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…
Scale invariance of electrodynamics in radio-frequency linear accelerators
Osamu Kamigaito
This study discusses the scale transformation of electromagnetic fields and trajectories of ions in radio-frequency linear accelerators. We will obtain a condition for mechanical s…
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…
