Based on the notion that local dark-matter field of axions or axionlike particles (ALPs) in our Galaxy induces oscillating couplings to spins nucleons and nuclei (via electric dipole moment latter and/or paramagnetic axion-wind effect), we establish feasibility a new method search for ALPs storage rings. previous work allows us maintain in-plane polarization stored deuteron beam few hundred seconds, perform first proof-of-principle experiment at Cooler Synchrotron (COSY) scan momenta near...
This paper presents the successful application of a phase-lock feedback system to maintain resonance condition radio frequency (rf) spin rotator (specifically, an rf Wien filter) with respect 120 kHz precession in Cooler Synchrotron (COSY) storage ring. Real-time monitoring and filter signal allows relative phase between two be stabilized at arbitrary setpoint. The compensates for deviations by adjusting and/or as needed. With this method, variation demand standard deviation...
High-frequency driven resonant spin rotators are routinely used as standard instruments in polarization experiments particle and nuclear physics. Maintaining the continuous exact parametric resonance condition of equality rotator precession frequency during operation is one challenges. We present a detailed analytical description effects detuning on precessing vertical in-plane components polarization. An important part formalism presented here consideration experimentally relevant...

In polarization experiments at storage rings, one of the challenges is to maintain spin-resonance condition a radio-frequency spin rotator with spin-precessions orbiting particles. Time-dependent variations magnetic fields ring elements lead unwanted precession frequency. We report here on solution this problem by shielding (or masking) bunches stored in from high-frequency rotator, so that masked pilot bunch acts as co-magnetometer for other signal bunch, tracking fluctuations time scale...
