| Abstract |
Betatron X-ray created by laser wakefield acceleration (LWFA) are of fundamental interest in plasma physics due to their broadband X-ray spectra, compact source size and ultra short duration. In particular, the femtosecond duration of electron bunches produced during LWFA offers the opportunity to study warm dense matter (WDM) in detail via pump/probe experiments. In this study, we used the SLAC MEC optical laser (Ti:S 800nm, 1J in 40 fs) focused in a gas cell to generate betatron X-ray. A spectroscopy technique called “single-hit spectroscopy” or “single photon counting” (SPC) can be used to characterize the betatron X-ray spectra. We will describe precisely this technique within the context of this experiment. First results of spectra characterization will be presented. |
