Titolo della Tesi di Laurea:
L'eta' dei raggi cosmici nel disco galattico
Progetto di Ricerca:
Messa a punto di un programma di simulazione con il metodo Montecarlo per la propagazione dei Raggi Cosmici nel disco galattico. Si sono pertanto calcolate le medie dei tempi di permanenza nel disco e le medie nella cavita' solare con particolare attenzione alla distribuzione delle direzioni, dell'energia e dei tempi medi di arrivo.


Titolo della Tesi di Dottorato:
Studio del rumore termico in regime di stazionarieta' e di non-stazionarieta' per l'interferometro VIRGO
Progetto di Ricerca:
Il rumore termico rappresenta il limite principale per la sensibilita' dell'Interferometro Virgo nell'intervallo di frequenze compreso tra i 5 ed i 500 Hz. In regime di stazionarieta' tale limite puo' essere ridotto scegliendo con accuratezza il materiale e la geometria dell'ultimo stadio di sospensione delle ottiche dell'interferometro. Per tale ragione si e' studiato un tipo di sospensione innovativa rispetto a quella attuale usando fibre di quarzo come elemento di sospensione. Tramite l'uso di una simulazione si e' studiato come ottenere un miglioramento della sensibilita' in regime di non-stazionarieta' usando il rilassamento all'equilibrio termodinamico. Per questo scopo si discute infine la realizzazione nell'immediato futuro di un esperimento.
