Abstract :
Summary form only given, as follows. The transient internal probe (TIP) diagnostic is designed to measure the magnetic field profile internal to hot, high density plasmas. A small magneto-optic probe is fired through the plasma at velocities in excess of 2 km/s. Magnetic fields are obtained by illuminating the probe from the front with an argon ion laser and measuring the amount of Faraday rotation in the reflected beam. First generation TIP probes are limited in that only one component of the magnetic field can be measured. The orthogonal TIP probe, however, has the capability of measuring magnetic fields which are perpendicular to the direction of probe travel. Orthogonal measurement capability can provide a full radial scan of the poloidal field profile and serves as a technology base for future multi-dimensional TIP probes. Magnetic field resolution of /spl plusmn/20 gauss and spatial resolution of 5 mm is expected with a system frequency response of 10 MHz. Progress in the development of the orthogonal TIP probe is presented.
