We investigated the interaction of a laser ablation plasma with a longitudinal magnetic field aiming to create a directionally moving plasma for high-flux and low-emittance ion injectors. To study the plasma dynamics, time-of-flight measurements and

Disseminated cryptococcosis is rare but can often become severe with a poor outcome. Given recent reports that matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analyser is useful for Cryptococcus species ide

Kα radiation from low charge chlorine is examined for cold dense plasma diagnostics. A relativistic atomic structure calculation shows that the transition energies of Kα lines are slightly shifted to a higher-energy side according to the degree of

A quasi-statically tamped target for warm dense matter (WDM) experiments using all-ion accelerator (AIA) is presented. We compare the target state and homogeneity based on the KEK AIA with and without injector. For making WDM based on KEK AIA (withou

Theoretical study of energy transfer in ultrahigh intensity laser plasma was performed using a computer code to analyze the polarization of the Cl–He α line. The Breit–Pauli R -matrix method was used to calculate elastic- and inelastic-scatterin
