Forum on Tracking Detector Mechanics, CERN 3-4 July 2012


This is the first announcement for the 'Forum on Tracking Detector Mechanics' to be held at CERN, 3-4 July 2012 in the BE Auditorium, Room 6-2-024. It would be a pleasure for us to welcome you at CERN to this event.

 The goal of this forum is an exchange of experience obtained during the design, construction installation of the current LHC tracking detectors. Evaluation of where ample or insufficient emphasis was put, problems encountered as well as excellent solutions found in order to improve performance and reliability of future tracking detectors.


We would appreciate if you could use the online Registration form on the Forum home page:
The forum will be limited to a maximum of 120 participants.

There are no registration fees for the Forum. Refreshments at coffee breaks will be provided but lunches are not included. There will be a charge (around 60 CHF) for the (optional) workshop dinner to be held Tuesday evening, 3 July. Receipts for the dinner fee will be available.

Best Regards, Hans Postema for the Organising Committee.

Please forward this message to interested colleagues!

 Provisional list of topics:

- Cooling issues inside tracker volume
- Supply and return lines inside full detector volume
- Deflection, stability and precision of the structures, achieved and revisited    
   requirements for the next generation
- Detectors, sub-detectors and components must survive transport loads
- Thermal expansion differences inside the detector
- Mass and therefore radiation lengths of electronics
- Mass and radiation lengths of cables and pipes
- Humidity control, inside detector volume and along services
- Gas flushing and gas cooling of tracking detectors
- 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
- Vibration issues such as bond wire vibration (transport, operation)
- Effects on mechanics during fast discharge of magnet coils
- Tracker to beam-pipe interfaces, 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
