TL;DR: In this paper, a femtosecond Ti:sapphire laser pulse was used to enhance the radiation of soft x-rays from the CO2 clusters, and nanostructure images of 100-nm-thick Mo foils in a wide field of view (mm2 scale) with high spatial resolution (800nm) were obtained with high dynamic range LiF crystal detectors.

TL;DR: In this paper, the authors used a cluster jet containing Ar clusters to generate relativistic electrons up to 58 MeV with an electron charge of 2.1 nC, which is well described by a two-temperature Maxwellian.

TL;DR: In this article, a quasimonochromatic x-ray source with a source size of only 12μm has been applied to X-ray radiographic imaging of a biological specimen, resulting in high-resolution, high quality phase contrast images.

Laser pulse guiding and electron acceleration in the ablative capillary discharge plasma
Takashi Kameshima,Hideyuki Kotaki,Masaki Kando,Izuru Daito,Keigo Kawase,Yuji Fukuda,Liming Chen,T. Homma,S. Kondo,T. Zh. Esirkepov,N. A. Bobrova,Pavel V. Sasorov,Sergei V. Bulanov +12 more
TL;DR: In this paper, the results of experiments for the laser electron acceleration in the ablative capillary discharge plasma were presented, and the inner walls of the capillaries that underwent several tens of shots showed that the wall deformation and blistering resulted from the discharge and laser pulse effects.
