Experimental files for Dynamics of plasmas produced by a laser pulse, inside a dense gaseous target, formed in an ambient gas

<p>Time development of plasmas produced by interaction of laser pulses, with a nitrogen gas, was investigated. The interaction&nbsp;took place inside a small portion of dense nitrogen gas injected temporarily into a chamber filled with the gas under low pressure.&nbsp;High-temperature plasmas produced directly by the laser pulse were a source of soft x rays and charged particles, ionizing and exciting the&nbsp;surrounding gas. In this way, low-temperature plasmas were produced. The formation of high-temperature plasmas was studied using soft&nbsp;x-ray spectroscopy and x-ray streak imaging. Low-temperature plasmas formed at various distances from the laser focus were investigated&nbsp;using an optical streak camera. The experimental data.zip file contains the experimental data from an X-ray spectrograph, X-ray streak&nbsp;camera and optical streak camera.</p> <p>Work supported by the National Science Centre, Poland,&nbsp;Grant Agreement No. UMO-2020/39/B/ST2/00509</p>
