Thomson scattering (TS) is widely applied in the field of high-temperature plasma diagnostics for highly localized measurements of the electron temperature and density in the plasma. Two multipoint TS diagnostics with high spatial resolution, one focused on the core plasma and one on the edge plasma, are being developed on the COMPASS tokamak. TS on COMPASS is based on a set of two Nd:YAG lasers (1064 nm, 30 Hz, and 1.5 J each), two objectives collecting the light from both the core and edge plasma regions and number of polychromators equipped by Avalanche photodiodes and spectral filters. Both conceptual and detailed designs of most parts of the diagnostic as well as procurement phase were finished in 2009. In this paper, progress in development of TS, focusing on assembling and testing of particular items, is summarized. The detailed description of port plug structure and unique design of collection objective are given for both the core and the edge TS diagnostics.
