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.

Electron cyclotron current drive (ECCD) experiments carried out in the TJ-II stellarator are presented. In all the analyzed plasma discharges, the second-harmonic electron cyclotron resonance heating (ECRH) power is launched on-axis from two low-field-side stellarator symmetric positions. To investigate the ECCD properties of the device, the dependence of the total toroidal plasma current on the launching direction of both ECRH beams at fixed density conditions, and on the line average density for some fixed launching configurations, has been determined. In the launching direction scan, only discharges with similar density and temperature profiles have been studied, in order to avoid strong modifications of the bootstrap current contribution and the refraction properties of the plasma. Moreover, the measurements of the toroidal plasma current and the plasma profiles are taken at the end of the discharge, when approximately steady-state conditions are achieved. Using the normalized current drive efficiency as defined by ECCD [identical] <ne> IECCDR/PECRH, we have obtained values up to ECCD [approximately equal to] 0.001 × 1020 A W-1 m-2.
