slide5

IST FY08 prototype hybrid I

1 meter long for prototype

This part folds underneath the ladder

slide6

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

slide8

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?

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

slide10

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

slide11

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

slide12

IST FY08 prototype sensors IV tests

OK

OK?

OK

OK

slide13

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

slide16

IST FY09 R&D Hamamatsu sensors III

~$500k for production sensors

~$110k for FY09 R&D prototypes

slide18

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
