This report discusses the development of high energy neutral particle measurement system for ion temperature measurements and high energy particle confinement analysis in Large Helical Device (LHD). In Compact Helical System (CHS), the electrostatic neutral particle analyzer is used. The spectrum obtained from the measurement by a passive method in CHS are compared with that from the calculation by PROCTR code. At the energy range below 1 keV, neutral contribution from the plasma boundary is too large due to the large background neutral density and large charge exchange cross section. The fast neutral spectrum from the calculation agreed well with those from the measurement in CHS.
