The dark matter puzzle is one of the most important fundamental physics questions in the 21 st century.There is no doubt that solving the puzzle will be a new milestone for human beings in achieving a deeper under-standing of nature.Herein,we propose the use of the Shanghai laser electron gamma source (SLEGS) to search for dark matter candidate particles,including dark pseudoscalar particles,dark scalar particles,and dark photons.Our simulations indicate that,with some upgrading,electron facilities such as SLEGS could be competitive platforms in the search for light dark matter particles with a mass below tens of keV.
