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

Low-Cost High-Gain Transmitarray with Beam-Scanning Enhancement Based on Hybrid Phase Distribution Method [PDF]
SensorsIn this paper, a multi-feed transmitarray with high-gain, wide-angle beam-scanning, and low-cost features is presented. A novel hybrid phase distribution (HPD) method is proposed to improve the beam-scanning range by combining the single-focal and ...

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 ...

Luminosity scans for beam diagnostics [PDF]
Physical Review Accelerators and Beams, 2018 A new type of fast luminosity separation scans ("Emittance Scans") was introduced at the CERN Large Hadron Collider (LHC) in 2015. The scans were performed systematically in every fill with full-intensity beams in physics production conditions at the Interaction Point (IP) of the Compact Muon Solenoid (CMS) experiment.

A Wideband Reflectarray Antenna for Satellite Application with Low Cross-Polarization
Applied Sciences, 2023 A double-layer element consisting of a spider-shaped structure on the top layer and a pair of concave arms with a circular ring on the middle layer is proposed for the wideband reflectarray with low cross-polarization characteristics.

Integration of Scanning Probes and Ion Beams [PDF]
Nano Letters, 2005 We report the integration of a scanning force microscope with ion beams. The scanning probe images surface structures non-invasively and aligns the ion beam to regions of interest. The ion beam is transported through a hole in the scanning probe tip. Piezoresistive force sensors allow placement of micromachined cantilevers close to the ion beam lens ...
