VI session

Black phosphorus is a unique two-dimensional (2D) material (Figure 1) with a tunable infrared band gap and anisotropic conduction properties [1]. Black phosphorus also displays the occurrence of a pressure-induced topological Lifshitz transition turning the material from a narrow gap semiconductor to a massless Dirac metal due to a nonavoided band crossing [2]. We investigate the ambient...

3. Underway Projects for Innovative THz/IR Sources based on Particle Accelerators: SISSI 2.0 and SABINA

Lorenzo Mosesso (Sapienza, University of Rome, Department of Physics)

VI session

Terahertz/Infrared (THz/IR) radiation and technologies have found incredible development in the last few decades due to their applications in many different fields, ranging from indoor and outdoor communication, security, environmental monitoring, biological research, medical applications and finally as a spectroscopic investigation tool in condensed matter [1]. However, many of these...

7. The LNF IR-THz beamline @ DAϕNE: experimental set-ups and perspectives

Lucilla Pronti (INFN-LNF)

VI session

The INFN-LNF DAϕNE storage ring produces a powerful source of Synchrotron Radiation in the THz range [1]. The brilliance of SR in the THz domain is up to three orders of magnitude with respect to conventional sources (i.e. mercury lamps), as shown in Figure 1, and the flux increases with the electron current stored. These aspects permit to perform experiments in several field from material...

23. Material Characterizations in the Sub-THz Region for Particle Accelerators

Andrea Passarelli (INFN - Sezione di Napoli)

VI session

Coatings play a crucial role for the functionality of vacuum chambers in particle accelerators, serving dual purposes by efficiently facilitating pumping and mitigating electron cloud effects. However, their impact on the surface resistance of chamber walls raises concerns, potentially influencing machine performances and imposing limitations on achievable energies and currents. Therefore, an...
