Ziel von openCost ist die Schaffung einer technischen Infrastruktur, mit der Publikationskosten über standardisierte Schnittstellen und Formate frei zugänglich abgerufen werden können. So soll eine Kostentransparenz auf institutioneller, nationaler und internationaler Ebene ermöglicht werden. [...]

Effects of carbon and nitrogen concentrations on precipitation sequence duringtempering of martensitic steels investigated by advanced experimental methodsand modelingJ. Teixeira, M [...]

Synchrotron-radiation phase-contrast tomography is a non-invasive technique that allows high-resolution imaging of soft structures. We present the first results of the cochlea (inner ear) of a harbor porpoise (Phocoena phocoena). [...]

Imaging anatomical features of the human brain at cellular resolution currently relies on series of physical sections with related slicing artefacts. So far, microtomography has been employed to image an entire human brain at a voxel size of 20µm and selected regions using 6µm. [...]

High-resolution synchrotron x-ray computed tomography (CT) in situ pull-out tests with stepwise increased loading were performed to investigate the force transfer between a shape memory alloy (SMA) wire and the surrounding epoxy polymer matrix. The advancing interfacial failure was observed. [...]

Future High Duty Cycle (HDC) operation scenarios of the European X-ray Free Electron Laser (EuXFEL) promise increased bunch repetition rate and photon delivery, at the cost of changing system requirements and moving away from the current mode of Short Pulse (SP) operation. To assess whether the third harmonic cryomodule design is also suitable for Long Pulse (LP) and Continuous Wave (CW) operation, key parameters of the spare module are examined at the Accelerator Module Test Facility (AMTF).

We demonstrate a high-power tunable laser based on a CMOS-compatible power-amplifier. We show amplified power up to 1.8 W with a tunability bandwidth of 60 nm from 1.83 µm to 1.89 µm, limited only by the seed laser [...]

We demonstrate high power tunable laser using a CMOS-compatible integrated LMA power amplifier. We show amplified power up to 1.5 W from around 100 mW of input seed power in the wavelength window spanning from 1800 to 1900 nm..

We demonstrate a widely tunable laser amplified to high power with a CMOS-compatible integrated LMA power amplifier. We show amplified power up to 1.5 W from around 100 mW of input seed power in the wavelength window spanning from 1800 to 1900 nm

Precisely calibrating RF superconducting radio-frequency linear accelerators is crucial for accurately assessing cavity bandwidth and detuning, which provides valuable insights into cavity performance, facilitates optimal accelerator operation, and enables effective fault detection and diagnosis. In practice, however, calibration of RF signals can present several challenges, with calibration drift being a significant issue, especially in settings prone to humidity and temperature fluctuations.
