The development of high energy neutral particle measurement system for ion temperature measurements and high energy particle confinement analysis in Large Helical Device is described here. For NBIs, 180 keV hydrogen beams will be used in Phase 1 of LHD experiment schedule and 360 keV deuterium beams will be used in Phase 2. In ICRF heating experiment, the hydrogen and helium-3 will be used as minorities. It is important to observe the pitch angle distribution to investigate the confinement of high energy particles. For this purpose the neutral particle analyzer should have a wide observation energy range above the maximum energy of NBI and an ability to separate the particle species of hydrogen, deuterium and He-3. In Compact Helical System (CHS), the electrostatic neutral particle analyzer is used. They have compared the spectrum obtained from the measurement by a passive method in CHS with that from the calculation by PROCTR code.
