A meeting to discuss issues of engineering and integration for present and future tracking systems.

Topics include

• Detector cooling
• Deflection, stability and precision of the structures, achieved and revisited requirements for the next generation
• Thermal expansion differences inside the detector
• Mass and therefore radiation length of mechanics, cables and pipes
• Humidity control, including gas flushing inside detector volume and along services
• Structural issues concerning humidity or outgassing
• Choices of construction materials
• Rails for support and guidance
• Alignment systems, requirements and
