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.

Richard MilesECS-0079344 该提案旨在开发 100 元件电子束阵列源，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在远低于热持续等离子体所需温度的温度下以及在否则导致电场驱动等离子体中电弧不稳定的条件下研究体积填充空气等离子体和MHD过程。该 MRI 设备支持的研究领域包括： 1) 探索在 2000K 以下的温度下修改附着和重组机制的方法，以尽量减少维持体积空气等离子体的功率需求。 2) 研究通过使用电子束持续电导率，通过 MHD 过程从高速、低温 (3000K) 空气中提取能量。3) 使用 100 个电子束元件的电流开发 MHD 过程的新控制策略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 个独立可控的电子束组成，排列成 7 厘米 x 7 厘米、10 x 10 阵列。 该阵列的尺寸已选择适合 7 特斯拉磁体，该磁体将用于引导电子，并且通过添加电极，将成为 MHD 过程研究的功率提取通道。
