Enhanced target normal sheath acceleration of protons from intense laser interaction with a cone-tube target

Laser driven proton acceleration is proposed to be greatly enhanced by using a cone-tube target, which can be easily manufactured by current 3D-print technology. It is observed that energetic electron bunches are generated along the tube and accelerated to a much higher temperature by the combinatio...
