Abstract The spontaneous and the stimulated radiations, as well as the relationship between them, are calculated for an electron moving in the wiggler with the independent magnetostatic-field on the axial (z) coordinates. It is shown that the Madey's law is still valid in the novel wiggler case. The small signal gain of free-clectron laser is calculated in a novel wiggler.

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.
