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….?

– 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:
