I'm not sure. It's possibly either the space between beam-clearing slits or jaws (to scrape off divergent particles) or the distance between beam-monitoring coils/squids/whatever. TOTEM I could understand, they move their detectors in close to the beam, but LHCb I'm far less familiar with. On Page1 the P2 and P8 would refer to "point 2" and "point 8" -- see the map of sector temperatures at cern.ch/lhc -- point 8 is LHCb and point 2 is the ALICE experiment. Ah, a bit of googling shows that they must be jaws, somehow TDI means "LHC injection beam stopper", probably in French... http://lhc-impedance.web.cern.ch/lhc-impedance/LHC_equipments.htm#TDI Some nice engineering drawings for you... Oops, just dumped beam. -- Ivan Reid, School of Engineering & Design, _____________ CMS Collaboration, Brunel University.

Oh right. When you put it like that it is so clear. -- steve auvache VN750 Third gear has scope. SR250 The SpazzTrakka (Improved).
