The BT access has yet to be negotiated, and there has been no commitment yet to individuals or groups. The actual percentages have to be negotiated. Submission of peer-reviewed proposals would not be required for each assignment of beamtime. The important principle is still peer review. PIs need national funding and thus their projects already have been peer reviewed.
Flexibility is needed without a lot of paperwork.
This is similar to 3. I think that the CLS still has to have its own peer review system. The system of allocation will be an open one and will be available to all. By the way, an eight page document on preferred and priority access has been drafted, and will be discussed by the BPAC in its early June meeting. Combined with the three new clauses referred to above, a lot of these issues will become clearer.
