Innovation in research
Advanced accelerator beam diagnostics are essential for user facilities that require intense proton beams with small emittances and high reliability.
Important to have noninvasive diagnostics that can be used continuously with intense accelerated beams.
Determination of particle distributions within an RF bunch is one of the most difficult tasks of all.
Muons, Inc. Ribbon Electron Beam Profile Monitor (RPBM) For Bunched Beam Tomography can address the challenges.
The detailed measurements enabled by the REPBM are important for optimizing high intensity beam accumulation and acceleration and for suppressing instabilities in order to increase beam luminosity and lifetime. The facilities that this will impact are:
Edge view of the strip cathode electron gun showing the simulation of ribbon electron beam extraction, acceleration, and focusing by the deflector plates (extraction voltage Uex=10 kV, Accelerating voltage Ua=100 kV, focusing voltage on the deflector system is Uf=-5 kV). Red lines are electron trajectories, green lines are equipotentials. The scale is 1 mm/division.
