Forum on Tracking Detector Mechanics

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 "weak modes" of the system, in-situ adjustments, sensors including load sensors
• Pipe materials, pipe connection techniques and fittings
• Shock and vibration issues such as bond wire vibration during transport and in operation
• Effects on mechanics during fast discharge of magnet coils
• Tracker to beam-pipe interfaces and bakeout scenarios
• Failure management: What do we do to achieve a tracker with maximum duty cycle
• Service management: What strategies do we have to deal with services? How can we minimise installation and testing times?
• Radiation and mechanics: A discussion about the impacts of radiation on the design, materials and also issues like access constraints
• Maintenance scenarios and the required special tooling
• FEA and its comparison to real objects
