Foundation of Three-Dimensional Spiral Beam Injection Using Canonical Angular Momentum and Symplectic Eigen-Modes
Hiromi Iinuma
Aiming for high injection efficiency in three-dimensional spiral injection, the underlying physical principles governing beam formation and matching should be systematically organi…
First Experimental Demonstration of Beam Storage by Three-Dimensional Spiral Injection Scheme for Ultra-Compact Storage Rings
R. Matsushita, H. Iinuma, S. Ohsawa +6
Three-dimensional spiral injection enables beam storage in ultra-compact rings with nanosecond revolution periods. We report first storage of a electron bea…
Three-Dimensional Spiral Beam Injection:Design Principles and Experimental Verification
Hiromi Iinuma, Ryota Matsushita, Muhammad Abdul Rehman +3
A proof of principle experiment of Three-dimensional spiral beam injection scheme has been carried out. This injection scheme requires a strongly x-y coupled beam to meet magnetic…
Acceleration of positive muons by a radio-frequency cavity
S. Aritome, K. Futatsukawa, H. Hara +52
Acceleration of positive muons from thermal energy to keV has been demonstrated. Thermal muons were generated by resonant multi-photon ionization of muonium atoms emitted fro…
Compact buncher cavity for muons accelerated by a radio-frequency quadrupole
M. Otani, Y. Sue, K. Futatsukawa +11
A buncher cavity has been developed for the muons accelerated by a radio-frequency quadrupole linac (RFQ). The buncher cavity is designed for at an operational frequen…
First muon acceleration using a radio frequency accelerator
S. Bae, H. Choi, S. Choi +23
Muons have been accelerated by using a radio frequency accelerator for the first time. Negative muonium atoms (Mu), which are bound states of positive muons () and two ele…
