Near term actions • Cost estimation: • removal of components from the PEP-II tunnel. • packaging the components into shipping containers (steel shipping boxes) • transportation costs to Italy • Storage costs in Italy • Two to four Italian engineers are coming to SLAC in late February (week of Feb 23) to discuss the task and shipping arrangements. • DOE formal review of PEP-II Minimum Maintenance state (MMS) and Disposal and Dispersal (D&D) March 23-24, 2009 at SLAC. Super-B Orsay Meeting
PEP-II Hardware Conclusions • The present Super-B design uses many of the PEP-II components. • By weight and numbers, most of the Super-B requests can be fulfilled if the project goes ahead. • If other projects do not go ahead, then Super-B could get additional components, primarily injection components. • Engineers are studying removal, shipping, planning and costing. • DOE review of PEP-II MMS and D&D in late March 2009.
