• Delphi:– Quality control on sensors and modules, Assembly of Pixel and

Outer Barrel modules (Update ’97)• CDF II – ISL:

– Sensor Prototype evaluation– Quality control, Assembly fixture design and construction

• CMS– Prototyping (sensor & modules)– Definition of QA procedure, Design of sensors– Material Analysis– Long term Testing– Irradiation– Definition of QA procedure for modules

• Dedicated pinhole test, beam dump test, current/noise correlations …

– Bonding– Integration– Detector Control & Safety System

• SLHC – Design of new Sensors, evaluation– Radiation hardness studies
