Title: Simulations of space charge neutralization in a magnetized electron cooler

Abstract

Magnetized electron cooling at relativistic energies and Ampere scale current is essential to achieve the proposed ion luminosities in a future electron-ion collider (EIC). Neutralization of the space charge in such a cooler can significantly increase the magnetized dynamic friction and, hence, the cooling rate. The Warp framework is being used to simulate magnetized electron beam dynamics during and after the build-up of neutralizing ions, via ionization of residual gas in the cooler. The design follows previous experiments at Fermilab as a verification case. We also discuss the relevance to EIC designs.

  • This paper presents an experimental and analytical description of IEMP produced with electron beams. Time-dependent measurements are reported of the radial distribution of the current transmitted across a 12-inch-diameter cylindrical cavity, as a function of air pressure within the cavity, for two types of electron pulses--a short pulse of 4 kA peak, 30-nsec FWHM, and a long pulse of 10 kA peak, 100-nsec FWHM. Measurements of the injected beam parameters are also reported, including a determination of the spectrum of the emitted electrons as a function of time, using a simple magnetic spectrometer. DYNACYL calculations of transmitted current as amore » function of air pressure for the short-electron-pulse case are summarized. The DYNACYL calculations give a qualitative description of the transmitted current time history, in most cases agreeing within a factor of 2 with the experimental data. Discrepancies are thought, in some instances, to be due to inaccurate specification of the injected beam parameters, as well as to the simplifications employed in the computer code.« less
  • Non-magnetized electron cooling of RHIC requires an electron beam energy of 54.3 MeV, electron charge per bunch of 5 nC, normalized rms beam emittance of 4 mm-mrad, and rms energy spread of 4e-04 [I]. In this paper we describe a lattice of a two-pass SRF energy recovery linac (ERL) and results of a PARMELA simulation that provides electron beam parameters satisfying RHIC electron cooling requirements.
  • It is shown by numerical simulations that in a collisionless plasma electron inertia leads to inefficient neutralization of positive space charge and allows large positive potentials ({phi}{much gt}{ital kT}{sub {ital e}}/{ital e}) to be established and maintained on the time scale of ion motion. This is true even if the buildup of positive space charge is so slow that it corresponds to a small fraction of the random electron current of the surrounding plasma. A simple physical model clarifies the physics of the process and provides an analytical expression for the potential.
  • A study is made of space charge and current neutralization injection of a relativistic electron beam into a plasma-filled waveguide which is bounded in the longitudinal direction. The beam density is assumed small in comparison with the plasma density, so that the beam current can be assumed to be given. A strong longitudinal magnetic field is imposed on the system to prevent transverse spreading of the beam. The nature of the neutralization is strongly affected by the reflection from the ends of the system and the interference of the oscillatory fields induced by the beam. These changes are not takenmore » into account in models with an infintely long drift tube.« less
