The sensitivity of current and planned gravitational wave interferometric detectors is limited, in the most critical frequency region around 100 Hz, by a combination quantum noise thermal noise. latter dominated Brownian noise: motion originating from elastic energy dissipation dielectric coatings used interferometer mirrors. material property characterized mechanical loss angle. We have identified mixtures titanium dioxide (TiO$_2$) germanium (GeO$_2$) that show internal dissipations at...

Fast and radiation hard to face challenge of severe environment expected by future experiments at hadron colliders, such as HL‐LHC FCC-hh. Ultrafast unprecedented event rate searching for rare decays, Mu2e‐II, ultrafast time flight system colliders. Cost‐effective homogeneous calorimeter concept both electromagnetic jet mass resolutions required proposed Higgs...
Because of their high stopping power and fast bright scintillation, cerium doped silicate based heavy crystal scintillators, such as GSO, LSO, LYSO, have been developed for medical instruments. Their applications in energy nuclear physics, however, are limited by lacking quality crystals sufficiently large size. The optical scintillation properties, including the transmittance, emission excitation spectra light output, decay kinetics response uniformity, well degradation under gamma-ray...

Abstract Gravitational-wave detectors impose exceptionally rigorous demands on optical coatings, which include high reflectivity, low thermal noise, absorption, scatter, and minimal defect counts. Simultaneously satisfying the noise absorption requirements is particularly challenging. One promising approach to use three or more materials in a single coating. In this work we characterize such multimaterial coating made using index silica (SiO 2 ), tantala (Ta O 5 substoichiometric x ). We...

Radiation-induced lymphopenia have been linked worse prognosis across various cancer types. Despite being largest secondary lymphoid organ, spleen is not currently designated as an organ at risk in radiation therapy protocols. This study seeks provide a reference splenic dose-volume constraints clinical radiotherapy practice. Methods: To exclude influence of tumor...
Barium fluoride (BaF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) crystal has a fast scintillation light peaked at 195 and 220 nm with sub-ns decay time. This ultrafast promises wide application in an area where extreme timing is important, such as future high-energy physics experiments, gigahertz hard X-ray imaging, time-of-flight positron emission tomography. BaF crystal, however, also slow component 310 time of about 600 ns,...
We report the characterization of superlow-loss optics used in second-generation gravitational-wave detectors currently operation. The sapphire test-mass mirrors KAGRA detector are introduced as an example, but techniques here common to all detectors. In this work, we discuss mainly surface topography obtained by interferometric and optical properties with special setups.
