 note = {Poloidail and radial magnetic field fluctuations less than 100 kHz are measured with a newly developed movable magnetic probe array in the JIPP T-IIU tokamak. The probe array protected by a carbon/carbon - composite with 20% boron is inserted beyond the last closed flux surface (LCFS) up to r/a simeq 0.77 without deleterious effect on ohmically and neutral beam heated plasmas. From the radial variation of the fluctuation amplitude just outside LCFS the poloidal mode number is estimated to be m leq 4 for low frequency coherent part (f < 30kHz) and m~10 for relatively high frequency incoherent one (f > 50kHz)},
