Status of the experiment on magnetic field reversal at BINP

The paper describes experiment devoted to the field reversal in a mirror trap with neutral beam injection, which is planned for realization now in Budker Institute. The technical details of experimental device and expected plasma parameters are discussed. In accordance with theoretical predictions, parameters of experimental facility (neutral beam current − 240 atom A, energy of neutrals − 15 keV, magnetic field − 0.2 T, electron temperature 50 eV and target plasma density ∼1013−1014 cm−3) are expected to be sufficient to field reversal in the case, if anomalous ion losses are not essential.
