Characterization of silicon pore optics for the NewAthena X-ray observatory in the PTB laboratory at BESSY II.

The New Advanced Telescope for High ENergy Astrophysics (NewAthena) will be the largest space-based X-ray observatory ever built. It will have an effective area above 1.1 m at 1 keV, which corresponds to a polished mirror surface of about 300 m due to the grazing incidence.

Clinical outcomes in a U.S. registration study of a new EDOF intraocular lens with a nondiffractive design.

Purpose: To evaluate the effectiveness and safety of the DFT015 intraocular lens (IOL) (AcrySof IQ Vivity Extended Vision) compared with an aspheric monofocal control IOL (AcrySof IQ model SN60WF).

Setting: 11 investigation sites in the U.S.

Characterization of a quadrant diamond transmission X-ray detector including a precise determination of the mean electron-hole pair creation energy.

Precise monitoring of the incoming photon flux is crucial for many experiments using synchrotron radiation. For photon energies above a few keV, thin semiconductor photodiodes can be operated in transmission for this purpose. Diamond is a particularly attractive material as a result of its low absorption.

Clinical and patient-reported outcomes of bilateral implantation of a +2.5 diopter multifocal intraocular lens.

Purpose: To assess the effectiveness and safety of a multifocal intraocular lens (IOL) with +2.5 diopter (D) additional power compared with a monofocal IOL.

Setting: Fifteen sites in the United States.

Photoelectric-enhanced radiation therapy with quasi-monochromatic computed tomography.

Photoelectric-enhanced radiation therapy is a bimodal therapy, consisting of the administration of highly radiation-absorbing substances into the tumor area and localized regional irradiation with orthovoltage x-rays. Irradiation can be performed by a modified computed tomography (CT) unit equipped with an additional x-ray optical module which converts the polychromatic, fan-shaped CT beam into a monochromatized and focused beam for energy-tuned photoelectric-enhanced radiotherapy. A dedicated x-ray optical module designed for spatial collimation, focusing, and monochromatization was mounted at the exit of the x-ray tube of a clinical CT unit.
