The PPM project

The PPM PPM-DOM in Antares (already presented) Tests of the Vertical Electro-Optical cable Deployment of a small scale production model

The VEOC First tests to test oil properties and fibre properties under pressure 430 m half section of VEOC built at Nikhef – Learned a lot – Some things a lot easier than expected – Some harder To be deployed end of October in Atlantic at m (on ship already) – Test of oil property (compression versus depth) – Transmission of fibres at 400+ bar In same cruise deploy m ropes for long term test of Dyneema in sea (2 for 3 months 2 for 1 year)

Making a VEOC

Making a VEOC II

Deployment of Full Length DU with VEOC In March deployment of DUs with VEOC near Malaga 14 days of deployment with 2 LOMS As many as possible deployments and LOM- reloading When successful – Deployment of PPM-DU – Where?

Cable deployment tests All items must be on Texel on Feb 20 Items – 40 spheres + buoys – 2 LOMs – 4 VEOCS – Many compass-tilt-meters – 3 DOMs + VEOC for PPM Pelagia used for deployment near Malaga Simple ROV with camera probably available

Parts DOM for PPM-DU – All parts in hand or to be delivered soon – CLB ready in November (Spain) – Cores Production by rapid prototyping for Hamamatsu tubes in Erlangen – Cooling structures available – Spheres available – Instrumentation available – Power boards available soon (Greece) – Shore station electronics (need volunteer) – PMTs 62 ETEL and many Hamamatsu (>31)

CLB: CURRENT STATUS A completely operational CLB already exists!! Developed by Saclay Based on Virtex 5 Xilinx FPGA KM3NeT day – Bolonia 5 October 2012 – Diego Real9

Batch of 4 CLBs already in production: o Expected data: mid-october o Test to be carry out in Saclay where the IFIC team will be formed by the Saclay experts. Many thanks Saclay! o To be used in the PPM-DU Batch of 8 CLBs to be produced after validation of the first batch: o Test to be carry out in Valencia (Already started the process to install a test bench in Valencia – Saclay will produce a crate for the test bench) o To be used in the different test setups CLB: CURRENT STATUS KM3NeT day - Bolonia 5 October 2012 – Diego Real10

O. Kalekin: KM3NeT DOM at ECAP 11 DOM components Integration tools and mechanical components under designing and production PMT and lens dummies for training Gel Wacker 612 A/B

O. Kalekin: KM3NeT DOM at ECAP 12 Core manufacturing Plastic/foam core: 3D Printing against moulding 1/4 of core will be made at Technical Faculty with 3D jet printer BitsFromBytes: 3DTouch 3D Printer Build area 275x275x201 2,590 Euro Plastic PLA (polylactic acid) 59 Euro/kg TheFutureIs3D: Glacier Steel 3D Printer Build area 406x406x406 $2,700

O. Kalekin: KM3NeT DOM at ECAP 13 PMTs Hamamatsu 80mm diameter R PMT 6+25 PMTs have been tested at ECAP and Nikhef TTS(sigma) < 2ns (all) Dark rate < 1kHz (5 of 6) QE at 470nm > 20% (5 of 6) Next bunch of 50 PMT is expected to be Nikhef this/next week

Lots of work Also lots of progress now and in the coming months If anyone wants to join the deployment campaign – let us know 28 October-8 November --- Atlantic campaign 20 Feb – delivery of parts on Texel 1 – 15 March – Cable deployment tests 16 March – Deployment of PPM
