Abstract

The invention provides a radiation source generation system based on a stacked chirp pulse sequence. The system can be applied to research about a transient dynamic mechanism. The radiation source generation system based on the stacked chirp pulse sequence comprises a mode-locked laser, a pulse frequency demultiplier, a pulse stacker, a pulse stretcher, a preamplifier, a main amplifier, a pulse compressor, an ultra-short laser pulse sequence, a pulse electron beam and an X-ray source pulse sequence. A high-repetition-frequency broadband chirp pulse source generated by the mode-locked laser is subjected to frequency demultiplication through the pulse frequency demultiplier, passes through the pulse stacker to obtain the stacked chirp pulse sequence, passes through the preamplifier and the main amplifier and then enters the pulse compressor, and the compressed ultra-short laser pulse sequence interacts with the pulse electron beam to generate the X-ray source pulse sequence.

Description

technical field [0001] The invention belongs to the field of generating a high-flux radiation source through the interaction of stacked chirped pulse sequences and pulsed electron beams or target materials, and specifically relates to a radiation source generation system based on stacked chirped pulse sequences. Background technique [0002] In high energy density physical diagnosis, material science research and biological science research, it is necessary to use short-pulse high-intensity radiation sources as diagnostic sources, including X-ray sources and particle radiation sources. In the study of some transient dynamic mechanisms, it is necessary to study the high time-resolution dynamic evolution characteristics of physical, chemical or biological processes in a short period of time. At present, methods based on high-intensity short-pulse radiation sources generated by the interaction of high peak power laser pulses with pulsed electron beams or target materials have ...
