LARP, through SLAC, is participating fully in the Phase II Collimation project as outlined in the CERN White Paper plan and any action on LARPs part that looks, as this does, like it is circumventing the agreed to schedule damages our relationship with our colleagues and is doomed to failure.
If, after the R&D process concludes in October 2010, a decision is made to produce some number of rotatable copper collimators, SLAC is ready to participate.
This exercise should only be taken at the CD-0 level: mission need and ballpark cost estimate, and is hopefully, laying the bureaucratic groundwork for eventual US participation in construction of collimators
