Caption

Experimental measurements demonstrate the relationship between electron charge, temperature, and EMP intensity as nitrogen gas jet pressure varies, which identifies that the variation in accelerated electron dynamics induced by laser energy and gas pressure constitutes a critical factor governing the intensity and distribution of electromagnetic pulses (EMPs).
