Broadband X-ray generation by large krypton clusters under the effect of relativistic femtosecond laser pulses

Abstract: This paper presents a phenomenological analysis of thermodynamic parameters of a pulsed supersonic gas jet in a conical nozzle. Conditions have been found out for the condensation and formation of large krypton clusters resulting from phase transitions during adiabatic expansion of gas through the nozzle into vacuum. We have identified the phase state of the large clusters (submicron droplets consisting of ∼107 monomers) forming in the jet and obtained a high yield of X-rays from a cluster nanoplasma produced … Show more

“…The scope of their applications is related to fundamental physical research [1], materials science [2], and thermonuclear energy [3]. Currently neutron beams are typically generated by nuclear reactors or influence of super-intense femtosecond laser pulses on clusters appearing as a result of supersonic gas expansion into vacuum, cluster nanoplasma can be a source not only of high-energy ions [7], broadband x-rays [8], but also neutron bursts (if deuterated substances are used to form the cluster jets) [9]. Thus, this can serve as the basis for the emergence of a new class of neutron source.…”
