Abstract :
Summary form only given, as follows. The Large Helical Device (LHD) experiments has successfully started after the eight-years of construction period. The plasma is generated by ECRH of 84 and 82.6 GHz, and heated up by NBI and ICRF. For the electron density measurements of the LHD plasma, four kinds of diagnostics have been used a multi-channel FIR laser interferometer, a two color mm wave interferometer, a CO/sub 2/ laser imaging interferometer and a 3-channel tangential CO/sub 2/ laser polarimeter.
