The progress of research going on in Group of Rare Isotope Beam Physics (RIB), Experimental Physics ResearchCenter, in 2014 is in the following three aspects.1. Detector construction for the Dark Matter Particle Explorer (DAMPE) project. DAMPE is a large spacetelescope aimed at the evidence of dark matter existence through the measurements of their decay products. It isa part of the "Strategic Priority Research Program" of the Chinese Academy of Sciences for space science, and willbe launched in 2015. In this project, the RIB group is involved in the design and construction of the plastic scintillatorFig. 1 (color online) Accumulative adsorp-tion capacity of uranium from brine.detector array (PSD), which is a key component of theload with an active area of 0.8 m 0.8 m.
