A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

Investigation of the hot initial plasma created in an axisymmetric end system of the ambipolar trap AMBAL-M has been completed. In the end mirror we obtained the MHD stable plasma with the electron temperature of 50 eV, ion temperature 200 eV, and density about 1013 cm−3. In an MHD anchor – the semicusp a transverse profile of the plasma pressure favorable for the MHD stability was obtained. Pulsed injection of fast atoms with the current of 100 A demonstrated sufficient accumulation rate of the ion population trapped into the initial plasma. The first experiments with ICR-heating of the initial plasma were carried out.
Two atomic injectors of the end mirror were prepared for work. In these injectors four quasistationary proton beams were obtained with the energy of 25 keV and current of up to 50 A per beam. After their charge-exchange the atomic beams were passed through an MHD stabilizing shell and the target plasma.
Principal vacuum units of the 2-nd stage of the installation were tested and prepaired for assembly. One-half of the magnet-vacuum system of the AMBAL-M central solenoid was assembled and tested for vacuum.
