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...
In 2010, based on the superconducting heavy-ion synchrotron Nuclotron, a new accelerating complex NICA (Nuclotron-based Ion Collider fAcility) started to be constructed at Laboratory of High Energy Physics Joint Institute for Nuclear Research, its key facility being 1.0 - 4.5 GeV per nucleon heavy ion collider. For purpose effectively collecting statistics, an average collider luminosity cms is required. With this energy, cooling beam both in process storage and during experiment mandatory...
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...
Stochastic cooling is obligatory for the NICA accelerator facility that presently under development at JINR, Russia. Cooling will work with high-intensity bunched beams in 3-4.5 GeV energy range; all three dimensions be treated simultaneously. The preparatory experimental on stochastic carried out Nuclotron (JINR) since 2010. During this hardware solutions and automation techniques system adjustment have been worked tested. Based gained experience overall design of was also developed. report...
Nuclotron-based Ion Collider fAcility (NICA) is the new accelerator complex being constructed in Joint Institute for Nuclear Research. General goal of project to provide experimental study hot and dense strongly interacting QCD matter [1]. The development NICA injection actively performed. Construction 3.2 MeV/u heavy-ion linear (HILac) now under way Germany. Booster synchrotron has been started. New results stochastic cooling experiments achieved at Nuclotron are great practical interest...
Radiofrequency-driven resonant spin rotators are routinely used as standard instruments in polarization experiments particle and nuclear physics. Maintaining the continuous exact parametric spin-resonance condition of equality rotator precession frequency during operation constitutes one challenges. We present a detailed analytic description impact detuning resonance on vertical in-plane precessing components polarization. An important part formalism presented here is consideration...
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...
The unique global feature of COSY is its ability to accelerate, store and manipulate polarized proton deuteron beams. In the recent past, these beams have been used primarily for precision measurements, in particular connection with study charged particle EDMs (Electric Dipole Moment) storage rings. role as a R&D facility initial (static oscillating) EDM measurements can hardly be overestimated. Unfortunately, consequence strategic decisions Forschungszentrum Jülich subsequent...
