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.

Along the upgrade program of ECRH system in GAMMA10, the gyrotron of 500kW level at 28GHz has been developed. The first 500kW gyrotron delivered 500kW at the windows and contributed to produce high ion confining potential. During the operation, it is found that there were some points to be improved: 1) Saturation level of output is smaller than expected. 2) Body current is large. 3) Beam over current occurs frequently. The second gyrotron was redesigned to improve these three points for stable operation. The second one has been changed in the design of internal mode converter, the shape of structure in collector and the slope of internal top roof of the collector. As a Result of 3 improved points, the maximum output power increased from 516kW to 570 kW, body current decreased from 5mA to 2mA, and the rate of beam over current decreased from 7% to 4%.
