Generation and Application of Energetic Heavy Ion and X-ray via 12tw50fs Laser-solid Interaction
نویسندگان
چکیده
Energetic ions and ultrashort X-rays were generated by an intense ultrashort laser interacting with a copper target. Fast ions up to 3 MeV were observed with CR-39 nuclear track detector sheets when 7 TW laser was used. Cu ∼ Cu ions with the energy from 50 keV to 220 keV were detected with a Thomson parabola detector in the case of the laser power of 2.5 TW. Time-resolved X-ray diffraction was carried out using ultrashort X-rays generated from the copper target irradiated by the intense laser pulses. A change of diffraction patterns was observed in the X-ray diffraction from a GaAs(111) crystal irradiated by the ultrashort laser pulses.

Induction of cancer stem-like cells in A549 cells after exposure to carbon ions and X-rays
Background: Cancer stem-like cells (CSCs) play a crucial role in the initiation, progression, and recurrence of cancer. Evidence indicates that the high linear energy transfer (LET) carbon ion beam is more effective against CSCs than the conventional X-ray beam. Carbon ion radiotherapy is considered as a promising cancer strategy, however, information about whether, or not, new CSCs are induced...
متن کاملSynthesis of Three-Layered Magnetic Based Nanostructure for Clinical Application
The main objective of this research was to synthesize and characterize gold-coated Fe3O4 /SiO2 nanoshells for clinical applications. Magnetite nanoparticles (NPs) were prepared via co-precipitation. The results showed that smaller particles can be synthesized by decreasing the NaOH concentration, which in our case this corresponded to 35 nm by using 0.9 M of NaOH at 750 rpm. The NPs were then m...
متن کاملMicro-channels over the glass surface made by interaction of Ar+ laser beam and Ag+/Na+ ion-exchanged glasses
Micro-channels are made over the Ag+/Na+ ion-exchanged soda-lime glass surface by interaction of an intense Ar+ laser beam and the silver ions inside the glass matrix. The Ar+ laser beam reduces the Ag+ ions inside the matrix. The Ag+ atoms aggregate into silver nano-clusters around the interaction area, inside the glass matrix. Aggregation of the silver atoms and the thermal effects of the int...

متن کاملLaser based synchrotron radiation
Beams of x rays in the kiloelectronvolt energy range have been produced from laser-matter interaction. Here, energetic electrons are accelerated by a laser wakefield, and experience betatron oscillations in an ion channel formed in the wake of the intense femtosecond laser pulse. Experiments using a 50 TW laser (30 fs duration) are described, as well as comparisons with numerical simulations. T...
