Japan Proton Accelerator Research Complex (J-PARC) aims at a MW-class proton
accelerator facility. One of the promising solutions for increasing the beam
power of the Main Ring (MR) is converters of the main magnets with new ones for
this upgrade....

The betatron tune, which is defined as the number of transverse oscillations
in one turn of a ring accelerator, is one of the most important parameters. An
undesired betatron tune increases the amplitude of the transverse oscillation
so that many ...
