Contributions to a conference proceedings

Research and development of an accelerator-based THz source prototype for pump-probe experiments at the European XFEL are ongoing at the Photo Injector Test Facility at DESY in Zeuthen (PITZ). Proof-of-principle experiments have been performed to generate a high-gain THz Free-electron Laser (FEL) based on the Self-Amplified Spontaneous Emission scheme. [...]

We introduce Reality Fusion, a novel robot teleoperation system that localizes, streams, projects, and merges a typical onboard depth sensor with a photorealistic, high resolution, high framerate, and wide FoV rendering of the complex remote environment represented as 3D Gaussian splats (3DGS). Our framework enables robust egocentric and exocentric robot teleoperation in immersive VR, with the 3DGS effectively extending spatial information of a depth sensor with limited FoV and balancing the trade-off between data streaming costs and data visual quality [...]

Femtosecond Laser Irradiation followed by Chemical Etching is exploited to create microfluidic devices for High-order Harmonic Generation (HHG) in noble gases. A finetuning of the channels’ diameter and length permits the production of high-order harmonics in completely different regimes, going from the hollow waveguiding regime to the sub-mm interaction regime. [...]

This paper investigates the application of redirected walking techniques in the context of a virtual reality (VR) telepresence system designed for remote control of a maintenance robot within hazardous environments. We estimate detection thresholds for curvature gains in two distinct environments: a 360-degree video-based VR setup and a three-dimensional (3D) modeled environment. [...]

Real-world industrial facilities often present complex equipment that requires extensive inspection and maintenance for their operations. In this work, we present a virtual reality (VR) framework that supports virtual facility inspection and maintenance tasks by using neural radiance fields (NeRF) models to replicate, store, and visualize the appearance of complex industrial facilities. [...]

The secondary beam production target at future positron sources at the Continuous Electron Beam Accelerator Facility (CEBAF), the International Linear Collider (ILC) or the Future Circular Collider (FCC), features unprecedented mechanical and thermal stresses which may compromise sustainable and reliable operation. Candidate materials are required to possess high melting temperature together with excellent thermal conductivity, elasticity and radiation hardness properties. [...]

Topological defects can play an important role in cosmology. In this short contribution I will discuss a less explored effect that arises in the context of first order phase transitions, by which defects can act as impurities catalysing the decay of the false vacuum. [...]

High-precision timing is vital in space communication for tasks like navigation, data transfer, and coordinating satellite constellations. Currently, ground segments rely on microwave clocks, but emerging optical clocks and links offer great improvements in resolution, precision, and stability for next generation systems. [...]

The high-voltage modulators of the 26 klystrons in the XFEL represent the largest power consumer of the accelerator facility. The beam energy is usually 14 GeV, but a few weeks a year, lower and higher beam energies are also produced. [...]
