SGER: Measurement of the Horizontal Component of the Electric Field from Very Close Lightning

本研究的目的是测量和解释非常接近雷击的电场的水平分量。该实验将于1991年夏季在肯尼迪航天中心进行，并将涉及火箭触发的闪电。所提出的测量和分析对于闪电通道下部的建模非常重要，特别是闪电附着过程和来自非常近的闪电与架空电线的电磁能量耦合。来自瑞士洛桑联邦理工学院的电磁学研究小组提出与佛罗里达大学分享他们的电场测量设备：2个Thomson CSF电场传感器（宽带EMP传感器非常适合近距离闪电测量），一个LeCroy 4通道数字示波器和一台控制计算机。此外，该小组将提供一名有经验的博士生，可能还有一名研究生，他们将于1991年夏季前往肯尼迪航天中心，与我们的研究小组合作，进行拟议的电场测量，并将瑞士设备带到盖恩斯维尔，并在1991年春季帮助校准。

The objective of this research is the measurement and interpretation of the horizontal component of the electric field very close to the lightning stroke. The experiment will take place at the Kennedy Space Center during Summer 1991 and will involve rocket-triggered lightning. The proposed measurements and analysis are important for the modelling of the lower part of the lightning channel, in particular the lightning attachment process and the coupling of electromagnetic energy from very close lightning to overhead wires. The electromagnetics research group from the Ecole Polytechnique Federal de Lausanne in Switzerland has offered to share with the University of Florida their electric field measuring equipment: 2 Thomson CSF electric field sensors (wideband EMP sensors ideally suited for close lightning measurements), a LeCroy 4 channel digitalizing oscilloscope, and a controlling computer. Additionally the group will provide one experienced Ph.D. student and possibly one additional graduate student who will travel to the Kennedy Space Center for Summer 1991 to cooperate with our research group in making the proposed electric field measurements and who will bring the Swiss equipment to Gainesville and help in the calibration in Spring 1991.
