The generation of collimated, high brilliance $\gamma$-ray beams from astructured plasma channel target is studied by means of 2D PIC simulations.Simulation results reveal an optimum laser pulse pulse duration of$20\,\text{fs}$, for generating $\gamma$-photon beams of brilliances up to$10^{20}\,\text{s}^{-1}\text{mm}^{-1}\text{mrad}^{-2}\,(0.1\,\%\text{BW})^{-1}$and photon energies well above $200$ MeV in the interaction of an ultra-intenselaser (incident laser power $ P_L \geq 5$ PW) with a high-Z carbon structuredplasma target. These results are aimed at employing the upcoming laserfacilities with multi-petawatt (PW) laser powers to study the laser-drivennonlinear quantum electrodynamics processes in an all-optical laboratory setup.
