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. (C) 1997 E
