AD&I Meeting: Parameters and options for reduced power

Friday 23 Jul 2010, 15:00 → 16:45 Europe/Berlin

ilc.webex.com

Ewan Paterson (SLAC), Nicholas Walker (DESY)

This meeting will focus on the possible options for reduced beam power operation, including discussions on possible 'upgrade scenarios' to restore the full number of (nominal RDR) bunches. In addition we will discuss further the range of IP beam parameters, with a goal of agreeing on tentative sets of physics relevant parameters (from 200-500 Ecm) for further study.
