摘要:
Small‐angle neutral beam scattering is a promising technique to measure the local ion temperature in a hot plasma. We will show that in general a 10% accuracy in the temperature measurement can be obtained with a temporal resolution in the order of 1 ms and a spatial resolution of 10 cm. These values are less favorable than previous claims by Van Heeschetal.
