An Induction-Type Septum Magnet for the Hadron and Electron Injection of the EIC Complex

The design of the electron Ion Collider (EIC) project is under way to be built at the Brookhaven National Laboratory (BNL) with the collaboration of the Thomas Jefferson National Accelerator Facility (TJNAF). The Rapid Cycling Synchrotron (RCS) which is part of the EIC accelerator complex will accelerate the electron beam up to 18 GeV, and the beam will be injected into the Electron Storage Ring (ESR) to collide with the hadron beam circulating in the Hadron Storage Ring (HSR) which is a modified version of the Relativistic Heavy Ion Collider (RHIC). All three synchrotrons will be located in the same tunnel. This technical note provides information on the latest electromagnetic design of the induction-type septum magnet which will be employed by EIC to Inject the beam into the HSR and RCS and also extract the beam from the RCS.

The EIC accelerator: design highlights and project status

The design of the electron-ion collider (EIC) at Brookhaven National Laboratory is well underway, aiming at a peak electron-proton luminosity of 10e+34 cm^-1·sec^-1. This high luminosity, the wide center-of-mass energy range from 29 to 141 GeV (e-p) and the high level of polarization require innovative solutions to maximize the performance of the machine, which makes the EIC one of the most challenging accelerator projects to date. The complexity of the EIC will be discussed, and the project status and plans will be presented.

Progress on the normal conducting magnets for the Electron-Ion Collider

The electron-ion collider (EIC) at Brookhaven National Laboratory (BNL) is designed to deliver a peak luminosity of 1e+34 1/cm2 1/sec. The EIC will take advantage of the existing Relativistic Heavy Ion Collider (RHIC) facility. Two additional rings will be installed: an electron storage ring (ESR) and a rapid cycling electron synchrotron ring (RCS).This paper presents an update on the normal conducting magnet designs required for both the ESR and RCS rings. The ESR will store polarized electron beams up to 18 GeV and utilizes a triplet of dipole magnets to increase the emittance at 5 GeV and generate excess bending to create additional radiation damping to allow a larger beam-beam tune shift. The RCS will accelerate single bunches of spin-polarized electrons at various energies from 5 GeV to 18 GeV, with a ramp rate of 100 ms and 1 Hz repetition rate. Both rings require dipole, quadrupole and sextupole magnets with different specifications.
