First testsFirst testsFirst testsFirst tests
•8 TimePix chips have been connected on the PCB
- issues for the wire bonding
two chips were broken by the bonding factory
•Electrical test- an error of routing was found and corrected using external wires
- power supply by MUROS only was insufficient (0.2 A per puce)
3 voltage to stabalize (LV) to 2.2V

Tests with 2 chipsTests with 2 chipsTests with 2 chipsTests with 2 chips
•The 8 chips were removed and replaced by only two
•New test at CERN (January 20th, 2009)- the hardware was validated- but, correction needed in the official software Pixelman

•A new card was designed taking into account what we learn with the previous
•New design : - the 2x4 matrix is place on top a mezzanine to make easier the wire bonding- power regulators was implemented
•Waiting for Ingrid
•Should be tested on the Large Prototype TPC by the end of this year or beginning of next year

• QUAD chips board tested OK in 2008
• Equiped with Ingrids in June ‘09
•Could become standalone “traveling” TA infrastructure
•within RELAXD project: 4x4 Medipix chips in compact mounting
•will evolve in 8x8 Timepix chips for EUDET

Ingrid production statusIngrid production statusIngrid production statusIngrid production status
Several single chip systems produced for:
•Test detector performance with different thickness of Si3N4 protection layers (in DESY T22 beam)
•Test efficiency and resolution in Gossip-like geometry (only 1.5 mm gas layers) in CERN testbeam
- Data analysis in progress- Sometimes still discharges that kill Timepix chips;
some indication it is on the ‘outside’ edges of Ingrid/Timepix

ConclusionsConclusionsConclusionsConclusions
•The electrical tests of the first board were helpful
•Waiting for Ingrids to equip the new board when it will be ready
•Next step: install and test it in the LP1 (2010)
•Studies in parallel with RELAXED project/Gossip at NIKHEF
