Conveners

Instrumentation and machine aspects related to luminosity calibration

• Helmut Burkhardt (CERN)

Description

• overview/expectations of machine/beam properties
• review state-of-the art and/or novel technologies for beam current normalisation (for LHC-like beams), including experience from other hadron colliders
• review methods/possibilites to determine the beam current fraction that does not contribute to luminosity (for LHC-like beams)
• review intermediate b* options for 2011
