COMPENSATION OF CHROMATICITY IN THE JLEIC ELECTRON COLLIDER RING
Nosochkov, Yuri.
The Jefferson Lab Electron-Ion Collider (JLEIC) is being designed to achieve a high luminosity of up to 10^34 cm^−2s^−1. The latter requires a small beam size at the interaction point demanding a strong final focus (FF) quadrupole system. The strong beam focusing in the FF unavoidably creates a large chromaticity which has to be corrected in order to avoid a severe degradation of momentum acceptance. This has to be done while maintaining sufficient dynamic aperture. An additional req... Show Full Abstract
The Jefferson Lab Electron-Ion Collider (JLEIC) is being designed to achieve a high luminosity of up to 10^34 cm^−2s^−1. The latter requires a small beam size at the interaction point demanding a strong final focus (FF) quadrupole system. The strong beam focusing in the FF unavoidably creates a large chromaticity which has to be corrected in order to avoid a severe degradation of momentum acceptance. This has to be done while maintaining sufficient dynamic aperture. An additional requirement in the electron ring is preservation of a low beam emittance. This paper reviews the development of a chromaticity correction scheme for the electron ring. Show Partial Abstract
