\begin{abstract}
The RFX-mod experiment, now evolving into RFX-mod2, is an operational magnetically confined plasma physics experiment, located at Consorzio RFX premises, focused on studying the physics of fusion plasmas and magnetic confinement in Reversed Field Pinch (RFP) configuration.
The increasing demand for high-performance remote desktop solutions, capable of handling graphics-intensive applications and modern user interfaces, has exposed the limitations of existing Virtual Desktop Infrastructure (VDI). Traditional VDI systems often struggle with latency, resource utilization, and providing a fluid user experience, especially when running on Linux-based environments.
During the experiment, several significant improvements were made to the experimental setup, including mechanical modifications, updates to the electrical configuration, and enhancements to the CODAS (Control, Data Access, and Communication Systems). These changes, designed to increase the efficiency and reliability of the machine, will also provide researchers with an increasing amount of diagnostics, opening a view of the plasma phenomena with an unprecedented level of detail. This comes with a new challenge of handling such a large amount of data.
This thesis presents the design and implementation of a novel VDI solution that addresses these challenges by leveraging a modern technology stack. The proposed system features a Wayland-native Remote Desktop Protocol (RDP) gateway, designed to provide low-latency, hardware-accelerated remote sessions. By using Wayland, the system benefits from its enhanced security model and improved performance over the legacy X11 display server.
This thesis presents the implementation of a unified platform to streamline experimental data access and documentation. The primary objective is to facilitate advanced data analytics by integrating a web-based application for managing semantic information from the experiment logbook with a query engine for efficient scientific data access. By providing a more accessible and integrated framework for data analysis, this unified system aims to improve the efficiency and reliability of the overall research workflow.
A core innovation of this work is the use of Open Container Initiative (OCI) containers to encapsulate user sessions. This containerization layer provides strong isolation between sessions, enhances security, and allows for dynamic and efficient resource allocation. Each user session runs in a dedicated container, ensuring that applications have their own isolated environment, which prevents conflicts and improves system stability.

This thesis details the architecture of the Wayland RDP gateway, the integration with the containerization layer, and the implementation of hardware acceleration to offload graphics rendering to the GPU. The performance of the system is evaluated through a series of benchmarks, measuring CPU and GPU usage, video playback performance, latency, and network throughput. The results demonstrate the viability of the proposed solution as a high-performance, scalable, and secure VDI platform for modern Linux desktops.

L'esperimento RFX-mod, attualmente in evoluzione nella configurazione RFX-mod2, è un impianto operativo di fisica del plasma a confinamento magnetico situato presso il Consorzio RFX, che ha come obiettivo principale lo studio della fisica dei plasmi da fusione e il confinamento magnetico in configurazione Reversed Field Pinch (RFP).
Nel corso dell'esperimento sono stati apportati numerosi miglioramenti significativi alle modalità di sperimentazione, tra cui interventi di natura meccanica, aggiornamenti dell'impianto elettrico e miglioramenti del sistema CODAS (Control, Data Access, e Communication Systems). Questi interventi, mirati ad aumentare l'efficienza e l'affidabilità del sistema sperimentale, aiuteranno anche i ricercatori a ottenere una quantità maggiore di strumenti diagnostici, permettendo loro di osservare i fenomeni relativi al plasma con un livello di dettaglio senza precedenti. Ciò comporta però una nuova sfida: la gestione di elevate quantità di dati di natura eterogenea.
Questa tesi tratta l'implementazione di una piattaforma unificata per la semplificazione dell'accesso ai dati sperimentali e alla documentazione. L'obiettivo principale è quello di facilitare l'analisi avanzata dei dati, integrando in un unico sistema: una applicazione web per la gestione delle informazioni semantiche provenienti dal logbook sperimentale e un motore di estrapolazione efficiente dei dati scientifici. Con la creazione di un framework più accessibile e integrato per l'analisi dei dati, questo sistema unificato mira a migliorare l'efficienza e l'affidabilità dell'intero flusso di lavoro della ricerca.
