Abstract:

In order to fully grasp the technical composition and development tendency of the collider, this paper analyzes the patents and papers related to the collider technology in the past 30 years. The statistics on the annual, national, and institutional distributions of the patents and paper are presented firstly. Then, this study uses the Context-LDA model and LDA topic models to study the topic compositions and hot topics of patents and papers respectively. Further, by using similarity index (JS distance) and information entropy, this study analyzes the topic evolution of papers. The results show that Japan and the United States are the countries with the highest amount of patents and papers respectively. China ranks in the forefront and the output of achievements has increased rapidly in recent years; electrode circuits of accelerated system, beam injection, superconducting devices, vacuum systems, radio frequency chambers, etc., are the most popular topics of the patents. The technical topics of papers related to the Large Hadron Collider have been hot topics at different times. Among them, the hot topics include magnets and solenoids, trace systems, beam cavities, superconducting magnets, calorimeters, etc.. Research topics in the field of collider technology are developing towards a more balanced and diversified trend. This paper recommends that China continues to increase the number of output in this field, increases the research and development (R&D) efforts of hot technology fields; scientific research institutions should seek R&D cooperation with superior enterprises, or promote the integrated development of production, education and research, and speed up the research to determine the construction of a large-scale collider.
