Abstract

X-ray Free Electron Laser (XFEL) has been known to be a dream X-ray source opening an epoch in X-ray science with the characteristics of femtosecond pulse, perfect transverse coherence, and ultra-high brightness. Here we introduce the XFEL source shortly and report the status of the worldwide XFEL facilities, and then the experimental instrumentations for XFEL are reviewed in their conceptual classification scheme. Scientific examples and applications proposed in the research area of magnetism for XFEL are briefly mentioned. Finally are summarized the facility overview and the scientific proposals for PAL-XFEL project.

X-선 자유전자레이저(XFEL)는 펨토초의 펄스형태, 완벽한 결맞음 및 고휘도 특성으로 X-선 실험과학분야의 새로운 시대를 예고하는 꿈의 X-선 광원장치로 언급되고있다. XFEL에 관한 간략한 소개와 현재 세계적으로 진행되고 있는 XFEL 시설현황을 살펴보고, 대표적인 실험장치를 개념적으로 분류해서 정리해 보고자 한다. 특히 자성연구분야와 관련된 제안 및 연구사례를 간략하게 언급하고, 지금 현재 진행 중인 포항가속기연구소의 XFEL 프로젝트의 개요와 XFEL 활용을 위해서 제안된 대표적인 과학프로그램을 살펴보고자 한다.
