Peter Woit provides this link to a talk at CERN
http://indico.cern.ch/getFile.py/ac...onId=6&resId=1&materialId=slides&confId=22937
Slide 46 indicates that restart will not occur until late summer 2009 (Plan A) or sometime in 2010 (Plan B)
The talk was given today by Jörg Wenninger.
Wenninger's slides are well-illustrated with photos and diagrams, including labeled shots of the components where problems developed, and provide the clearest explanation which I have seen so far of the unfortunate event in section 34 of the ring.
By way of summary, here's what slide 46 says:
==quote==
Plans for 2009
Plan A:
• Restart in (late) summer of 2009 beam with beam.
• Beam intensity and energy limited to minimize any risk.
Plan B:
• No beam before a complete ‘upgrade’ of the pressure-relief system is
implemented sectors on all sectors.
• Excludes beam in 2009.
Final decision in February?
46
==endquote==
So we may know in February, if a decision is made about completing the upgrade and scheduling restart.
