Abstract
A TV Thomson scattering system, which consists of three framing camera s with image intensifiers and cooled charge coupled device cameras, ha s been developed on Heliotron E with a minimum spatial resolution of 1 cm. The quantum efficiency of the framing camera is 6.5% at 700 nm. T he scattered light is detected as an image of 1000 x 1000 pixels. The number of spatial channels is equal to the number of divided regions o f this image. The calibration methods such as the spectral sensitivity , plasma light, stray light and so on are established. The examples of the detected data and the measured T-e profiles are shown.
