GeV ($\gamma_e$ > 2000) electron bunches from petawatt-laser-driven plasma accelerators can be converted to tunable, narrowband or to broadband continuum $\gamma$-ray ($h\nu$ > 10 MeV) pulses by Thomson backscattering (TBS) or bremsstrahlung, respectively. Inserting a plasma mirror (PM) near the accelerator exit converts electrons to $\gamma$-rays compactly and inexpensively [1], in a...
X-Ray fluorescence imaging (XFI) is a promising, new imaging method for in vivo localisation of low amounts of functionalised gold- nanoparticles (GNPs), enabling early cancer diagnostics and pharma- cokinetic tracking studies. At the moment, XFI is not applicable for human-scales, since the modality suffers from an intrinsic background, mainly caused by multiple Compton scattering processes....
Inverse Compton Scattering is one of the best ways to generate mono-energetic gamma rays. After Tsinghu Thomson Scattering X-ray source – TTX has been developed and used as an experiment tool for advanced x-ray imaging and other applications, XGLS with the gamma ray energy of 3MeV is now under commissioning. In this paper, we will mainly descript the very compact gamma ray source with photon...
A broadband (keV to MeV), high flux (1e12 photons/keV/sr) x-ray source from a hybrid laser plasma accelerator driven by picosecond lasers is characterized. The hybrid laser plasma accelerator uses self-modulated laser wakefield acceleration combined with direct laser acceleration to generate low divergence (<100 mrad), relativistic electron beams. These electrons are then used to produce...
