This research program is for study experimentally and theoretically of the coherent generation of electromagnetic radiation using electron beams as the lasing medium. The proposed major areas of activity are: (a) Research on short period wigglers (microwigglers); (b) Electron cyclotron maser (CARM) amplifier; (c) High efficiency, 35 GHz UBITRON; (d) Theoretical studies of free-electron laser mechanisms and novel accelerators. Studies under (a) are motivated by a desire to develop table-top size facilities operating at lower voltages. Studies under (b) and (c) are in part motivated by a desire for novel higher frequency, high power drivers for use in the next generation of RF LINAC's, with the view of increasing the acceleration gradients above those available at present. The theoretical studies under (d) will be tied closely to the experimental projects.

该研究项目旨在从实验和理论上研究使用电子束作为激光介质相干产生电磁辐射。 拟议的主要活动领域是： (a) 对短周期摆动器（微摆动器）的研究； (b) 电子回旋脉泽（CARM）放大器； (c) 高效率，35 GHz UBITRON； (d) 自由电子激光机制和新型加速器的理论研究。 (a)项下的研究是出于开发在较低电压下运行的桌面尺寸设施的愿望。 (b) 和 (c) 项下的研究部分是出于对用于下一代 RF LINAC 的新型更高频率、高功率驱动器的渴望，以期将加速梯度增加到目前可用的加速梯度以上。 (d) 项下的理论研究将与实验项目密切相关。
