英文摘要	A newly developed limiter Langmuir probe (LLP) array has been applied to the scrape-off layer (SOL) plasma measurement in EAST tokamak. The LLP system consists of two poloidal arrays located at opposite sides of the low field side guard limiter, and each poloidal array has 26 Langmuir probe channels with a spatial resolution of 35 mm in the vertical direction. The probe tip is polished to match the local graphite tile plane and avoid the leading edge and the corresponding high heat load. The probe can be assembled easily and has an excellent electric insulating property. Langmuir probes have three operation modes, i.e., floating potential mode, ion saturation current mode, and swept Langmuir probe mode. The LLP array could be operated in different modes according to the experimental purpose. The LLP array has been successfully applied to the EAST experiment in 2021, and the three-dimensional plasma structure and the plasma parameters (electron density and temperature) in the SOL have been measured.
