| 11:00 - 12:00 Journal Club: Experiment & Phenomenology – meeting Beam Loading Studies in Positron Source Capture Linac of Compact Linear Collider (CLIC) School PARTICLES AND ACCELERATORS Abstract: The production of intense high-quality positrons for R&D in high-energy physics colliders and other applications, is achieved using GeV-energy electrons impinging on a hybrid tungsten target. The positrons emerge from the target with a large momentum spread and at not-relativistic energies, and they have to be accelerated rapidly in order to be transported to the next stages of the accelerator. The CLIC positron source consists of a hybrid target, an adiabatic matching device and a capture Linac. The parameters of these devices influence strongly the final useable positron yield. In the tracking simulations, a ... 14:00 - 15:00 Weekly Seminar Plasmonic 2D Materials: Overview, Recent Progress, and Future Prospects School NANO SCIENCES In recent years, major experimental and theoretical efforts were made to explore the optical and transport properties of two-dimensional (2D) crystalline materials. Two-dimensional materials are characterized by highly confined, low-loss, and tunable plasmon polaritons, making them an ideal platform for exploring different regimes of light-matter interactions. One of the remarkable subjects is hyperbolic plasmons in novel 2D materials because of their highly confined and tunable nature, e.g., using chemical doping, gating, or strain. Recently, promising hyperbolic two-dimensional plasmon polaritons have been discovered for the first time in e ... |
