Abstract Neutronics studies for a solid target have been done with Monte Carlo high-energy particle transport code NMTC/JAM, when the proton beam with high kinetic energy bombards the target. The effect of the main parameters of the target on the neutron flux is discussed to optimize the target, which will be used for the concept design of the target of spallation neutron source. A target with its aspect ratio 1.5:1 or 2:1 gives the highest neutron flux. Tungsten is the most acceptable material from the technical and economical points of view. Beryllium as a moderating reflector can increase the neutron flux effectively.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
