(Sub-)picosecond surface correlations of femtosecond laser excited Al-coated multilayers observed by grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Toshinori Yabuuchi +22
Femtosecond high-intensity laser pulses at intensities surpassing can generate a diverse range of functional surface nanostructures. Achieving prec…
The importance of temperature-dependent collision frequency in PIC simulation on nanometric density evolution of highly-collisional strongly-coupled dense plasmas
Mohammadreza Banjafar, Lisa Randolph, Lingen Huang +17
Particle-in-Cell (PIC) method is a powerful plasma simulation tool for investigating high-intensity femtosecond laser-matter interaction. However, its simulation capability at high…
Nanoscale subsurface dynamics of solids upon high-intensity laser irradiation observed by femtosecond grazing-incidence x-ray scattering
Lisa Randolph, Mohammadreza Banjafar, Thomas R. Preston +28
Observing ultrafast laser-induced structural changes in nanoscale systems is essential for understanding the dynamics of intense light-matter interactions. For laser intensities on…
Proton beam quality enhancement by spectral phase control of a PW-class laser system
T. Ziegler, D. Albach, C. Bernert +24
We report on experimental investigations of proton acceleration from solid foils irradiated with PW-class laser-pulses, where highest proton cut-off energies were achieved for temp…
Towards a novel laser-driven method of exotic nuclei extraction-acceleration for fundamental physics and technology
Mamiko Nishiuchi, Hironao Sakaki, Katsuhisa Nishio +20
The measurement of properties of exotic nuclei, essential for fundamental nuclear physics, now confronts a formidable challenge for contemporary radiofrequency accelerator technolo…
Prepulse and amplified spontaneous emission effects on the interaction of a petawatt class laser with thin solid targets
Timur Zh. Esirkepov, James K. Koga, Atsushi Sunahara +17
When a finite contrast petawatt laser pulse irradiates a micron-thick foil, a prepulse (including amplified spontaneous emission) creates a preplasma, where an ultrashort relativis…
Review of Discrete X-Ray Sources in the Small Magellanic Cloud: Summary of the ASCA Results and Implication on the Recent Star Forming Activity
Jun Yokogawa, Kensuke Imanishi, Masahiro Tsujimoto +2
We made 22 observations on the Small Magellanic Cloud (SMC) and covered full regions by the end of the ASCA mission. We detected 106 discrete sources with a criterion of S/N > 5 an…
Nature of the Soft Spectral Component in the X-ray Pulsars SMC X-1 and LMC X-4
B. Paul, F. Nagase, T. Endo +3
We present here the results of an investigation of the pulse averaged and pulse phase resolved energy spectra of two high luminosity accretion powered X-ray pulsars SMC X-1 and LMC…
Centrally Peaked X-Ray Supernova Remnants in the Small Magellanic Cloud Studied with ASCA and ROSAT
Jun Yokogawa, Kensuke Imanishi, Katsuji Koyama +2
This paper presents ASCA/SIS and ROSAT/HRI results of three supernova remnants (SNRs) in the Small Magellanic Cloud: 0103-726, 0045-734, and 0057-7226. The ROSAT/HRI images of thes…
ASCA Observations of the Twin Supernova Remnants in the Large Magellanic Cloud, DEM L316
Mamiko Nishiuchi, Jun Yokogawa, Katsuji Koyama +1
We report results from an ASCA X-ray study of DEM L316, an emission nebula in the Large Magellanic Cloud (LMC) consisting of two closely-spaced supernova remnants (SNRs). The SIS i…
A Study of the Populations of X-ray Sources in the Small Magellanic Cloud with ASCA
Jun Yokogawa, Kensuke Imanishi, Masahiro Tsujimoto +4
The Advanced Satellite for Cosmology and Astrophysics (ASCA) has made multiple observations of the Small Magellanic Cloud (SMC). X-ray mosaic images in the soft (0.7--2.0 keV) and…
ASCA Observations of GRO J1744-28
M. Nishiuchi, K. Koyama, Y. Maeda +7
We report the ASCA results of the bursting X-ray pulsar \gro, which was observed in February 1996 and March 1997. The source flux in the 2--10 keV band was erg/s…
