Analytic Derivation of Vertical Chromaticity in the Fermilab Muon Storage Ring
Eremey Valetov, Kyoko Makino, Martin Berz
We derive the vertical chromaticity of the Fermilab Muon g-2 storage ring in closed analytic form. Expanding the Hamiltonian as a Taylor polynomial in the dynamical variables…
Beam-Based Diagnostics of Electric Guide Fields and Lattice Parameters for Run-1 of the Muon g-2 Storage Ring at Fermilab
David Tarazona, Martin Berz, Jason Crnkovic +6
A portion of the Muon g-2 Storage Ring electric system, which provides vertical beam focusing, exhibited an unexpected time dependence that produced a characteristic evolution of t…
Accurate Taylor transfer maps for large aperture iron dominated magnets used in charged particle separators and spectrometers
E. Kazantseva, O. Boine-Frankenheim, H. Weick +2
For high-resolution separators like the projected Super-FRS at FAIR, an adapted and accurate ion-optical model considering realistic B-dependent magnet parameters is crucial in ach…
Feasibility Study for an EDM Storage Ring
F. Abusaif, A. Aggarwal, A. Aksentev +92
This project exploits charged particles confined as a storage ring beam (proton, deuteron, possibly He) to search for an intrinsic electric dipole moment (EDM, ) aligne…
Hybrid Methods for Muon Accelerator Simulations with Ionization Cooling
Josiah Kunz, Pavel Snopok, Martin Berz +1
Muon ionization cooling involves passing particles through solid or liquid absorbers. Careful simulations are required to design muon cooling channels. New features have been devel…
Direct Calculation of the Transfer Map of Electrostatic Deflectors, and Comparison with the Codes COSY INFINITY and GIOS
Eremey Valetov, Martin Berz, Kyoko Makino
COSY INFINITY uses a beamline coordinate system with a Frenet-Serret frame relative to the reference particle, and calculates differential algebra-valued transfer maps by integrati…
New method for a continuous determination of the spin tune in storage rings and implications for precision experiments
D. Eversmann, V. Hejny, F. Hinder +98
A new method to determine the spin tune is described and tested. In an ideal planar magnetic ring, the spin tune - defined as the number of spin precessions per turn - is given by…
A Storage Ring Experiment to Detect a Proton Electric Dipole Moment
V. Anastassopoulos, S. Andrianov, R. Baartman +88
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of cm by using polarized "magic" momentum ~GeV/c pr…
CW high intensity non-scaling FFAG proton drivers
C. Johnstone, M. Berz, K. Makino +1
Accelerators are playing increasingly important roles in basic science, technology, and medicine including nuclear power, industrial irradiation, material science, and neutrino pro…
