ULTRA-SHORT-PULSE ELECTRON DIFFRACTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an ultra-short-pulse electron diffraction device for tracking the change in the molecular structure of a sample in a femtosecond region in real time. SOLUTION: The ultra-short-pulse electron diffraction device comprises an ultra-short-pulse laser beam generation device 1, a cathode 3 where the ultra- short-pulse laser beam is applied from the ultra-short-pulse laser beam generation device 1, an acceleration device 4 for accelerating an electron pulse (e) that is generated from the cathode 3 and obtaining the short electron pulse (e), an interaction region (interaction section) 5 where the short electron pulse (e) is operated on a sample gas 6, and a means for observing an electron diffraction image at the interaction region 5.
