Experimental Study and Theoretical Verification of Explosion-Proof Performance of Insulated Glass by Jinju Zhang, Xinjian Wang, Liqiong Wang, Pengchong Su

“…The research showed that the fragments scattered toward the center of the explosion source when the layer of the insulated glass face to the explosion wave front was broken, and the fragments mainly scattered in the direction of the shock wave propagation when it was completely broken. The theoretical calculation method based on the equivalent static load could be used to evaluate the explosion-proof performance of the insulated glass.…”

Fast plasma production by intense femtosecond extreme ultraviolet and x-ray pulses by C. Fasolato, E. Stellino, F. Sacchetti, C. Petrillo

“…The pump pulses, promoting electrons from delocalized valence band states, excite the system often through multiphoton absorption processes and/or shock wave propagation. Instead, the use of FEL radiation as a pump allows triggering electron transitions from bound, core states to nearly free levels above the Fermi energy, promptly generating a highly excited state, toward the warm dense matter regime. …”
