Mechanic development
Tools conception for “automated” manufacturing
Precise alignment of the different parts of the modules:
silicon strips pitch adapter connectivity FEE
Perfect integration on the carbon fiber support during the gluing
Analogical video camera
Suction system with micro metric screw
System tolerance

Mechanic development Faraday cage (I.Villa and V.Saveliev)
Two reference sensors equipped with the VA1' chip
Example of configuration:
Sensors equipped with SiTr130-88 chip
Collimator for alignment study
Possibility to do a “standalone” tracking + EUDET tracking
October 6th-8th, 2008 Alexandre [email protected] 15
Data Acquisition System
Flexible system: work with VA1 chip, SiTr130-88 (A.Comerma, H.PHAM, R.Sefri), and future
Idea: develop a DAQ, can work in EUDET environnement or on standalone for local test
Easy upgradable system → FPGA board with USB output/input
Real tool box to automatize the different study: pedestal, calibration, alignment etc ....

Data Acquisition System
Hardware parts
FPGA board with USB connexion (A.Comerma) – VHDL code to manage (M.Dhellot, A.Charpy):
SiTr-130 and FEE acquisition for tracking VA1 acquisition for reference tracking
October 6th-8th, 2008 Alexandre [email protected] 17
Data Acquisition System
Software parts
Slow control is managed by Labview code (J.F.Huppert)
DAQ system is written in C++ and using the Root framework (C.Ciobanu, A.Charpy):
Set the DAQ system and chip configurations
Written the raw data Possibility of on-line
monitoring Send the data to EUDET
DAQ system if needed
October 6th-8th, 2008 Alexandre [email protected] 18
Data Acquisition System
Software parts DAQ system is written in C++ and using the Root framework (C.Ciobanu, A.Charpy):
XML Documentation generated by Doxygen (Activity diagram, time diagram)
Universal raw data format
Unified the control command for the DAQ system
Possibility of on-line monitoring
Send the data to EUDET DAQ system if needed

Summary Mechanical status
Tools are ready to produce the module sensors
Availability for EUDET collaboration → Need to know new specification for tool customization or if changes is needed
DAQ status VHDL and C++ code is under development (will be ready for the
next testbeam)
Next step: SiTr130 management
Next tasks Validation of the DAQ system
Behaviour study of the electronics and sensors with local tests
Characterization of the new SiTr130-88 chips → beam test @ DESY in March 2009
