摘要

中红外自由电子激光器(MIR-FEL)是实现基于高谐波产生(HHG)的高重复率阿秒硬x射线源的候选器件。自2018年以来，启动了一个新的项目，进行MIR-FEL驱动的HHG原理验证实验。为此，京都大学的MIR-FEL升级项目(KU-FEL)已经启动，以实现高峰值功率和超短脉冲操作。作为升级的第一步，改进了光电阴极驱动激光器，使其能够长宏脉冲光电阴极工作。本文将介绍KU-FEL长大脉冲光电阴极工作的结果。

Upgrade of Mid-Infrared Free Electron Laser at Kyoto University by Long Macro-pulse Photocathode Operation of the Existing RF Gun

A mid-infrared Free Electron Laser (MIR-FEL) is a candidate to realize a high-repetition-rate atto-second hard X-ray source based on the high harmonic generation (HHG). A new project to conduct a proof of principle experiment of HHG driven by a MIR-FEL has been started since 2018. For this purpose, upgrade project of MIR-FEL at Kyoto University (KU-FEL) has been started to achieve high peak power and ultrashort pulse operation. As the first step of the upgrade, a photocathode drive laser was improved to enable long macro-pulse photocathode operation. The results of the long macro-pulse photocathode operation of KU-FEL will be presented.
