Hydrodynamic model for particle beam-driven wakefield in CNT

• Pablo Martín-Luna

Room: Seminar room - ICMUV, University of Valencia Charged particles traveling through a carbon nanotube can excite electromagnetic modes in the electron gas confined within the cylindrical graphene shell that forms the nanotube wall. This mechanism has recently been proposed as a promising approach for short-wavelength, high-gradient particle acceleration. In this work, we revisit the theoretical framework based on a linearized hydrodynamic model describing the response of a single-walled carbon nanotube (SWNT) to a localized point charge. In the model, the electron gas is treated as a plasma, incorporating solid-state effects through additional terms in the momentum equation. The system of governing equations, comprising the continuity and momentum equations, is coupled with Maxwell’s equations, and the resulting differential equations are solved using a modified Fourier-Bessel transform. We analyze the plasma modes capable of generating a longitudinal electric wakefield component suitable for accelerating trailing particles. Numerical simulations are presented to explore how parameters such as the damping factor, the driver velocity, nanotube radius, and particle position affect the excited wakefields. Finally, we assess the strengths and limitations of this theoretical model in capturing the key features of CNT-based acceleration mechanisms.

High-power RF laboratory at IFIC for linear accelerators used in hadrontherapy medical applications

• Pablo Martinez-Reviriego

Room: Seminar room - ICMUV, University of Valencia The High-Power RF Laboratory at IFIC (Instituto de Física Corpuscular) is dedicated to advancing high-gradient radiofrequency (RF) technologies for linear accelerators, with a particular focus on medical applications such as hadrontherapy. This facility enables the development, testing, and conditioning of accelerating structures operating at high electric fields, which are essential for creating compact and efficient linacs suitable for clinical environments. The laboratory supports research on RF breakdown phenomena, field emission, and the optimization of cavity performance under extreme conditions. By addressing the technical challenges associated with high-gradient operation, the IFIC RF Laboratory contributes to the design of next-generation accelerators that can deliver precise and effective cancer treatments, paving the way for broader adoption of hadrontherapy in hospitals.
