Measurement of spin motions in a storage ring outside the stable polarization direction.

چکیده
Polarized, stored beams are becoming a more and more important tool in nuclear and high energy physics. In order to measure the beam polarization in a storage ring the polarization vector of the stored, beam has to aim, revolution for revolution, over a period of seconds to minutes, into the same, so-called “stable”, direction. In this paper measurements at the Indiana University Cooler Ring (IUCF) are described in which for the first time in a storage ring oscillations of the polarization vector around this stable direction have been measured [l]. The existence and the dynamics of such oscillations are, for instance, important for a new proposed technique for polarizing stored hadron beams [2].

The Phase Space Dependent Spin Polarization Direction in the Hera Proton Ring at High Energy
In very high energy storage rings the equilibrium spin polarization direction can vary strongly from point to point in phase space. Thus, unless counter measures are taken, the average polarization of the beam can be seriously limited. In this paper we present estimates of this limitation for the HERA proton ring as a function of beam energy and other system parameters, and discuss methods to m...
متن کاملSpin-Flipping Polarized Deuterons At COSY
We recently stored a 1.85 GeV/c vertically polarized deuteron beam in the COSY Ring in Jtilich; we then spin-flipped it by ramping a new air-core rf dipole's frequency through an rfinduced spin resonance to manipulate the polarization direction of the deuteron beam. We first experimentally determined the resonance's frequency and set the dipole's rf voltage to its maximum; then we varied its fr...
متن کاملTracking algorithm for the stable spin polarization field in storage rings using stroboscopic averaging.
Polarized protons have never been accelerated to more than about 25GeV. To achieve polarized proton beams in RHIC (250GeV), HERA (820GeV), and the TEVATRON (900GeV), ideas and techniques new to accelerator physics are needed. In this publication we will stress an important aspect of very high energy polarized proton beams, namely the fact that the equilibrium polarization direction can vary sub...
متن کاملLongitudinally Polarized Colliding Beams
The feasibility of experiments with the polarized colliding beams expands significantly possibilities of getting information on fundamental interactions. Even the use of the transversely polarized beams enables getting the more reliable and clear definition of spins for the intermediate states and final particles,1p2 as well as to introduce the precise absolute energy scale.3-s But only the use...
متن کاملSearch for Electric Dipole Moments with Polarized Beams in Storage Rings
An electric dipole aligned along the spin axis of a fundamental particle, nucleus, or atomic system violates both parity conservation and time reversal invariance. The observation of such a phenomenon would, at present or proposed levels of experimental sensitivity, signal new physics beyond the Standard Model. The usual method for identifying an electric dipole moment (EDM) in such searches is...
