Title: Polarization preservation of polarized deuteron beams in the electron ion collider at Brookhaven National Laboratory

Abstract

The physics program at the future electron ion collider (EIC) calls for polarized neutron beams at high energies. The best neutron carriers are ³He nuclei and deuterons. Both neutron carriers are expected to be utilized by the spin physics program in the EIC. Owing to the small magnetic moment anomaly of a deuteron particle, significantly higher magnetic fields are required for spin rotation, so that full Siberian snakes are not feasible. However, the resonance strengths are weak, and the number of resonances is small. It is possible to deal with individual resonances using conventional methods such as a betatron tune jump and vertical ac dipole for intrinsic depolarizing resonances, and a weak partial snake for imperfection resonances. This study employed a realistic magnet ramp rate and parameters (both transverse and longitudinal emittances, as well as realistic lattices) to show that it is possible to accelerate polarized deuterons beyond 100 GeV/n. This paper summarizes the details of the feasibility of a polarized deuteron beam for the future EIC at Brookhaven National Laboratory.

Feasibility of a polarized deuteron beam in the AGS and RHIC

Conference Lee, S Y ; Ratner, L G - AIP Conference Proceedings (American Institute of Physics); (United States)

The possibility of accelerating polarized deuterons in the AGS and RHIC is discussed. In the AGS, the polarized deuteron can be accelerated up to 15 GeV/c without depolarization. In RHIC, the snake designed for use in accelerating polarized protons are applicable as partial snake in inducing spin flip to overcome the imperfection resonances. Gradient error resonances in RHIC are found to be negligible. Difficulties arise from intrinsic resonances in RHIC, which limit the polarized deuteron collision energy to less than {gamma}{le}29 or to energy less than 27.2 GeV/u, if corrections are not made. A type 3 snake is found tomore »« less
RHIC: The World's First High-Energy, Polarized-Proton Collider (423rd Brookhaven Lecture)

Multimedia Bai, Mei

The Relativistic Heavy Ion Collider (RHIC) at BNL has been colliding polarized proton at a beam energy of 100 billion electron volts (GeV) since 2001. In addition to reporting upon the progress of RHIC polarized-proton program, this talk will focus upon the mechanisms that cause the beam to depolarize and the strategies developed to overcome this. As the world first polarized-proton collider, RHIC is designed to collide polarized protons up to an energy of 250 GeV, thereby providing an unique opportunity to measure the contribution made by the gluon to a proton's spin and to study the spin structure ofmore »« less

On multiple Siberian snakes

Technical Report Yokoya, Kaoru

The acceleration of polarized proton beams has been done in a number of synchrotrons such as at ANL, Saclay, BNL, and KEK. The theory and technique have been well established up to the energy of few tens of GeV; however, the same technique cannot be applied to an energy range of TeV as in the SSC. For such a machine we need Siberian snakes. As for this clever scheme, however, nothing is known experimentally and even theoretical knowledge is not enough to make reliable predictions for the SSC. It is generally thought that the single and double Siberian snake schemesmore »« less

RHIC Polarized proton operation

Conference Huang, H ; Ahrens, L ; Alekseev, I G ; ...

The Relativistic Heavy Ion Collider (RHIC) operation as the polarized proton collider presents unique challenges since both luminosity(L) and spin polarization(P) are important. With longitudinally polarized beams at the experiments, the figure of merit is LP{sup 4}. A lot of upgrades and modifications have been made since last polarized proton operation. A 9 MHz rf system is installed to improve longitudinal match at injection and to increase luminosity. The beam dump was upgraded to increase bunch intensity. A vertical survey of RHIC was performed before the run to get better magnet alignment. The orbit control is also improved this year.more »« less

RHIC spin project -- Acceleration of polarized protons

Conference Roser, T

To achieve high energy polarized proton collisions polarized beams first have to be accelerated which requires an understanding of the evolution of spin during acceleration and the tools to control it. The acceleration of polarized beams in circular accelerators is complicated by the presence of numerous depolarizing resonances. During acceleration, a depolarizing resonance is crossed whenever the spin precession frequency equals the frequency with which spin-perturbing magnetic fields are encountered. There are two main types of depolarizing resonances corresponding to the possible sources of such fields: imperfection resonances, which are driven by magnet errors and misalignments, and intrinsic resonances, drivenmore »« less
