WP3: The Neutrino Factory Costing Status

1. WP3: The Neutrino Factory Costing Status Ajit Kurup CERN Costing Workshop 8th December 2011

2. Introduction • Progress since last workshop. • Go over the PBS and CFPs for each subsystem and outline the key pieces of information needed for the costing (input into spreadsheets for uploading to the Costing Tool), schematic drawings, etc. • Thanks to Neil Bliss and Norbert Collomb for their engineering input. • I will show some slides that Neil prepared. • Norbert will present work being done on the FFAG and decay rings. • Areas where we need additional support. • Future plan.

38. Plan • Work on inputting information into the spreadsheets and the costing tool. • Work out what information (and format) for EDMS. • Get engineering input for the components and pricing. • Write baseline description document and schedule CERN reviews. • June 2012 • Complete design (i.e. no holes) with cost estimates for components. • Costing of all buildings, tunnels and services.
