast dynamics is scientifically interesting and technologically of highest relevance. The combination of circularly polarized soft X-ray photons, which provide a strong X-ray magnetic circular dichroism ...

A soft X-ray halo of the LMC? [PDF]
International Astronomical Union Colloquium, 1997 AbstractROSAT X-ray observations of the LMC show several X-ray shadows in the ¾ keV and 1.5 keV bands. The ¼ keV band is dominated by emission of the galactic foreground. It is uncertain whether there is additional soft X-ray contribution from the LMC.

Formation of x-ray Newton’s rings from nano-scale spallation shells of metals in laser ablation
AIP Advances, 2017 The initial stages of the femtosecond (fs) laser ablation process of gold, platinum, and tungsten were observed by single-shot soft x-ray imaging technique. The formation and evolution of soft x-ray Newton’s rings (NRs) were found for the first time. The

Soft X-rays and Secondary Electrons [PDF]
Physical Review, 1924 Velocity distribution of photo-electrons excited by soft x-rays.— The apparatus was similar to that used in the magnetic analysis of β rays. Soft x-rays excited by primary electrons with 150 to 1500 volts energy, fall on a radiator of W, Pt, Al, etc. The photo-electrons emitted in a plane approximately normal to the uniform magnetic field acting, each ...

Broadband soft x-ray polarimetry [PDF]
SPIE Proceedings, 2010 We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position angle is measured to determine three Stokes parameters: I, Q, and U -- all as a ...

The Soft X-ray Excess in Quasars and Deep X-ray Surveys [PDF]
Symposium - International Astronomical Union, 1994 We examine the surface density of quasars expected in the ROSAT PSPC surveys, using quasar optical luminosity functions and model continuum spectra including a soft X-ray excess. We show that the surface density is a sensitive function of the characteristic energy of the soft excess, and the absorption within the quasar as well as the interstellar ...

Soft X‐Ray Imaging of Earth's Dayside Magnetosheath and Cusps Using Hybrid Simulations
Geophysical Research Letters, 2023 Interactions between solar wind ions and neutral hydrogen atoms in Earth's exosphere can lead to the emission of soft X‐rays. Upcoming missions such as SMILE and LEXI aim to use soft X‐ray imaging to study the global structure of the magnetosphere ...
