A
critical parameter for accelerator applications, including colliders and
radiation generation, is the beam third-moment, which is a function of beam
asymmetries, beam position, and emittance. A
high-precision beam third-moment monitor requires accurate beam position and
emittance measurements, while a high-precision emittance measurement requires
precise beam position measurement. At
present, no method exists for the non-destructive, pulse-to-pulse, simultaneous
measurement of beam position, emittance, and third-moment.
This project will develop a high precision cavity-based system for these
simultaneous measurements, without beam interception and without moving parts.
Phase I will provide analysis, and conceptual design of the resonant
cavity system for the simultaneous beam position, emittance, and third-moment
measurements. The system will be
analyzed for magnetic lattice and cavity-derived systematic errors to determine
figures of merit for achievable beam position, beam-size, emittance, and third
moment resolution.
Commercial
Applications and Other Benefits as described by the awardee:
The high precision integrated measurement technique for in-line,
non-destructive, pulse-to-pulse, measurement of beam position, emittance, and
third-moment should be applicable to any particle accelerator where maintaining
beam quality is crucial, from high energy physics accelerators to medical
application accelerators. Other
possible uses include other linacs, and Free Electron Lasers.
