Riassunto
La tesi riguarda la progettazione meccanica, l’analisi strutturale e la validazione sperimentale di un purity monitor per argon liquido basato su una sorgente radioattiva di 207Bi. È stato studiato un prototipo a tre detector, usato esclusivamente per scopo di test e validazione. Sono state condotte analisi termo–meccaniche per verificare la robustezza del design in condizioni criogeniche in modo da poter trasportare le soluzioni progettuali adottate sul prodotto finito. Sono stati progettati supporti dedicati per i test ai Laboratori INFN di Legnaro e al CERN, interfacciandosi con l’officina per la produzione. I test hanno verificato stabilità meccanica, rumore elettronico e funzionamento HV e hanno portato all'ottimizzazione delle lunghezze di drift del purity monitor.
The thesis focuses on the mechanical design, structural analysis, and experimental validation of a liquid-argon purity monitor based on a
207Bi radioactive source. A three-detector prototype was studied, used exclusively for testing and validation purposes. Thermo-mechanical analyses were performed to verify the robustness of the design under cryogenic conditions, enabling the transfer of the adopted engineering solutions to the final product. Dedicated support structures were designed for tests at the INFN Legnaro Laboratories and at CERN, in collaboration with the mechanical workshop for their fabrication. The tests verified mechanical stability, electronic noise behaviour, and HV operation, and allowed comparison of different drift lengths, contributing to the definition of the two optimal lengths for the final DUNE purity monitors.
