摘要：

An ASDEX-type Thomson scattering system (YAG Thomson) with an improved performance (100 Hz repetition rate and 1.5 cm spatial resolution) was designed and constructed for the JIPPT-IIU tokamak. Efforts were concentrated on realizing a large solid angle of collection optics (0.08 sr), high throughput of polychromators (>64%) and high quantum efficiency of detectors (80% at 900 nm), which, together, yield high-quality data even with a small laser energy (0.4 J) delivered by a 100-Hz-repetition-rate Nd:YAG laser and with a short scattering length (1.0 cm). The compactness of the polychromators also contributes to achieving a high spatial resolution.
