Basic Research on Coherent Inverse Compton Scattering for High Power Soft X-ray Genetation

在本研究中，我们一直在使用我们自己的激光光阴极射频枪，这是实现这一目的的最好的加速器之一，进行全面的实验和模拟研究的发展。其中，我们研究了射频偏转腔作为电子束结构从空间到时间域的转换器的候选者。我们成功地发展了微缝，应用FIB技术获得了高深宽比的结构。最后，我们得到了宽高比为15，狭缝尺寸约为100 nm的微狭缝器件，并利用微狭缝实现了微间距电子束。此外，我们已经操作的RF偏转腔的电子束的空间到时间的转换，我们已经成功地建立的基本技术，通过控制微聚束电子束使用开发的技术实现相干康普顿散射。

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.
