PPMs  The Pre-Production Models are deliverables of KM3NeT-PP PPM of the optical module PPM of the calibration system PPM of the readout/DAQ system PPM of a ‘small scale’ detection unit Final deliverable: description of the Production Models 

PPM-objectives Questions to be answered with these PPMs: Can we deploy? Can we calibrate? Can we measure signals? Can we get the signals to shore? Can we measure muon signals? What do we learn for the PM? December 2010: Report delivered to EC describing the PPM models (KM3NeT_FL_REP_PPM_description)

PPM 20 storeys, 6m bars, for DU distance of 180m 2 storeys with ‘active’ DOMs To be deployed and connected at….?

PPM-PMTunit: ‘mini-DOM’ in ANTARES Objective: Measurement of singles rates and coincidences with 3” PMTs Delivery of info for simulation software and PMT specs for tendering Implementation: 5 PMTs only (limited by ANTARES readout) Integration of mini-DOM in ANTARES instrumentation line

PPM-DOM: ‘full’ DOM in ANTARES Objective Long term benchmark of DOM Test of KM3NeT readout electronics Delivery of Production Models for DOM, calibration, readout/DAQ, transmission network Implementation: Install a DOM in Instrumentation Line of ANTARES Adapt optical data transmission to ANTARES network

PPM-DU mechanics and deployment Objective Test of deployment and unfurling of full detection unit Test of handling of backbone cable during deployment and unfurling Delivery of Production Models of DU mechanics Delivery of Production Model of backbone Implementation Several test deployments with smaller DU models Test deployments with 20 storey DU model

PPM-DU backbone Objective Implementation Test of handling of backbone cable during deployment and unfurling Test of penetrators Delivery of Production Models of backbone Implementation Shallow water tests with backbone unfurling Install backbone with autonomous fibre monitoring devices on 20 storey DU If possible, use Delta Berenike for deployment/recovery

PPM-Operation: ‘mini-tower’ at Capo Passero site Objectives Test of KM3NeT fibre optics and data transmission network Test of detector operation Delivery of Production Modules of all components (update) Implementation Install 3 DOMs (two with ETEL, one with Hamamatsu PMTs) Install ‘active’ backbone cables Install ‘active’ storey cables Connect to the existing seabed infrastructure and use the shore station facilities at the Capo Passero site
