We developed a point-fluorescent-source-based white-light interferometer for high-resolution reflectometry, range-gating imaging, and group-velocity-dispersion measurement. The laser-pumped point fluorescent source has 9 mW of power and a spatial coherence of 0.97, which allows it to be used like a laser beam. Owing to its 40-nm FWHM spectral width, the width of its temporal autocorrelation is ...

We have demonstrated a proof-of-concept optical device that can produce true time delays for a phased-array radar. This device combines White cells of differing lengths with a spatial light modulator to select between the paths on multiple bounces of a given beam. The approach can handle thousands of light beams and produce hundreds of different delays. The number of delays is proportional to t...

A full-field hard X-ray imaging beamline (BL-4) was designed, developed, installed and commissioned recently at the Indus-2 synchrotron radiation source at RRCAT, Indore, India. The bending-magnet beamline is operated in monochromatic and white beam mode. A variety of imaging techniques are implemented such as high-resolution radiography, propagation- and analyzer-based phase contrast imaging, ...

New projects being implemented or planned at CERN, such as the LHC Injectors Upgrade (LIU), High-Luminosity (HL-LHC) Future Circular Collider (FCC), motivate change of several architectural paradigms in Low Level RF systems (LLRF). In upgraded Super Proton Synchrotron (SPS) LLRF, distribution RF, revolution frequency, settings and synchronization timings will rely on a deterministic link, White...

Murals are a significant cultural heritage of humanity, and one the conservation studies is to control growth microorganisms. General biocide agents can be used preserve murals while also providing new organic carbon sources increasing environmental pollution. In recent years, radiation technology has shown promising prospects for use in protection. Five microorganisms often found were irradiat...
