Description
The evolution of ECR ion sources is driven by the demand for higher charge states, beam intensities and reliability, requiring advances in plasma physics, microwave engineering and superconducting technologies. To support these developments, INFN-LNS is building two research infrastructures: TELAMONES and PANDORA. TELAMONES will host an AISHA source operating at 18 and 21 GHz for beam development, plasma studies and RF/microwave propagation investigations, together with a second setup dedicated to high-intensity beams. PANDORA extends the role of ECR plasmas from ion-beam production to a subject of research itself, aiming at the first measurement of radionuclide β-decay rates in plasma conditions relevant to nuclear astrophysics through a comprehensive online diagnostic system.
During the upgrade of the LNS accelerator complex, the installation of a second AISHa source at CNAO provided a valuable test bench for improving beam availability, reproducibility and maintenance procedures. The experience demonstrated the feasibility of adapting advanced superconducting ECR technology to hospital environments, where reliability and operational continuity are mandatory.
Building on these results, the development of SC-AISHa, a new ECRIS designed for operation up to 28 GHz in High-B mode with enhanced magnetic confinement, is ongoing. This paper presents the current status of TELAMONES and PANDORA and outlines the main research and development activities.
