Study of fast electron propagation in ultraintense laser pulse interaction with solid targets from Optical Transition Radiation diagnostics
Abstract
In the context of the fast electron transport in solid matter and the fast ignitor scheme, we report on time-integrated and -resolved measurements of the target back-side visible irradiance performed at LULI with the 100TW laser. From Optical Transition Radiation, we estimate the geometry of the high energy electron flux through the target, which also gives evidence of the material heating by the electron energy deposition. The temperature is determined either by absolute measurement of the back-side emission or by the determination of the color temperature.
