WGA:Beam Dynamics in Rings

Invited Oral Presentation

A detailed study on random resonances was conducted to facilitate further beam power ramp-up in the 3-GeV rapid cycling synchrotron of the Japan Proton Accelerator Research Complex. Systematic experiments employing a low-intensity beam revealed considerable excitation of the 2nd-order random resonances, namely horizontal half-integer and linear sum resonances, located just above the current...

117. Recent optics measurements and corrections for high-intensity operation of the J-PARC Main Ring (TUIAB03)

WGA:Beam Dynamics in Rings

Invited Oral Presentation

In the intensity-frontier proton synchrotron J-PARC Main Ring (MR), a power upgrade plan is underway to achieve 1.3 MW beam power for neutrino experiments. The upgrade has generally progressed as planned, with the beam power for the user operation reaching 830 kW as of May 2025. A major obstacle to upgrading the beam power of the MR is the radioactivation of accelerator components caused by...

185. Recent developments of the TRIUMF 520 MeV cyclotron in support of high intensity operation (TUIAB04)

WGA:Beam Dynamics in Rings

Invited Oral Presentation

The TRIUMF 520 MeV cyclotron continues to serve as a reliable driver for high-intensity proton beams, supporting a broad range of applications. To sustain and enhance high intensity operation, recent developments have focused on reducing beam losses and improving overall reliability. This talk will highlight progress in several key areas: upgrades to the new injection beamlines; cyclotron tune...
