Abstract

In this work we present the test run results for the electron cooling system at the Booster synchrotron, which were conducted at the Nuclotron-based Ion Collider facility (NICA) injection complex in 2020–2023. We have demonstrated a successful cooling of the 56Fe14+ and 124Xe28+ ion beams at the injection energy 3.2 MeV/u. In this work, we provide parameters of the ion and electron beams, as well as a detailed description of the tuning procedures used for the e-cooling system during the experiments.

Notes

  1. In the expression (1) mi is average mass of the nucleus taking into account the not stripped electrons. For the 124Xe28+ ion it is mi = 930.787 MeV/u.

  2. During the experiments with 124Xe28+ energy was measured base on the revolution frequency and was found at 3.203 Mev/u.
