|Langmuir probes:||Two double probes for Te, Is measurement at up-stream and down-stream sides of the field lines (i.e. Mach probe), and a floating probe for potential measurement. Head and 5 electrodes are made of carbon fiber composite (CFC).|
|Spatial resolution:||1-2 mm in radial direction.|
It has provided high spatially resolved profiles of the local electron temperature (Te), ion saturation current (Is) for ion- and electron-side of the probe head.
|Scanning speed:||25cm for ~0.5s (~50 cm/s)|
|Driving component:||a compact pneumatic cylinder and steel springs.|
Total mass of the moving components is about 25kg.
|Position: P-9 section, divertor port|
|(2005) Probe head and electrodes were replaced.|
Position: P-9 section: X-point Reciprocating probe system and W-shaped divertor
