Electromagnetic Simulation and Design of a Novel Waveguide RF Wien Filter for Electric Dipole Moment Measurements of Protons and Deuterons
J. Slim, R. Gebel, D. Heberling +12
The conventional Wien filter is a device with orthogonal static magnetic and electric fields, often used for velocity separation of charged particles. Here we describe the electrom…
Eliminating beam-induced depolarizing effects in the hydrogen jet target for high-precision proton beam polarimetry at the Electron-Ion Collider
F. Rathmann, A. Nass, K. O. Eyser +16
We analyze beam-induced depolarizing effects in the hydrogen jet target (HJET) at the Relativistic Heavy Ion Collider (RHIC) that has been used for absolute hadron beam polarimetry…
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…
A Universal Method to Generate Hyperpolarisation in Beams and Samples
R. Engels, T. El-Kordy, N. Faatz +12
Sizable hyperpolarisation, i.e. an imbalance of the occupation numbers of nuclear spins in a sample deviating from thermal equilibrium, is needed in various fields of science. For…
Spin decoherence and off-resonance behavior of radiofrequency-driven spin rotations in storage rings
N. N. Nikolaev, F. Rathmann, J. Slim +60
Radiofrequency-driven resonant spin rotators are routinely used as standard instruments in polarization experiments in particle and nuclear physics. Maintaining the continuous exac…
Pilot bunch and co-magnetometry of polarized particles stored in a ring
J. Slim, F. Rathmann, A. Andres +60
In polarization experiments at storage rings, one of the challenges is to maintain the spin-resonance condition of a radio-frequency spin rotator with the spin-precessions of the o…
