Coherent Free Electron Radiation Sources

本研究项目是对以电子束为激光介质的电磁辐射相干产生的实验和理论研究。拟议的主要活动领域是：(A)短周期摇摆器(微摇摆器)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。在(A)项下进行研究的目的，是希望发展以较低电压运作的台式设备。(B)和(C)项下的研究部分是出于对用于下一代射频直线加速器的新型更高频率、高功率驱动器的渴望，以期在目前可用的基础上增加加速度梯度。(D)项下的理论研究将与实验项目紧密相连。

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.
