TL;DR: In this article, a single-source X-ray transmission and Compton scattering security check device in an L-shaped structure is described, which is low in price, quick in detection speed, high in sensitivity, capable of detecting different types of prohibited goods such as metal weapons, explosive, and narcotics simultaneously.

TL;DR: In this paper, a storage method for centralized extensible fusion type multi-dimensional complex structure relational data is proposed, which is suitable for storing, analyzing and managing the large, medium and small-scale complex data of the enterprises, providing effective data with quality assurance for the user-oriented enterprise-level big data integration platforms, and providing an extensible and usable data storage and access technology.

TL;DR: In this article, a 2D moving sample stage in vacuum chamber is used to precisely position points to be analyzed in target, and synchronously starting spectrum acquisition when the sample stage is located at the measurement point and saving the corresponding spectrum when the acquisition is finished by utilizing the job control script of ORTEC MAESTRO software.

TL;DR: In this article, a U-shaped unisource X-ray transmission and compton scattering safety inspection device is proposed. But the design of the detector array is not discussed.
