Abstract:
A new Stark effect diagnostic was used to measure the E-field distribution of Langmuir waves in beam-plasma turbulence. Abrupt beam cut off causes the distributions amplitude to decay exponentially in a microsecond, in disagreement with recent power law scalings deduced from cascade theory. jhd
