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，我们一直通过使用自己的激光照相RF枪来开发整体实验和仿真研究，这是实现目的的最佳加速器之一。其中之一，我们研究了RF偏转器腔是电子束结构从薄束到时域到时域的转换器的候选者。我们通过应用FIB技术来获得高纵横比结构来成功开发微型扫描。最后，我们获得了15个纵横比的微型设备，其缝隙尺寸约为100 nm。我们已经使用微缝线证明了微间距电子束。此外，我们已经操作了电子梁的时间转换空间的RF偏转器腔，并通过使用开发的技术来实现相干的康普顿散射来控制基本技术的时间转换。
