Beam Tilt Signals as Emittance Diagnostic in the Next Linear Collider Main Linac

Technical Report ·
DOI:https://doi.org/10.2172/799104· OSTI ID:799104

High frequency cavity beam position monitors (BPMs) can also provide information on the xz or yz correlation of the beam (yaw or pitch, respectively). Such a diagnostic is particularly desirable in the Next Linear Collider (NLC) main linacs, where the principal sources of emittance dilution generate such a correlation. Test results from the extremely low emittance beam at the KEK Accelerator Test Facility (ATF) [1] are described. The formalism of beam-tilt signal generation and detection are reviewed, and studies of possible emittance correction schemes based on the beam tilt signals are presented.
