X-ray absorption tomography employing a conical shell beam.
We demonstrate depth-resolved absorption imaging by scanning an object through a conical shell of X-rays. We measure ring shaped projections and apply tomosynthesis to extract optical sections at different axial focal plane positions. Three-dimensional objects have been imaged to validate our theoretical treatment. The novel principle of our method is scalable with respect to both scan size and...
متن کاملInvestigation of laser-irradiated Ar cluster dynamics from K-shell x-ray emission measurements.
Intense (up to a few 10(17) W/ cm2) femtosecond (down to 40 fs) laser pulses are focused onto a partially clusterized argon gas jet. The target was previously characterized and optimized in order to get a homogeneous and dense jet of clusters with a well controlled size. The interaction leads to x-ray emission that is absolutely calibrated and spectrally resolved using a high resolution time-in...
متن کاملIntense high-contrast femtosecond K-shell x-ray source from laser-driven Ar clusters.
Bright Ar quasimonochromatic K-shell x ray with very little background has been generated using an Ar clustering gas jet target irradiated with a 30 fs ultrahigh-contrast laser, with a measured flux of 2.2×10(11) photons/J into 4π. This intense x-ray source critically depends on the laser contrast and intensity. The optimization of source output with interaction length is addressed. Simulatio...
متن کاملGeneration of 25-TW Femtosecond Laser Pulses at 515 nm with Extremely High Temporal Contrast
We report on the frequency doubling of femtosecond laser pulses at 1030 nm center wavelength generated from the fully diode-pumped laser system POLARIS. The newly generated pulses at a center wavelength of 515 nm have a pulse energy of 3 J with a pulse duration of 120 fs. On the basis of initially ultra-high contrast seed pulses we expect a temporal intensity contrast better 10 200 ps before th...
متن کاملSimulation of monoenergetic electron generation via laser wakefield accelerators for 5–25 TW lasers
In 2004, using a 3D particle-in-cell PIC model F. S. Tsung et al., Phys. Rev. Lett. 93, 185004 2004 , it was predicted that a 16.5 TW, 50 fs laser propagating through nearly 0.5 cm of 3 1018 cm−3 preformed plasma channel would generate a monoenergetic bunch of electrons with a central energy of 240 MeV after 0.5 cm of propagation. In addition, electrons out to 840 MeV were seen if the laser pro...
