摘要：

Electrostatic fluctuations have been measured in a large reversed-field pinch, and are large (approximately n(e)/n approximately 20%-40%, approximately T(e)/T approximately 10%-25%). Frequency and wave-number spectra are broad (DELTA-n approximately 70-150, DELTA-m approximately 3-6), and differ from measured magnetic fluctuation spectra. The transport inferred from correlation measurements indicates that electrostatic fluctuations can account for significant particle losses, but contribute < 15% to energy loss.
