In the present study, we have been carrying out the development of overall experimental and simulation studies by using our own Laser photo-cathode RF gun which is one of the best accelerators for achieving the purpose. One of the developments, we have studied the RF deflector cavity as the candidate for the converter of electron beam structure from thin beam in space to time domain. We have succeeded the development of micro-slit by applying the FIB technology to obtain the high aspect ratio structures. Finally, we have obtained micro-slit devices with the aspect ratio of 15 with the slit size is around 100 nm.We have demonstrated the micro-spacing electron beam by using micro-slits. Further, we have operated the RF deflector cavity for the space to time conversion of electron beam, and we have succeeded the establishment of the basic technology by controlling the micro-bunched electron beam using the developed technology for the realization of coherent Compton scattering.

在本研究中，我们一直在使用我们自己的激光光电阴极射频枪进行整体实验和模拟研究的开发，这是实现这一目的的最佳加速器之一。其中一项进展是，我们研究了射频偏转腔作为电子束结构从空域到时域的细束转换器的候选者。我们通过应用FIB技术成功开发了微缝以获得高深宽比结构。最终，我们获得了深宽比为15、狭缝尺寸在100 nm左右的微狭缝器件。我们利用微狭缝演示了微间距电子束。此外，我们还操作了射频偏转腔来进行电子束的时空转换，并成功建立了利用所开发的技术控制微束电子束来实现相干康普顿散射的基础技术。
