Space-charge compensation of a low-energy He2+ beam with fluorine-containing gases

Takashi Nagatomo, Yasuyuki Morita, Osamu Kamigaito

This study investigates the space-charge compensation (SCC) of a low-energy He2+ beam by introducing fluorine-containing gases into the low-energy beam transport line (LEBT) of the…

Topological aspects of zero modes in cavity resonators

Osamu Kamigaito

We discuss the relationship between the zero modes of electromagnetic fields in a cavity resonator and the cavity's topological characteristics. We show that the dimension of the e…

Nondestructive beam envelope measurements using beam position monitors for low-beta heavy ion beams in superconducting linear accelerator

Takahiro Nishi, Tamaki Watanabe, Taihei Adachi +4

In superconducting linear accelerators (linacs), accurately monitoring beam dynamics is essential for minimizing beam losses and ensuring stable operations. However, destructive di…

J-PARC MUSE H-line optimization for the g-2 and MuHFS experiments

A. Toyoda, Y. Fujiwara, Y. Fukao +12

Significant deviation of the anomalous magnetic moment value (g-2) observed by the muon g-2 experiment should be confirmed by the other experiment. This value is experimentally det…
