Description
Particle acceleration in plasmas relies on characterization of the medium's density and temperature, determining key plasma parameters (such as plasma frequency, Debye length, Debye number, and coupling parameter) that must be carefully controlled for efficient acceleration.The plasma production in these applications vary, and as a result, the diagnostic techniques used to characterize them also differ significantly. The presentation explore the primary refractometric, interferometric, and spectroscopic methods for measuring plasma density and temperature, tailored to specific experimental setups.In fact,plasmas for particle acceleration can be generated by focusing an intense laser pulse onto a gas jet, a thin or thick foil, or through an electric discharge within a capillary filled with gas at an appropriate pressure. We aim to apply these diagnostic techniques at I-LUCE (INFN-Laser indUCEd Radiation Production) at Istituito Nazionale di Fisica Nucleare-Laboratori Nazionali Sud (INFN-LNS) in Catania, Italy. This facility provides an ideal setting for exploring plasma acceleration methods, offering advanced laser systems and experimental setups to produce plasmas through various techniques. By adapting refractometric, interferometric, and spectroscopic diagnostics to the unique conditions at I-LUCE, we seek to enhance the precision of plasma characterizations and optimize acceleration processes, contributing to the development of more effective plasma-based acceleration systems.
