Vibrating wire for beam profile scanning [PDF]
Physical Review Special Topics. Accelerators and Beams, 1999 A method that measures the transverse profile (emittance) of the bunch by detecting radiation arising at the scattering of the bunch on scanning wire is widely used. In this work information about bunch scattering is obtained by measuring the oscillation

Beam Position Projection Algorithms in Proton Pencil Beam Scanning. [PDF]
Cancers (Basel)Beam position uncertainties along the beam trajectory arise from the accelerator, beamline, and scanning magnets (SMs). They can be monitored in real time, e.g., through strip ionization chambers (ICs), and treatments can be paused if needed. Delivery is more reliable and accurate if the beam position is projected from monitored nozzle parameters to ...

Novel Beam Scan Method of Fabry–Perot Cavity (FPC) Antennas
Applied Sciences, 2021 A new beam scanning method of a Fabry–Perot cavity (FPC) antenna is proposed. To obtain high gain in a target direction with a reduced sidelobe level (SLL), we devised a tapered partially reflective surface (PRS) as a superstrate.
