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…
Cross sections of mesons in collisions at forward rapidity at GeV and central rapidity at GeV
PHENIX Collaboration, N. J. Abdulameer, U. Acharya +497
We present the first measurements of the forward and midrapidity -meson cross sections from collisions at and ~GeV, respectively. We also report t…
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…
Centrality dependence of Lévy-stable two-pion Bose-Einstein correlations in GeV AuAu collisions
PHENIX Collaboration, N. J. Abdulameer, U. Acharya +394
The PHENIX experiment measured the centrality dependence of two-pion Bose-Einstein correlation functions in ~GeV AuAu collisions at the Relativistic Heavy…
