IST FY08 R&D Prototyping 2 APV25-S1 Carbon-Carbon CF Ladder FY08 IST prototype module PHOBOS IV sensors PrePrototype Kapton hybrid-cable 2 Gerrit van Nieuwenhuizen

IST FY08 prototype top view 3 Gerrit van Nieuwenhuizen

IST 'FY08' prototype side view 4 Gerrit van Nieuwenhuizen

IST FY08 prototype hybrid I 1 meter long for prototype This part folds underneath the ladder 5 Gerrit van Nieuwenhuizen

IST FY08 prototype hybrid II 1/2mil K + 1mil Glue + 17um Cu + 1mil K + 1mil Glue + 1/2mil K → 0.07 %Xo + 0.12 %Xo → ~ 0.2 %Xo 6 Gerrit van Nieuwenhuizen

IST FY08 prototype C-C substrate 7 Gerrit van Nieuwenhuizen

IST Readout Chips 100 APV25-S1 Readout Chips need to be procured from Imperial College ---> Funds are available, OK BUT, we also want to secure ALL chips needed for both FGT and IST → Will try to do this through FGT construction funds = lower overhead! → Should happen before end of July? → Gerrit will pick them up in London? 8 Gerrit van Nieuwenhuizen

Bonding machine and Probe station Hughes wire bonder has been serviced and put back on service contract Test bonding with 0.8 mil Al wire was successful Test bonding on kapton is under way Alessi automatic probe station is, for the most part, functional again No service contract possible, but it is a simple machine and we have 2 New controlling PC is being connected 9 Gerrit van Nieuwenhuizen

IST pre-prototype module Bonding feasibility and cable/hybrid prototype Bonding machine has been serviced, needs some setup time Proof of principle that we can bond on Kapton When finished needs to be tested with old readout system 10 Gerrit van Nieuwenhuizen

IST FY08 prototype sensors 10 PHOBOS Inner Vertex sensors have arrived from UIC IV probing has been done Some PN test keys done → Full Depletion Voltage Capacitance and Pinhole scan of all channels have to wait until probestation has been equiped with PC again Most important is the leakage current of active area and guard, we don't care too much about individual broken channels for a prototype 11 Gerrit van Nieuwenhuizen

IST FY08 prototype sensors IV tests OK OK? OK OK 12 Gerrit van Nieuwenhuizen

IST FY08 Ladders (and Mounting)‏ When the size of the hybrid is fixed Make ladder design similar to ATLAS upgrade staves → Jim & Gerrit Have a prototype ladder produced by LBNL → Eric Anderson 13 Gerrit van Nieuwenhuizen

IST FY09 R&D production prototype 14 Gerrit van Nieuwenhuizen

IST FY09 R&D Hamamatsu sensors I 15 Gerrit van Nieuwenhuizen

IST FY09 R&D Hamamatsu sensors III ~$500k for production sensors ~$110k for FY09 R&D prototypes 16 Gerrit van Nieuwenhuizen

IST Conceptual Design Report 17 Gerrit van Nieuwenhuizen

IST Conclusions MIT-LNS Silicon facility for 80% operational again Prototype silicon sensors acquired Readout chips will be ordered soon Kapton hybrid/cable feasible, will be ordered next week Carbon-Carbon substrate will be ordered next week Ladder request to Eric will go out next week Prototypes ready end of October 2008 Hamamatsu quote within budget Working on CDR 18 Gerrit van Nieuwenhuizen
