	We present updates of a simulation suite to model in-plasma ion-electron dynamics, including self-consistent electromagnetic (EM) wave propagation and ion population kinetics to study atomic processes in ECR plasmas. The EM absorption is modelled by a heuristic collisional term in the cold dielectric tensor. However, we are stepping beyond the cold approximation, modelling the hot tensor with non-collisional RF wave damping. The tool calculates steady-state particle distributions via a full wave-PIC code and solves for collisional-radiative process giving atomic population and charge state distribution. The scheme is general and applicable to many physics’ cases of interest for the ECRIS community, including the build-up of the charge-state-distribution and the plasma emitted X-ray and optical radiation. We present its last updates and future perspectives, using as a case-study the PANDORA scenario. We report about studying in-plasma dynamics of injected metallic species and radioisotopes ionisation efficiency for different injection conditions and plasma parameters. The code is capable of reconstructing space-resolved plasma emissivity, to be directly compared to plasma emission measurements, and modelling plasma-induced modification of radioactivity.

TUD2	A novel test-facility for ECRIS plasma diagnostics: optical spectroscopy, X-ray imaging and spectroscopy, mm-wave polarimetry

	In the frame of the PANDORA project and the SAMOTHRACE ecosystem (Italian PNRR in the EU Next Gen Program contest), two new plasma diagnostics testbenches – PYN-HO and VESPRI2.0 setups – have been developed at INFN-LNS, with the aim to design and improve detectors and techniques beyond the state of art. The PYN-HO prototype is conceived to operate in four configurations: two of them to enhance high resolution X-ray imaging and space-resolved spectroscopy, also including X-ray tomography using multi pin-hole CCD systems, involving algorithms for Single Photon-Counted and High-Dynamic-Range analysis, with related calibrations via SDD; the other two are dedicated to high energy resolution diffractometric spectroscopic measurement in the X-ray and optical domains, based on micrometric gratings. The VESPRI2.0 mm-wave polarimeter is based on an innovative superheterodyne approach to measure plasma-induced Faraday rotation from Lissajous figure detection and estimate the plasma line-integrated density. Prototypes can be installed in ECRIS for several plasma physics studies [4], such as investigations of plasma structure, confinement dynamics, instabilities and turbulence, in-plasma and plasma vessel elemental composition, local thermodynamic parameters, etc. which are directly related to ion beam performances in ECRIS. The design and features of the prototypes and the first characterizations performed with Ar plasma in the INFN-LNS Flexible Plasma Trap will be presented. [1] D.

In this framework, there is a growing interest in the availability of mA beams of singly charged (1+) metallic ions to realise quantum devices. To satisfy this request, the joint INFN Laboratories LNS and LNL proposed to modify the Flexible Plasma Trap (FPT), installed at LNS, thus transforming it into a simple mirror Electron Cyclotron Resonance Ion Source (ECRIS). This contribution describes the various technical solutions that will be adopted, foreseeing novel radial RF and gas/metal injection systems, focusing particularly on the design and simulations of a flexible extraction system capable of handling different beam intensities and ion species. Specifically, the project targets the production of high-intensity beams of singly charged ions such as Fe⁺, and Ba⁺, highlighting the versatility and innovation of the proposed modifications.

THA2	Numerical design of an innovative superconducting magnetic trap for probing β-decay in ECR plasmas	159

	The main aim of Plasmas for Astrophysics Nuclear Decays Observation and Radiation for Archaeometry (PANDORA) project is to build a flexible magnetic plasma trap where plasma reaches a density nₑ ∼ 10¹¹ – 10¹³ cm⁻³, and a temperature, in units of kT, kTₑ ∼ 0.1 – 30 keV in order to measure, for the first time, nuclear β-decay rates in stellar-like conditions. Here we present the numerical design of the PANDORA magnetic system, carried out by using the commercial simulators OPERA and CST Studio Suite. In particular, we discuss the design choices taken to: 1) obtain the required magnetic field levels at relevant axial and radial positions; 2) avoid the magnetic branches along the plasma chamber wall; 3) find the optimal position for the set of plasma diagnostics that will be employed. The magnetic trap has been conceived to be as large as possible, both in radial and axial directions, in order to exploit the plasma confinement mechanism on a bigger plasmoid volume. The plasma chamber will have a length of 700 mm and a diameter of 280 mm. The magnetic trap tender procedure has been completed in June 2024 and the structure realization is expected to start in late 2024.
