In ARMS, the AXUV detector with 20 segments usually used as UV monitor is utilized as the particle detector. Two ARMSs, which are installed with perpendicular and tangential views are operated for measuring the real time neutral particle distribution and investigating the particle loss.}, title = {Perpendicular and tangential angularly resolved multi-sight neutral particle analyzer system in LHD}, volume = {Vol.83}, year = {2012} }
