理查德·迈尔斯ECS-0079344这项提议是为了开发一种100元电子束阵列源，用于产生和控制体积空气等离子体。该开发项目将与新墨西哥州阿尔伯克基的桑迪亚实验室合作进行。电子束阵列源将允许研究体积填充空气等离子体和MHD过程，其温度远远低于热维持等离子体所需的温度，并且在其他条件下会导致电场驱动的等离子体中的电弧不稳定性。该磁共振成像设备将支持的研究领域包括：1)探索在低于2000K的温度下修改附着和复合机制的方法，以便将维持体积空气等离子体所需的功率降至最低。2)从高速中提取功率的研究，通过使用电子束的持续导电性，MHD处理低温(3000K)空气。3)开发MHD过程的新控制策略，使用100个电子束元件的电流来空间分布和时间调制导电性。4)研究用于反射电磁辐射的快速可重构等离子体阵列。该装置将由100个单独可控的电子束组成，排列成7厘米×7厘米，10×10阵列。阵列的大小已被选择为适合7特斯拉磁体，该磁体将用于引导电子，并将在增加电极的情况下，成为研究MHD过程的能量提取通道。

Richard MilesECS-0079344 This proposal is for development of a 100 element electron beam array source for the production and control of volumetric air plasmas. The development project will be undertaken in partnership with Sandia Laboratories in Albuquerque, NM. The electron beam array source will permit the study of volume filling air plasmas and MHD processes at temperatures far below those required for thermally sustained plasmas and under conditions which otherwise lead to arcing instabilities in electric field driven plasmas. The research areas that will be supported by this MRI equipment include following: 1) The exploration of approaches to the modification of attachment and recombination mechanisms at temperatures below 2000K in order to minimize the power requirements for sustaining volume air plasmas.2) The study of the extraction of power from high speed, low temperature (3000K) air by MHD processes through the use of electron beam sustained conductivity.3) The development of new control strategies for MHD processes using the currents of the 100 electron beam elements to spatially distribute and temporally modulate the conductivity.4) The study of rapidly reconfigurable plasma arrays for the reflection of electromagnetic radiation.The device will consist of 100 separately controllable electron beams arranged in a 7 cm by 7 cm, 10 x 10 array. The size of the array has been chosen to fit into a 7 Tesla magnet which will be use to guide the electrons and, with the addition of electrodes, will become the power extraction channel for the study of MHD processes.
