Scintillator probes to measure lost fast ions, such as alpha particles, from confined plasmas in LHD by using image intensified charge coupled device camera (LIP-ICCD) or photomultiplier arrays (LIP-PMT-PXI)

Branched signals, such as density, temperature, heating-related and spectroscopic signals, are especially grouped and acquired for LHD's Steady-State Operation (SSO) using ICRF heating

Gas fueling (Gas Puff) system to supply hydrogen (H2, D2) and impurity gasses (He, N2, Ne, Ar, Kr, Xe, etc.) into the LHD vacuum vessel for the plasma experiment and discharge cleaning, and at an emergency to stop or prevent the plasma disc…
