Attività prevista (Luglio-prima settimana settembre)
• Questa settimana
Test FCM, chiusura vessel di piano, test Vessel su camera iperbarica
integrazione backbone , break out e PMT su struttura meccanica
• Integrazione piani:
Si parte dal piano piu’ vicino alla base
-collegamento OM-FCM
-collegamento FCM-break out di piano
-test con 4 OM oscurati simile a quello di fase 1 (acquisizione fondo PMT,
misura margine ottico, …..
-si passa al piano successivo
• Test finale
Effettuato oscurando tutta la struttura come se la torre fosse in mare
Si utilizza tutta la on shore electronics
- Trigger System Controller (TSC): monitors and serves the TriDAS - (1 GbE I/O) (to be finalized)
- Hit Managers (HM): receive optical data; prepare and distribute the Time Slice (TS) to the TCPU (DONE)
- TriggerCPUs (TCPU): apply the trigger logics to the assigned TS and transfer the selected data to the EM;
note: more than 1 TCPU process can run on a TCPU server (Quasi done: TriggerAlgos to be finalized)
- Event Manager (EM): receives the triggered data from TCPUs and build the Post-Trigger events data file

Shuttle (INGV standard operation)
MODUS Shuttle power failure.
SN1 released 250 above seabed (1850 m).
SN1 fallen upside down on the seabed
ROV and Certamen C/L Vessel joint operation:
SN1 hooked and turned correctly above the seabed
SN1 connected to the TSN cable
termination. Switch on.

•Stato attuale:
il segnale dei 4 idrofoni e’ ‘affogato’ nel rumore.
•Causa probabile:
Modifiche effettuate per estendere la banda verso
 basse frequenze( 20 Hz) x terremoti e balene.
•Soluzioni possibili
svolgimento cavo connessione
bypassare la JB

Prossime Operazioni
• Test operatività ROV a 3500 m previsto per seconda
metà luglio
• Deployment e connessione torre a Capo Passero
previsto a settembre
Compatibilmente con la slot temporale disponibile ,si
cercherà anche di intervenire sul sistema acustico
