MC6.T03 Beam Diagnostics and Instrumentation

Contributed Oral Presentation

This work presents techniques for non-invasive transverse profile measurements of high-intensity proton beams using an Electron Beam Profile Scanner (EBPS). The EBPS utilizes low-energy electrons as a probe to analyze the transverse size of proton beams, allowing for potential analysis on a single-bunch basis. Recent upgrades to the Fermilab Main Injector have enhanced beam power on target to...

1247. Data-driven hysteresis compensation in the CERN SPS main magnets (WEAN2)

MC6.D13 Machine Learning

Contributed Oral Presentation

Magnetic hysteresis and eddy current decay continue to challenge beam quality and operational consistency in multi-cycling machines like the Super Proton Synchrotron (SPS) at CERN. Building on our previous work, this paper presents improvements in the data-driven approach for magnetic field modelling to enhance the reproducibility of SPS dipole and quadrupole fields and thus maintain stable...

521. Supersonic gas curtain-based in-vivo transverse beam profile monitoring for medical accelerators (WEAN3)

MC6.A28 Medical Applications

Contributed Oral Presentation

To ensure patient safety, treatment effectiveness, and facility efficiency, each ion beam therapy facility requires a complete online characterization of the charged particle beam. Existing dosimetry methods are either limited in the information they provide or invasive to the beam, highlighting the need for new in-vivo dosimetry solutions. Since 2015, the QUASAR Group at the Cockcroft...

1609. Machine learning-based orbit correction in the RCS of CSNS

Xiaohan Lu (Institute of High Energy Physics)

MC6.D13 Machine Learning

The rapid cycling synchrotron (RCS) of The China Spallation Neutron Source (CSNS) accumulates and accelerates the injection beam from 80 MeV/300 MeV to the energy of 1.6 GeV and then extracts the high energy beam to the target. During each cycle of the RCS ring, beam positions at the same BPM vary over time due to energy and mode transitions. Traditional orbit correction averages turn-by-turn...
